Hi
I did get 20 of the original boards made but never made the dlg version because I didn't have the need.
Are you interested in making some?

Re: custom PCB
So after a bit of doing here is a new revision
MS5611 is turned 90 deg
I don't have any space left for mounting holes sry
Added two additional ADC pads
All pads are now on the same side of PCB as 1mm test pads
PCB is even smaller 22.6x13.5mm

Re: custom PCB
Here's another update with the decoupling coil and pads for TWI sensors
I didn't implement 4 pads for NiMh battery because i think it's useless to monitor individual cells.
No NiMh battery Pack has a balancer connector AFAIK

Re: custom PCB
Hi I updated the schematic and board pinout on Sport and batt conector are now the same and there are jumpers for 1S and 2S configuration Concerning the recommendation from Tempo I'm not quite sure So you want a 10uH and 100nF from Vcc to AVCC right? Also all the pinheaders should be replaced with t...

Re: custom PCB
Found it myself
It was exactly because of the issue above
changed line 558 in oXs_out_frsky.cpp to
SendValue( FRSKY_USERDATA_VFAS_NEW , (int16_t) (voltageData->mVolt[VFAS_SOURCE - VOLT_1 ].value/10.)+2000);
Now it works nicely

Re: custom PCB
Hi
I just tested one of the sensors on D-Series receiver.
It works but the VFAS voltage is displayed wrong
Instead of 22.65V it display 206.72V
I think this has something to do with:
https://github.com/opentx/opentx/issues/2607
Ideas ?

Re: custom PCB
Hi
I just commented out the //#define DEBUGASERIAL
and enabled the voltage sensing pins again in the oXs_config.h
tried it and it works perfectly
Thanx for adaptation and support

Re: custom PCB
Hi
The new version works like a charm on my board with RC oscillator
Attached I have the logic trace with S.Port and A0 traced.
Of course no cell voltage measurement at this point

Re: custom PCB
So after a bit of waiting here is the dlg version of my board
Have a look at the pdf for details
Gerber files are uploaded as well.
Board dimensions are 13,5x25mm
How's this for a small board?
Features vario and 2S lipo measurement

Re: custom PCB
Did another capture where one data packet came through
Ids are not changing anymore
But the date is coming very seldomly
Timing seems ok but I guess the openXsensor doesn't properly see the requests and therfore doesn't answer regularly

Re: custom PCB
Hi
Sure enough I have a salea logic
Attached is the captured file
As you can see the sensor is not answering at all (which is what I expected)

Hi I tried a basic configuration with old and new code on my pcb and the old code works while the new code (new sport branch) doesn't however on the 16MHz arduino board both versions work just fine. Now I don't have a 8MHz Arduino board with the resonator populated so I can't tell whether the 8MHz c...

Re: custom PCB
Hi
In the meantime I took an arduino mini pro board running at 16MHz
Here the code works fine
Can it be that the new code require 16MHz clock frequency?
Or should it also work with a more stable 8mhz clock ?

Re: custom PCB
Hi I just flashed the new version and now I'm getting some telemetry data. But it is irregular and the IDs even for the same information keep changing. I was wondering maybe this has something to do with the fact that I'm not using an external oscillator on my board but rather the internal RC oscill...

just tested the new code
on a board with soldered ms5611 chip.
Doesn't work either. No telemetry reaction whatsoever

Re: custom PCB
Thanx
If you need me to test anything please let me know
Also I can try with a board that also has pressure sensor onboard

and it doesn't send any telemetry data
I've attched my config file
Did I overlook something?

Re: custom PCB
Understood
I will check which variables have to be changed to make the autodetect.
Is there anywhere in the code that is good to implement the autodetection function.
In which .cpp file ?

Re: custom PCB
Hi Thx for the answer My measurements were done with a 3S lipo connected to cell1,cell2,cell3 The reported voltages in the AccX,AccY and AccZ field look fine (3917,7815,11718) Which I guess translate to 3.917V, 7.815V and 11.718V Which is correct. However the voltages reported in the Cell field seem...

Re: custom PCB
Yeah that was the idea Now I chatted with the creator of the diy rx software and he tells me that the telemetry protocol is not fully reversed yet. So I will send him one of the above pcbs so he has a telemetry sensor with which he can check the protocol. He says there is enough space left in the at...

Re: custom PCB
Hi
I was thinking about integration with the receiver
Since the FrSky protocol was reverse engineered
http://www.rcgroups.com/forums/showthread.php?t=2124647
I was thinking about integrating both for minimal space.
Not sure how well this would work though

what would be on the wishlist for a DLG version?
In the meantime I've ordered PCBs for my version to check out if everything works
I'm still unsusre about the resonator

Hello guys
I went ahead and designed a custom pcb for openXsensor
it includes the atmel mcu, the ms5611 pressure sensor and the voltage dividers for lipo voltage monitoring
Have a look ant tell me what you think and if I have overlooked anything.
Design is in Altium and I will upload gerber files
