@RJ_Make
That certainly is possble, but there is already an excellent SI7021 on board (temperature AND humidity), so why would you need it?
In any case you can connect it via de exposed pins.

RJ_Make

@GertSanders Thanks, It would be used for remote temp. sensing in a Ref/freezer/aquarium.. etc.

GertSanders

@RJ_Make
Certainly possible, check the examples.

Hello,
is it possible, that the Sketch posted here, does not work with the MySensors libraray V2.0? There have been removed many libs, (SI7021, sha204, RunningAverage), which are used in the Sketch "SensebenderMicro.ino" V01.4.
I had a little bit trouble last weekend, to get it run.
I switched back to Mysensors lib 1.56 and used the expamle Sketch "SensebenderMicro" which was included in this lib. Then it worked.
But thanks for this Great Projekt, and this great Board Sensenbender Micro

@Saimen

External libraries (and examples depending on them) have been moved to a separate repository https://github.com/mysensors/MySensorsArduinoExamples.

This was done because we can not have the external libraries in the main repository now that we are in the arduino library manager.

Saimen

@tbowmo Thank you very much for your response and explaining.

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

@tbowmo

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

@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.

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

@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...

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

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

I'll update the example.

Thank you.

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

tbowmo

@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

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",

  },

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

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

@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

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