💬 Roller Shutter Node

[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

[scalz]

hmm. i didn't have 1w/sec.. perhaps acs.. i've already got a few defective. i'll check a bit when i'll have more time, too much cooking.
In case you can set default define duration, and this works well then.
But looks you got it! Great to hear it though :)
