PPM output issues - Githubissues

RobotSub commented 2 years ago

I don't think the PPM output is working correctly even though the notes indicated that it was fixed.

Test sequence (repeatable) for FS-I6X ⦁ Load latest factory I6X firmware via DFU / STM Cube programmer (x08000000/x20000) ⦁ Power on ⦁ Confirm correct 8 channel PPM signal on trainer port connector - Yes ⦁ Load OpenTX I6X 1.7 English firmware (openi6x_1.7.0_en_220912.bin) via DFU / STM Cube programmer (x08000000/x20000) ⦁ Power on. Bad EEprom data warning, EEprom formated. ⦁ long press OK, model 01 highlighted ⦁ short press Bind, setup 2/11 displayed ⦁ press down repeatedly to Internal RF Mode ⦁ Ok, down, Internal RF Mode now OFF, click Ok ⦁ press down to External RF Mode ⦁ Ok, Up, now PPM displayed, Ok ⦁ Confirm correct 8 channel PPM signal on trainer port connector - Yes ⦁ cancel, cancel, now at top menu ⦁ confirm update box is not shown (I have also tried this sequence doing a save all) ⦁ At this point I still have a good PPM signal but if I power off and power on there is no PPM output signal ⦁ I now confirm that all of the settings were saved, all ok, also confirmed that trainer mode is Master Jack, still no PPM output ⦁ Go back to External RF and select CRSF, the CRSF serial output (from internal pad) is correct - Yes ⦁ Power off and power on and the CRSF output is still ok - Yes ⦁ Go back and try to adjust settings for PPM, no PPM output.

Notes: I have also tried with openi6x_1.7.0_elrsv3_en_220912.bin. To get the PPM output as above it is required that I first load the factory software then load the new software.

So you have to toggle PPM out off and on to make it working if i understand the issue correctly.

What was the last version it was working correctly for you?

Thank you for the response, I will do additional version testing and report back. Is this the best spot or discord or ?

ajjjjjjjj commented 2 years ago

It's a bug so it's a perfect place to report it as an issue.

Thanks again for your response. I have checked multiple versions of the code and they act the same so perhaps it's not a bug (?) but I have spent several days playing with this and read everything online I could find so I seem to be at a stopping point , getting to my problem is simple compared to above list, the list below is fully repeatable after loading version 1.7 , any pointers on how to proceed appreciated.

go to HARDWARE menu and do a factory reset
long press OK, confirm Model 01 selected, go to SETUP
change External RF Mode OFF to PPM and the PPM output is correct on the rear connector
click OK, Click cancel, cancel to go back to the top level, PPM output is still fine
power off, power on, PPM output is missing although PPM is still displayed for External RF Mode OFF
?

There is a workaround to toggle PPM output to make it work after restart: https://github.com/OpenI6X/opentx/issues/155#issuecomment-1044572241

I believe it could be broken with "PPM in" introduction, so right in version 1.0.0, because that's where logic has changed.

Thank you I will play with the work around a bit more, I wasn't successful with it just now. It you ever need help pre-testing releases let me know.

Hi @RobotSub, can you let me know how it behaves on this one:

Edit: removed due to found issues.

I will try out this weekend and report back (I am on Holiday travel during the week)
