💬 Sensebender Micro

fearoffish · 30 Oct 2016, 19:46

Anyone managed to get this working with PlatformIO (through Atom) yet? I'm struggling.

phildefer · 20 Nov 2016, 10:58

I upgrade my sensebender firmware with the new one (V1.4), and i have a question.

In the sketch (https://www.mysensors.org/hardware/micro) the line

//#include <avr/power.h>

is commented.

Is it "normal" or is it a mistake ?

tbowmo · 21 Nov 2016, 07:42

@phildefer

I think it's a leftover from a cleanup at some point in time. Not used anymore.. The MySensors core library is handling the sleep mechanism now.

denisvdb · 6 Jan 2017, 15:13

To reprogram the sketch in a sensbender micro, wich board must be selected in the arduino prg?
I have problem with inclusion in jeedom, the command are not loaded.
thx

marceltrapman · 17 Jan 2017, 00:01

@fearoffish did you manage to get this working?
And, if so, what was the issue?

I am looking into changing to PlatformIO on Atom or even CLion...

loic13 · 23 Jan 2017, 16:22

Hi, I'm getting this error message when compiling the sketch with the 2.1.1 MySensors library:
SensebenderMicro:168: error: 'getConfig' was not declared in this scope
isMetric = getConfig().isMetric;

I just commented out the line as workaround, but not sure that its correct.

hek · 23 Jan 2017, 18:12

Hmm.. The api was recently changed to getControllerConfig().isMetric;

I'll update the example.

loic13 · 23 Jan 2017, 18:14

Thank you.

Toyman · 8 Feb 2017, 13:53

How difficult is to replace 0402 components with 0603 or 0804 components in Eagle? I am too old for 0402 soldering :-)))

tbowmo · 8 Feb 2017, 14:56

@Toyman

Not that hard, but you'll probably need to redesign the board, to get room for the larger components.

Another option is to order the board pre-assembled from our partner, itead studio

martinhjelmare · 8 Feb 2017, 19:40

I've tested to upload a sketch to the Sensebender Micro using platformio.

Put the following JSON into a json file in a folder named boards either in the MySensors library folder (your project in platformio), or somewhere else on the search path. Use the name of the json file in platformio.ini in the board setting. See for more info:
http://docs.platformio.org/en/latest/platforms/creating_board.html

Create a folder named boards in MySensors project folder.
Create a file in boards named sensebendermicro8MHz.json.

{
  "build": {
    "core": "arduino",
    "extra_flags": "-DARDUINO_ARCH_AVR -DARDUINO_AVR_PRO",
    "f_cpu": "8000000L",
    "mcu": "atmega328p",
    "variant": "standard"
  },
  "frameworks": [
    "arduino"
  ],
  "fuses": {
    "efuse": "0x06",
    "hfuse": "0xD2",

    "require_upload_port": true,
    "speed": 57600
  },
  "url": "https://github.com/mysensors/SensebenderMicro",
  "vendor": "MySensors"
}

Add an env in platformio.ini.

[env:sensebendermicro8MHz]
platform = atmelavr
framework = arduino
board = sensebendermicro8MHz
lib_deps = MySensors

Compile sketch.
Upload sketch.

I think I've got the settings correct, but it was the first time I did this. But it's tested and works as far as I can see.

Should we add a JSON file to one of the mysensors repos on github?

marceltrapman · 10 Feb 2017, 22:24

I have a bunch of W25X40CLSNIG-ND lying around.
They have the same size and same layout as far as I can see.

Is my thinking correct that I should be able to simply replace the AT25DF512C-SSHN-B, change the sketch and use it?

tbowmo · 10 Feb 2017, 22:51

@marceltrapman

If it's a jedec compatible flash, then you should be able to swap.. But what is the usecase of a larger flash? You can't execute code in the external flash.. So for OTA you still only have a bit under 32Kbyte usefull space..

marceltrapman · 10 Feb 2017, 23:23

@tbowmo no case at all, just that I have them and otherwise probably won't use them..

Michiel van der Wulp · 26 Feb 2017, 16:20

To reprogram the sketch in a sensbender micro, wich processor frequency do I choose?

After choosing Board "Sensebender Micro", the menu in Arduino 1.6.12 has choice Processor "Atmega328 8MHz" and "Atmega328 1MHz".
My code seems to be executed equally fine with both settings.
But the Arduino Serial Monitor not:

If I choose the 1MHz version, the Serial monitor only produces garbage, whatever setting I choose for baud (in the sketch and in the serial monitor UI).

If I choose the 8MHz version, the serial monitor works fine.

I am confused. The Sensebender is a 1MHz device, isn't it? Is it able to run on 8MHz too?

tbowmo · 26 Feb 2017, 18:11

@Michiel-van-der-Wulp

No, it runs at 8Mhz. It is asleep most of the time, so running at 8Mhz is actually more battery conserving, than running at 1Mhz (in theory), as shown in calculations over in this post. This is due to the shorter time powered on, when running at 8Mhz, compared to running at 1Mhz.

Michiel van der Wulp · 26 Feb 2017, 21:36

OK, I understand.
My confusion was caused by the second sentence at https://www.mysensors.org/hardware/micro : "... it operates at 1Mhz ..."
That's a mistake then?

tbowmo · 26 Feb 2017, 21:42

@Michiel-van-der-Wulp

Yes, sorry that was a false statement. I have modified the description, so that it now states that the Micro is running at 8Mhz.

marceltrapman · 27 Feb 2017, 21:55

I am thinking of expanding the Sensebender Micro and learn Kicad in the process.

Unfortunately every attempt to convert from Eagle to Kicad failed.

Is there a Kicad version available or did any of you manage to convert the project?

tbowmo · 28 Feb 2017, 05:22

@marceltrapman

There is no kicad project available for the Sensebender Micro, I tried to convert it myself, but didn't succeed with it either.

blacey · 28 Feb 2017, 06:27

@tbowmo said in Sensebender Micro:

@marceltrapman

I haven't tried this Eagle->KiCAD convertor myself but it might do the trick or at least reduce a lot of the manual labor to convert...

There's even a tutorial video.

tbowmo · 28 Feb 2017, 08:27

@blacey

thanks for finding that tutorial.. Might give it a spin, and see if I can convert the sensebender micro to kicad

blacey · 28 Feb 2017, 15:46

@marceltrapman The author updated his repo within the past few days so you could open an issue on his GitHub repo to see if he can help...

tbowmo · 1 Mar 2017, 21:53

@marceltrapman

Just tried the scripts from the url that @blacey mentioned above on the sensebender micro eagle files.. And got a semi working thing in kicad..

And it seems that at least the forward annotation from schematics to pcb is working like it should..

marceltrapman · 1 Mar 2017, 21:53

@tbowmo Nice, I will try again (probably sunday or so)...

meddie · 6 Mar 2017, 21:39

Hey together,
i have a question, because i have some capacity troubles. I used the example sketch from sensebender micro that meassures the temperature and humidity but i have additional activated the signing and encryption and now i got over the availible space 109%.
use anybody from you all the features? what i have to do?
thank you

nldroid · 11 Mar 2017, 13:57

Re: Sensebender Micro
I'm trying to flash the sketch to the sensebender micro using the Arduio IDE.

I bought the sensebender micro with the suggested FTDI programmer.

I connected the programmer to the sensebender and plugged in the USB cable.

My windows 7 installation finds the device and installs the driver as USB Serial Port (COM3). The driver is from FTDI. The hardware device id is: FTDIBUS\COMPORT&VID_0403&PID_6001

In the Arduino IDE, i've selected Board: Sensebender Micro, Processor: Atmega 328 8Mhz, Port: COM3.

I tried using USBasp, made a clone with the right hardware id's and tried that. I tried AVRIsp Mk II.

Whatever i try, avrdude.exe tells me it can't find the device:

Anyone knows what's wrong?

meddie · 13 Mar 2017, 14:33

Hey together,

i have an problem, i had some troubles with the space on the sb micro, i have removed the #define my_debug that solved my space problem, but now i have observed that the node is starting and sends few times the temp and humidity but after the few times nothing happens anymore.
i observed, when i hold the sensor in the fingers so that it will be worm, and start the node then it sends all minute the temp, but when the temp goes down to the room temperature then the node should send only when the humidity or temp changes over the threshhold, so in the room i dont have much changes and i think that when the node does not send about a longer time, that the the problem comes up.
I tested it in some different distances, on another floor but in very short distance too. I dont think that is a radio problem.
What do you think about?
The Problem is, that i cant debug the node because i disabled it because of space problems.
Thank you

meddie · 13 Mar 2017, 22:06

ok one more thing i found, when i close the serial monitor and start it again, i get the correctly output again, and i see in fhem the new readings.

but i cant understand what happens why stop the node to transmit the correct readings

qqlapraline · 15 Mar 2017, 22:03

@meddie, do you use the default sketch for sensebender ?
If this is the case, please notice that after 5 measures, the clock speed is lowered to 1 Mhz. It means that the serial output won't work anymore using the default baud speed.
And, when you restart the serial monitor, it starts all over again from measure number 1.
Hope this helps.

QQ.

meddie · 15 Mar 2017, 22:31

@qqlapraline
oh yes it does! It explains why i get the € signs in the serial monitor. But why does the node not send to my FHEM Controller? Depends it also on it, that the node switch to 1 Mhz and cant send anymore?
Thank you very much for your answer, its very helpfull.
Greets Eddie

tbowmo · 16 Mar 2017, 05:36

Hmm I actually thought that this feature with switching to 1mhz was removed, as my calculations show that it (in theory) will use more current, than running at 8mhz (due to the fact that it sleeps most of the time)

Michiel van der Wulp · 16 Mar 2017, 18:40

@tbowmo : The code to switch the frequency back to 1MHz is still there at https://www.mysensors.org/view/1/Sensebender-Micro.
Should it be removed?

Wavemaker · 26 Mar 2017, 13:19

Is it possible to directly connect a RFM69* module to the Sensebender Micro? Or do I need the (rather costly) NRF2RFM69 to do that?

mfalkvidd · 26 Mar 2017, 16:15

@Wavemaker welcome to the community!
You can spend your time instead of your money to do exactly what the adapter does, no need to buy it.

tbowmo · 26 Mar 2017, 16:23

@Wavemaker

What is costly? If you grab the gerbers for the nrf2rfm69, send them to dirtypcbs (or use the link provided in the thread and order the pre uploaded gerbers at dirtypcbs) you'll get around 30 modules for 12$..

Wavemaker · 27 Mar 2017, 19:07

@tbowmo Aha, yes, well I was looking at the cost of just one adapter to test. But you're right, in larger quantities it's not costly.

meddie · 28 Mar 2017, 10:33

@Michiel-van-der-Wulp
Can you tell me where in the code is the switch to 1 MHz? I still have the problems that my node dosnt send anymore. It works for several hours but after then it dont send anything.

In programming i am not good, and so i cant find the switch.
Thank you very much.
Greets Eddie

Michiel van der Wulp · 28 Mar 2017, 11:13

@meddie : Sure, I can:

The following is an extract from the code shown at https://www.mysensors.org/view/1/Sensebender-Micro, from the "loop()" function:

#ifndef MY_OTA_FIRMWARE_FEATURE
  if ((measureCount == 5) && highfreq) 
  {
    clock_prescale_set(clock_div_8); // Switch to 1Mhz for the reminder of the sketch, save power.
    highfreq = false;
  } 
#endif

If you remove these lines, it will stay on 8MHz.
(I did not test this but I am quite sure)

meddie · 28 Mar 2017, 11:15

@Michiel-van-der-Wulp
thank you i will test it the next few days

Dominic Amann · 30 Oct 2017, 14:24

I assume there is no exposure to the SPI bus on this board?

sundberg84 · 30 Oct 2017, 14:37

@Dominic-Amann from the hardware site:

MYSx 2.6 with
Dedicated UART
Dedicated SPI
Dedicated Interrupts
I2C bus (shared with onboard eeprom)

Dominic Amann · 30 Oct 2017, 14:41

Ah - right, the radio connector uses SPI.

tbowmo · 30 Oct 2017, 19:14

@Dominic-Amann

There are multiple SPI ports in use, one of them is dedicated to the expansion header (which follows MYSx 2.6 standard)

RWoerz · 10 Nov 2017, 00:45

Can somebody please post what this boards current draw is at 8Mz w/wo a radio. Because it will live in a crawl space It's going to be plugged in. I've also added a very simple water detector.

tbowmo · 10 Nov 2017, 10:23

@RWoerz

normal operating frequency is 48Mhz (if I remember right).. If I remember right, then there is no options in arduino to switch the frequency to 8Mhz..

sburlot · 27 Dec 2017, 11:31

Beware that the Si7021 can return a RH value < 0 or > 100, and Domoticz will not store it. Clamp the humidity to a valid range to avoid losing values.

Lately, my Sensebender reported values of 101-104 during the night. Took me some time to understand why Domoticz complained it didnt receive any values.
It received these values, but didnt like them.

See section 5.1.1 of the Si7021 datasheet says:
Due to normal variations in RH accuracy of the device as described in Table 4, it is possible for the measured value of %RH to be slightly less than 0 when the actual RH level is close to or equal to 0. Similarly, the measured value of %RH may be slightly greater than 100 when the actual RH level is close to or equal to 100. This is expected behavior, and it is acceptable to limit the range of RH results to 0 to 100%RH in the host software by truncating values that are slightly outside of this range.

dklinkman · 31 Jan 2018, 00:48

So cool that the micro as a node reports its battery level to the UI (I'm still on the FTDI power, hence > 100%)

mvader · 16 Apr 2018, 00:36

Am I able to remote reboot the sensebender micro? I can send an OTA firmware if i manually press the reset button.
but can i use the reboot command in MYScontroller? it doesn't seem to do anything when issued.

tbowmo · 16 Apr 2018, 06:59

@mvader

Is it the default dualoptiboot bootloader? Then the bootloader itself does not support OTA FW. You need to put a sketch on it, that supports OTA. (Default sensebender micro sketches doesn't)

mvader · 17 Apr 2018, 02:06

@tbowmo said in Sensebender Micro:

@mvader

yes it's the default bootloader. yes i have OTA added to the sketch. it works if i reset the device via manual reset. but what i'd like to do is send the reboot command from myscontroller. but it seems to do nothing ever. does the bootloader support reboot? or is that something i also have to add to the sketch?

situation: i have about 15 sensors all over the house. if i update, i'd like to be able to assign the firmware, and then issue the reboot command. so upon reboot, they take the assigned firmware. what i don't want to do is have to go to each one and manually press the reset button to get it to take the firmware. i'm sure it's healthier to run up and down 3 flights of stairs. but i'm lazy

tbowmo · 17 Apr 2018, 06:08

@mvader

The sketch should support reboot, try sending I_REBOOT to one of your nodes (info can be found here, look under internal messages)

I haven't tried it myself yet, as I haven't touched my sensebender micros for ages..

joaoabs · 26 Apr 2018, 11:56

Hi,
Three questions regarding SenseBender Micro:

What board should I configure in Arduino IDE in order to upload sketches? Would it be equivalent to Arduino mini pro, or is there any "board library" to load ?(Didn't find it, Woudn't it make sense to be included in the examples/Libraries pack?)...
(Found it: https://github.com/mysensors/ArduinoBoards . If you look between the photos above there is a simple link lost in the between)
MySensors Admins: Just a small suggestion: As it is now, - a simple link between photos is easily overlooked. Can't you place it near the specs where it should be more visible?
It has an I2C bus for the SI7021, but it seems the ATSHA204A (which I believe its I2C also) is connected to another pin (a3). Does this mean it has two I2C buses?
Can anyone confirm that the port that measures the battery voltage is A0?

Thanks,
Joaoabs

Anticimex · 26 Apr 2018, 12:19

@joaoabs we do not support I2C variant of atsha204a. Only single wire variant.

tbowmo · 26 Apr 2018, 18:40

@joaoabs

It uses the internal vref to measure the battery voltage. Some of the theory is described here https://www.sciencetronics.com/greenphotons/?p=1521

joaoabs · 26 Apr 2018, 19:27

For the battery powering voltage measuring do you mean that this is not needed after all? (https://www.mysensors.org/build/battery#measuring-and-reporting-battery-level)
It would be just a matter of enabling the flag "#define BATT_SENSOR 199 " and no resistors needed?

tbowmo · 26 Apr 2018, 20:48

@joaoabs

Yes, when you power it directly of f.ex. two AA batteries, then you can use the secret trick mentioned in that article that I linked to, for measuring battery voltage without external resistors.

joaoabs · 2 May 2018, 15:10

Sorry for the dummy question, but my SenseBender Micros came with a small white sticker on top of the Si7021 sensor (like in the pictures above). Is it supposed to be removed or to stay like that?

Anticimex · 2 May 2018, 15:34

@joaoabs the datasheet for the device clarifies that I believe

NailMan · 11 May 2018, 22:16

Hello!

Help me understand why the sketches are not loaded in Sensebender Micro - there is a synchronization error:
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x82
....
avrdude: stk500_getsync() attempt 9 of 10: not in sync: resp=0x82
avrdude: stk500_recv(): programmer is not responding

FTDI connected via 3.3V jumper
Another device built on the SB Micro with SB bootloader is also not flashed with the same error, but on the PC of my friend, sketches successfully loaded into the device and on my PC are given the correct data when working sketch
device and serial port are selected correctly
mySensors Lib and device packs(AVR, SAMD) installed with standard lib and device managers(and also added path https://raw.githubusercontent.com/mysensors/ArduinoBoards/master/package_mysensors.org_index.json in the settings menu)
at the same time if I take a pure Pro Mini and load into it any sample sketch of mySensors package - it will successfully do it and will work.

What am I doing wrong and how do I get the Sensebender Micro to take sketches?

tbowmo · 12 May 2018, 05:31

@nailman

Did you select the sensebender micro as target in Arduino? Is it the same FTDI device that is used on both computers?

NailMan · 13 May 2018, 13:27

@tbowmo
Yes, of course, I chose the target device "Sensebender Micro -> "Atmega328p, 1mhz" and "Atmega328p, 8mhz"(for device (RGBW controller) based on SB Micro with 8Mhz quartz resonator).

I tried three different FTDIs.

With any other Arduino (with native loaders) there are no problems with these FTDI adapters.

alexsh1 · 13 May 2018, 14:02

@nailman At what Mhz does your RGBW Controller is running now?
It seems to be the problem is in identifying the correct board.

If I have a board running at 1Mhz and try to program it at 8Mhz, similar to your error would come up, i.e. not in sync

tbowmo · 9 Jul 2018, 21:38

Unless the bootloader is reprogrammed, then it defaults to 8mhz, and you have to actively set registers to run at 1mhz in your sketch.

Do you have a ISP programmer? If yes, could you make a memory dump, and send it to me?

joaoabs · 1 Jun 2018, 00:44

Hello,
Coming back to the battery powering topic: I was checking some SlimNode code and it uses #include <Vcc.h> library to report battery level. I can see in that the example code above doesn't use it. Does anyone know what is the difference? Which is better?
Thanks,

tbowmo · 1 Jun 2018, 08:41

@joaoabs

Could you post a link to the code from slimnode?

joaoabs · 1 Jun 2018, 10:21

Hi,

The slimnode original thread has a few (not sure anymore which example I'm using now because the thread is huge and I've lost track of it)
Here is one example:
https://forum.mysensors.org/topic/2067/my-slim-2aa-battery-node/306

and other:

tbowmo · 3 Jun 2018, 06:53

@joaoabs

The library use the exact same method to read VCC, as the Sensebender Micro example. It's just the functions that is extracted into a library (which I think have been done by @Yveaux )

NailMan · 9 Jul 2018, 21:38

@tbowmo
I apologize for the delay in replying, I was very busy with work.

It turned out to be some mystical incompatibility of the FTDI and Sensbender Micro or a device based on its loader. Three versions of my FTDI refused to work with Sensbender Micro, but they worked with regular Arduino, and the fourth one, bought on AliExpress, works perfectly normal. Externally, all the same, only those that do not work with Sensbender Micro, the labeling of the chip differs slightly in the quality of engraving on the plastic.

Maybe it's fake or some kind of non-standard chips.

alexsh1 · 10 Jul 2018, 12:07

@nailman There are a lot of fake FTDI modules. Some are labelled FTDI other claim to be FTDI but are CH340. Some have DTR others RST and good ones like Adafruit Friend it is selectable.

My recommendation is do not try to save a few bucks here. Spend money on a good quality FTDI adapter like Adafruit Friend.

flybysun · 17 Aug 2018, 19:54

Hi,
I'm using the mysensor lib for a while but I recently run into problems. I've some arduino pro minis running with dht22 sensors which send their data over nrf24 to an mqtt ethernet gateway.
But maybe someone can help me with this one: I have build my own sensebender-micro modules. First of all I programmed the fuses of the mega328p as follows: lfuse: 0xE2, hfuse: 0xD2, efuse: 0xFE. Then I've programmed the DualOptiBoot Bootloader to them, everything worked fine so far, I can upoload sketches from the Arduino IDE via FTDI Programmer. The Problem: When I upload the official example sketch and watch the serial monitor I just see the MySensors splash screen. It seems, that the sketch does not even run into the setup routine. This starts to make me crazy, since I do not even know where to search. If I upload other sketches (basic blinking led, serial port examples or the passive node example from mysensors) it shows that my hardware in general seems to work. When I enable debug this is the output:

Even the NRF24 connection seems to work. This is the output of my mosquitto broker when running the passive node example:

Hi @flybysun, welcome to the forum!

!TSM:FPAR:NO REPLY

means that the sensor node does not get a response from the gateway. What type of gateway are you using? Could you post the debug log from it?

If you haven't already, check https://forum.mysensors.org/topic/666/debug-faq-and-how-ask-for-help/ for the most common problems and how to troubleshoot them. (Hint: Power supply is the most common problem, the nrf24 is extremely picky)

flybysun · 19 Aug 2018, 19:37

Hi @mfalkvidd, thanks for the warm welcome!
So, tonight I'll give it another try. I soldered 1000uF above VCC and GND on both the sender and the gateway RF Links (that's all I could find here for now). Still got issues. Here are the logs from my gateway, when it starts up and receives values from my working sensor I had before:

This looks okay I guess, now this happens when I activate my SenseBender Micro:

I filled this logs into the Log Parser and found out that the Gateway receives informations on the sensor node, but when it responses it does not get the ACK from the sensor node.

May I have a faulty NRF24? I just received a new batch from AliExpress and this my first try with them.

My gateway is an Arduino Uno Board with the Arduino Ethernet shield and on top of that equipped with the long range version of the NRF24 Board (the one with the antenna).
The SenseBender is equipped with the "normal" smt version as suggested. The sensor nodes which are working right now were equipped with the smd version of the nrf-board.

I also found out that the initialization of the sensor and the gateway has a different Core initialization, different capabilities (CP). I looked through the API, but didn't find what CP=RNNGA or CP=RNONA stands for.

Any suggestions or ideas?

@flybysun information on capabilites is available at https://forum.mysensors.org/topic/7718/mysensors-capabilities-deciphering and https://www.mysensors.org/apidocs/group__MyCapabilities.html

tbowmo · 20 Aug 2018, 10:21

@flybysun

what is the "official" firmware that you upload to the atmega? If it's the sensebender micro fw, then please observe that this is meant to run with a Si7021 sensor, and not DHT22, so unless you modify things, it won't run without that sensor onboard..

flybysun · 20 Aug 2018, 11:37

@tbowmo
I have a 1:1 build of the sensebender micro, including the Si7021. Something I definetly will try tonight is to change the the radio modules with one of these I had before (and are working). I've just discovered this here:
https://forum.mysensors.org/topic/1153/we-are-mostly-using-fake-nrf24l01-s-but-worse-fakes-are-emerging

With "official" firmware I mean the Arduino Sketch which is included on the hardware webpage:
https://www.mysensors.org/hardware/micro

flybysun · 20 Aug 2018, 21:06

@mfalkvidd @tbowmo
So folks, I finally got it to work. It really seems to be a problem with my radio modules. When I change my PA module on the gateway against one of these I ordered for the SenseBender Micro, everything works fine. But I still don't understand why my pro mini with the smd radio was able to send the data to the pa module, while the sensebender connected to a smd version still didn't work.
Is there anything special on the PA Version, that I've missed? I wonder if I can live with that now, I thought the PA Version has a bit more sensitivity and gain and would be better as the central gateway unit.

mfalkvidd · 21 Aug 2018, 06:46

@flybysun the PA version draws much more power than the non-PA version (5x more if I remember correctly). If the power supply can't deliver clean power (without ripples or sudden dips), the radio will malfunction.

djbonet · 3 Oct 2018, 17:52

Hi team,
By curiosity running the Atmega328p at 8mhz down to 1.8v isn’t out of spec ?
Does it work reliable ?
Should we div8 clock speed than mesure vcc and set prescaler accordingly ?
Just by curiosity for further project I see a lot of info to not go above 4Mhz at 1.8mhz as the data sheet and other that it’s working stable even a 8mhz

Thanks all !

mfalkvidd · 3 Oct 2018, 18:12

@djbonet yes, running the atmega328 at 8MHz and 1.8V is out of spec.
Yes, sometimes running out of spec doesn’t cause problems.

djbonet · 3 Oct 2018, 19:42

@mfalkvidd
Thank you for your fast answer

mfalkvidd · 3 Oct 2018, 19:48

@djbonet you’re welcome. If I remember correctly, the datasheet diagram shows the limit for 8MHz to be 2.4V

marnej · 31 Jul 2019, 22:43

Hello
Can't compile skech .. .does anyone have updated ?

martim · 8 Aug 2020, 14:46

Is there a way to order this board somewhere else. I have ordered now 3 times 2 boards. 2 times 1 board broken and it is very hard to communicate with them and almost never reply.

tbowmo · 8 Aug 2020, 15:06

@martim

Unfortunately we do not have any other manufacturing partners, so all sensebender boards are produced by itead.

How did you confirm that the board where broken? Have you tried starting the self test in the standard firmware that the micro is delivered with?

The factory firmware is available at
https://github.com/mysensors/SensebenderMicro/blob/master/Arduino/SensebenderMicro/SensebenderMicro.ino

SuperNinja · 17 Feb 2021, 16:40

@tbowmo I am using Sensebender Micro on an ATMega328p Barebones with internal 8MHz and RFM69 working good. Since I don't have quartz connected on PB6 and PB7, I would like to use these ports. I tried from 14 to 21 but unable to flash my led (connected to PB6).
With Minicore: PB6 and PB7 are 20 and 21 respectively.
With Sensbender Micro, what are the ports? (if they exist)

keithellis · 2 Jul 2021, 16:41

Hello, really interesting in getting a few of these Sensebender Micros, but it does not seem to be available any more. Will they be coming back into stock?

tbowmo · 2 Jul 2021, 16:45

@keithellis
They should be available here https://itead.cc/product/mysensors-micro/

keithellis · 2 Jul 2021, 20:14

@tbowmo Thats great, thank you. The URL seems to have changed.

keithellis · 5 Aug 2021, 21:11

Hi there,
Just received a couple of Sensebender Micro's, really excited to get them up and running. I'm trying to compile the sample code, but I can't find a library for the sha204, I'm getting the following error:

sha204_lib_return_codes.h: No such file or directory

Any idea how I can solve this please.
thank you.

mfalkvidd · 6 Aug 2021, 06:11

@keithellis the file is in the same folder as the example sketch: https://github.com/mysensors/MySensors/tree/development/examples/SecurityPersonalizer

How did you install MySensors? How did you open the SecurityPersonalizer sketch?

keithellis · 6 Aug 2021, 19:20

@mfalkvidd Thanks for the response. I was not trying to compile the SecurityPersonalizer sketch, I was trying to compile the Sensebender Micro example sketch, this apparently also needs the sha204xxx files. I copied these files over from the SecurityPersonalizer sketch and it works now. thank you.

I think sha204xxx files should also be put in the Sensebender Micro folder. Or some directions on the Sensebender Micro page on where to get these files.

mfalkvidd · 6 Aug 2021, 20:19

Thanks for explaining @keithellis

I am not familiar with the sensebender micro but what you suggest sounds reasonable.

Is this the sketch you are using? https://github.com/mysensors/SensebenderMicro/blob/master/Arduino/SensebenderMicro/SensebenderMicro.ino

keithellis · 8 Aug 2021, 16:02

@mfalkvidd Yes, that’s the one.
