💬 Roller Shutter Node

[tonnerre33]

Hello,

The PCB order link is for nrf24 or RFM69 version ?

Edit :

omg, i see the answer in the first page ^^ it's for RFM69 version .

When will you give the link for order PCB with nrf 24 ?

[tonnerre33]

Hello,

Where can we found the program (.ino) for this board ?

Thx

[Takero]

Where can i find the example sketch?

[Fabien]

There is no official sketch avaiable at this moment. And @scalz is working hard on RFM69 ... I began yesterday to write a new sketch, I will publish in few days (weeks ?).

[scalz]

Why do you want an example sketch ?
hmm..my precious sketch :stuck_out_tongue:
@Fabien is right that's quite busy days :)
I didn't published it yet because i prefer release when it's polished as i like..
Well, as Fabien is a betatester ;)
i've published a pre beta version! on my git https://github.com/scalz/MySensors-HW/tree/development/RollerShutterNode/FW/MyRollershutter

BUT i'm actually busy so i won't have time for support on setup. i think it's enough documented for the moment.
I prefer to tell this than giving hope..better like this. I learnt this from a smart guy recently :pray:

That said i hope you will have fun! and i will try to update as i can..you've not seen the new version of this board :yum:

[Takero]

Hey, no Problem :-)

I just ask for it, as you write it is in the examples folder ;-)

Thanks for the pre Beta, i will work on it :+1:

[tonnerre33]

@scalz Thanks for the pre beta sketch.
i have searched the sketch many times in the example folder too :) But no examples folder find ;)
I have posted some pictures of the pcb here i fyou want to see:

Hey Scalz, u have forgotten to connect the CSN - Pin in your PCB file for NRF24 ;-) I just solder a bridge between NRF Pin 4 and R14

[scalz]

@takero
thx for reporting!
i'm using rfm69, argh. i will take a look asap.

[Takero]

Yah, i know, take it easy this is an minor bug :-)
Your misstake is in the schematic, your wire on the NRF24 CSN-PIN is unnamed.

For feature Update, it is advisable to plug an ELKO ~400-500uF near the NRF24 Power, i have reciving problems whith "RF24_PA_HIGH" but i need hight for the distance.

[scalz]

@Takero

But it was named! or the pullup resistor would not be wired, and it was also present on atmel.. and no airwire, weird!
well, i think it happened during converstion to nrf24.
Hopefully the pullup resistor is just near the radio!

Is RF24_PA_HIGH available for nrf24 smd, i thought this was for High power nrf. i'm certainly wrong..I've no problem with rfm though.

I don't think i will do more, unfortunately, I mean in this case, it's sort of double job, and i'm using rfm69.
but when i can, i put rfm69 and nrf footprint (i have a pcb not released like this, not a shutter node).

Now it's updated :) rev=1.3a for nrf
See you soon

[Takero]

One question: what are your fuses settings for Optiboot? Dit u use the external 8MHz Clock?
Can you confirm:

L: 0xEE
H: 0xDA
E: 0x06

[Takero]

@scalz Yes, the resistor is very close :-)

In my .sch the wire is not named ;-) But anyway it works :+1:

[scalz]

@Takero

What the ??
Are you using Eagle 7x ?? I'm still using 6.5..when it works i don't change if no need ;)
but dooo! In my version i see the signal..i think this is sort of very exotic bug case and i got in my face lol

Weird, hein !
no matter thx for reporting, good to know i'll remember or update, we learn from our errors as we say :)

[Takero]

@scalz
Yes 7.5. Hey it was an "easy to solve" problem :-D

. . . maybe an eagle bug

[scalz]

easy to solve when you've eagle 7.5 ahah

For fuse&bootloader, you can use OTA howto, that's the same : https://www.mysensors.org/about/ota

[Takero]

@scalz Are you sure about the Fuses? 0xE2 is normal for int. clock?! Or i am wrong?

http://eleccelerator.com/fusecalc/fusecalc.php?chip=atmega328p&LOW=E2&HIGH=DA&EXTENDED=06&LOCKBIT=FF

[scalz]

yes this ok, i'm using this for most of my nodes.
And your link shows that it sets internal rc.

[Takero]

Ok, Thanks

[Takero]

Hey Scalz,

my prototype of your RollerShutter works well right now. I have add an Capacitor (470uF) near the NRF (it is realy needed! otherwise OTA CRC Fail, lost packages)

I have a litte bit trouble with the Current Sensor or the calculation of this.
I Used 2 60W Bulbs, if i PressDown or UP the Power Value increase up to 350W and need a loooooooonng time to decrease. round about 1W per sec.

Is this normal? In my opinion not but maybe my ASC is defective? I use a modification of your pre-alpha Sketch
