Multi-module 1.2 Board on DEVO 10

Hi all,

Following this tutorial and the vidéo from SeBy DocKy
bitbucket.org/PhracturedBlue/deviation/w...ing_the_Multi-Module


I have first upgrade my devo10 with V5 Deviation
After the soldering job done, i have installed the devo programmer for devo10
copy the hex file in the root of my tx
create the hardware.ini like that
[modules]
; there is no need to enable the cyrf6936 module unless
; it is wired to an alternate port. It is Enabled automatically otherwise
enable-multimod=A13
; enable-cyrf6936=B12
; has_pa-cyrf6936=1
; enable-a7105=S1
; has_pa-a7105=1
; enable-cc2500=S3
; has_pa-cc2500=1
enable-nrf24l01=S402
has_pa-nrf24l01=1

I have for the moment only the nrf24l01 with an antenna.

All is ok but now, when i switch on my Devo10 i have only this message :
****************
Found AVR: 0b911e53
hex: 338bytes
6 verified
****************
i try without the nrf24l01 and deactivate in the ini file, but it's the same.
i tested with a multimeter all the solder and check the good place.

What the problem ?
What should i see after this screen ?
Thank you for your help

You need to FLASH the ATtiny micro-controller with the proper hex file via DfuSe, not copy the hex to the Tx.

Thanks a lot for your answer but i think i didn't explain this very well

I put the file "avr.hex" in the root of my TX and flash the ATtiny24A-PU with DFuse 2.31 and the file programmer-devo10.dfu. flash was a success.
i have create the hardware.ini above in the root of the tx too.


is that ok ?

I would like to fly with my Super CP during my pause at work, so i flashed the V5.0 deviation firmware.
When i switch on the TX it said me, multi module not found .. so i re open my tx, put in the MM and now it work.

Nowhere it is said that we must re flash the deviation firmware, but is it the next step after the screen above ?

thx

Hi guys,

I use mm v1.2 for a couple of years now. It works very well, but sometimes (1 of 10), i've the message missing module or missing cyrf. I need to shutdown and power on again, and it works.

So yesterday, i re-done all the soldering job with good silicone wire (i thought it come maybe from the stiff dupont wire) and it's the same.

I use only the CC2500+pa+lna chip.

How can i resolve that ?
Thx

Had the same problem with my 10 with a mm, but I had all 3 modules installed. This is almost certainly a power issue. The power system for the 10 doesn't quite put out enough power for the power on surge of all three modules, and every once and a while one won't have initialized when deviation comes looking for it.

You might be having the same problem, though it's less likely with just one extra module There are two things to try:

1. Take out the mm, and just wire in the CC2500. That will cut the power usage, and may solve the problem.
2. Buy a 3.3Volt regulator,and connect MM power to that instead of the PCB. I used an LM1117T-3.3.

Not clear it's the problem, but switching to just the CC2500 instead of the MM should help if it is.

Thanks a lot for the reply, i supposed something like that.

With the LM1117T-3.3, i need just connect the left leg to my 3s lipo the middle leg to ground and the right leg is the 3.3v to the MM ?

Is there any range difference between the MM and the 4 in 1 ? (think no)

That sounds like the correct connections - I don't have it in front of me. I'd connect the 3.3V line after the power switch and not directly to the lipo, so shutting it off will shut off the MM as well.

Differences in range should be minimal, and could go either way. There's no fundamental reason they should be different, but different versions of the various RF modules might be slightly different. Nobody has reported any issues with the rf on the current version of the 4-in-1 (the first version had some issues, but they've been fixed for a while now).

Oh yes .. you are right. must find a 12v point ok.
Thank you for help !

Hi !

I have something like dropout when i fly.
It start a few month ago, and all was good during 3 or 4 month and last week it start again.

I loose control 1/2 sec and it come back.
I put the datalog.bin (rename in .ini for uploading)

If someone can please look at this file and tell me if there is a problem with my DEVO.

In the log, the problem appear 30sec max before the end.

Thank you.

Is there any .exe program to decode the datalog.bin ?

I found some python script, but i don't know how to use it.

Help appreciated.
Thx
