oXs Ver.1.1.7 ADS values A0-A3 in FV Terminal

[Satcomix]

Good morning Mstrens, One day no time and already 4 versions further. I am currently testing Ver1.1.5 with FrSky X20S S.PORT. With the "FV" command, I noticed that RPM is not displayed in the terminal. The display now shows 21 sensors from the oXs_RP2040 plus 8 sensors from the TD-R10 receiver. The values ​​from the ADS1115 are displayed with FV, but not in the handheld display, not even with DIY sensors. Greetings, Torsten

Did you already tried to upload again the version 1.1.9 from github without making any change. Normally there is no need to erase every thing and so you do not have to reenter your parameters. Perhaps you made typo fout somewhere without noticing it. That the reason why I propose to start from a new download from github.

[Satcomix]

When i put the original 1.1.9 on the board , i dont see any voltage to A0-A3 and when i make the change to MV4096, i have no Telemetry but SBUS is blinking green. PlatformIO Error???? By version 1.1.9 there are many warnings of EMF Button, but i can make a build and upload.

[mstrens]

When you put the original 1.1.9 on the board, did you compiled it your self or did you just make a copy/paste of the version I put in uf2 folder. If you did not do it, I suggest a test with the version I put in uf2 folder.

The warnings about EMF button should not be an issue. This part of the code is currently compiled but not activated.

Perhaps make also a test without connecting oXs to the SBUS (because it is the way I tested it on my side)

[mstrens]

I really do not understand why your oXs seems replies to reply to ENTER command but not to FV command. Does it reply to the "?" (help) command?

[Satcomix]

I will explain the way i do it every time,when a new version is out in GitHub. I go to CODE and make a .zip Download. Than i make a new folder with the Name of the version. I extract the new version in that folder and make a copy to the Projects Folder from PlatformIO and copy and replace the old -test folder. I think thats the right way i do it.

[mstrens]

The way you do it should be OK. Still can you try (as test) to just do a drag and drop of the file uf2/APPLICATION.uf2 that is part of the zip.

[Satcomix]

I do not understand, when i put the .uf2 from my fresh extracted folder to the board, i make a drag and drop, or what do you mean?

[Satcomix]

I make a download from Git of the APPLICATION.uf2 and copy and paste it to the board.

[mstrens]

You have to press the "boot" button of the RP2040 when you apply the power on. So the RP2040 enter automatically in bootloader mode and the PC see it as a USB drive. You can then do a drag and drop (or a copy/paste) from the uf2/APPLICATION.uf2 file to this drive usb drive.

This automatically upload the file (flash) and the RP2040 restart automatically.

[mstrens]

OK I was to late with my last reply. So now, you get a reply to the FV command but they are all 0mv.

[Satcomix]

Thats the normal way a make it 100-200......... times the last weeks. or you press RESET and hold the BOOT Button to get the RPi Folder.

[mstrens]

Yes you can also press RESET and hold BOOT. Are you sure that your wire between A0 and VCC (3.3v) is correct (good connection?)

[Satcomix]

I think i make some more tests with my other Boards and the 1.1.5 and 1.1.7 versions and order some new ADS1115 from Berrybase or Eckstein. I will have a look to my Laptop, if there was a update, and i will look to PlatformIO. I can't think of anything else to solve my problem at the moment. For this time, i think we should close the issue. You get the right results and Pierre also, i think. Thank you for the time and work.

[Satcomix]

I have tested my boards several times, i dont like breadboards and thats why i like only soldered connections.

[mstrens]

I am not sure that Pierre get the right result. I think he does not make tests with the last version.

I can only say that It seems to work on my breadboard.

Anyway, you should get the same result if you compile your self or if you use the version I compiled.

[Satcomix]

For this day i must close with the tests, tomorow morning i will do new tests with other boards to test the firmware, and make some new builds with PlatfrmIO. Have a nice Day, see (write) you tomorow. Greetings, Torsten

[Satcomix]

Hello Mstrens, Next day, next test :-) I have now tested all 9 boards, the same result everywhere. Yesterday I read a lot about ADS1115 and what problems can occur with "supposedly genuine" ADS1115 (CN clones). I tested my ADS1115 with different scetches on Arduino Nano. Everything worked and I couldn't find any possible errors. I have also ordered two new ADS1115s, they will arrive next week. It seems to me that there is some problem with the evaluation of the register of the internal multiplexer from the ADS, since only one value is displayed, usually that of A1/Port2. Have you had time to find out yet? I don't know what to do anymore!

[mstrens]

I do not understand why it works on my side and not with your board. do you now get the same result when you compile your self? If yes, you can try to increase the delay oXs wait to get the conversion. This is in this line if ( ( millis() - ads_MilliAskConv ) <= (uint32_t) ( ( 0x88 >> ads_Rate[ads_idx][ads_CurrentIdx]) + 1) ) return false;

Yo can try changing "1" by e.g. "100". So having: if ( ( millis() - ads_MilliAskConv ) <= (uint32_t) ( ( 0x88 >> ads_Rate[ads_idx][ads_CurrentIdx]) + 100) ) return false;

Do you know which lib you used when you made the test with Arduino? So library does not use a delay between requesting a conversion and reading the result. They test a flag in the ADS1115 to know if the conversion is done. Perhaps some ads1115 require more time to perform the conversion.

[mstrens]

In your yesterday tests, I noticed a strange behavior: You got some "Attention......" messages saying the the core 1 did not performs the setup within some delay (2 sec). On my board, I do not get this message because the setup on core 1 is done within a little more than 1 sec. In the last version I made yesterday, I made a small change: oXs does not print a lot of those "Attention" messages but only one. Furthermore oXs prints also the delay it takes (Setup1 takes xxx usec) where xxx should be the delay (valid only when it is less the allowed timeout (2 sec). What is the xxx value you get? Note: when I want to be sure that the PC displays all messages sent by oXs at power on I usually activate the DEBUG option in config.h file. This forces oXs to wait a few sec before sending the first message and allow the USB/SERIAL connection to establish.

Hello Mstrens, the Arduino libary is ADS1115 from Rob Tillhaart https://github.com/RobTillaart/ADS1X15/releases

This day i can make new builds with PlatformIO and everything is ok, also when i go to Terminal with FV. I think trough the whole tests yesterday there was a fail in Platformio or my Laptop. processing cmd

Input is A0=1020mV, A1=1596mV, A2=2035mV, A3=1042mV

[mstrens]

I also had sometime an issue with platformio. I had to close vscode and re-open it. I do not know why. So, it seems that your ads1115 does not perform the conversion withing the expected time. I checked the lib you used and this lib does not use a delay to wait for the end of conversion but read a flag in the ads1115 register. Perhaps you can now try to reduce the 100 with a smaller value e.g. 5 to see if it is still OK.

[mstrens]

I put on github a version 1.1.10 that wait 1 msec more for the end of conversion before reading the ADS1115. Furthermore, after the expected delay, it checks now that the flag saying that the conversion is done is really set. If not it wait some more time. I hope that this version works for you too.

In sport a message (for a field ID) is sent only when there is a new measurement for this field ID. depending on your setup, it can take several second between 2 measurements. E.g. a ADS can only perform one conversion at a time. So if you ask for 4 measurements, oXs will make 4 conversions, the one after the other. The delay for one conversion depend on the rate that your requested. Furthermore If you ask for an average on 50, it means that oXs will have to make 50 conversions (on this pin) before having a new value. So, you have probably to increase the rate and/or reduce the Average on and/or the number of pins being measured. I expect that there is a message telemetry lost when the handset doe not receive a sensor withing a delay of x (2?) sec.

[mstrens]

If you want to know the time (msec) it takes to make a conversion, you can add a line of code in ads1115.cpp.

After line if ( ( adsConfigMsb & 0X80) == 0) return false; // conversion is not yet done

You can add this line printf("conversion ads115 in %d ms\n", (millis() - ads_MilliAskConv));

So you can compare it with the value set in your config.h and you can see how "slow" is your ads1115

Now, everything is fine. You should use in ADS_Rate max. 9ms, better 5ms and use max. ADS_Averraging=20, I use 10. No telemetry sensor lost since 10 Minutes. Thank you very much.

I made some more tests, and can`t find any issue. So i will close this "monster-post" and have to say thank you for the time and work. Greetings, Torsten
