variable pwm no more servo output #109

Closed secretman28 closed 9 months ago

secretman28 commented 9 months ago

i flash the test for acessing the pwm . i nuke the rp2040 to be shure to start new. all seam to work serial connection act as usual , set all the parameter as usual and all is set when a look in the serial return

i got nothing on the servo output anymore i can set any pwmhz and nothing come out test with a ocillioscope show nothing

flash back main all work as usual

secretman28 commented 9 months ago

i test again tonight same i can get pwm out to work, i will try to look in to the code a bit but.. im not that good hahah

secretman28 commented 9 months ago

other test, the pwm command show that the pico receive the rx signal i move the throttle stick in this example

Hello secretman28, I have just tested Ver.2.8.22 again with the command PWMHZ=50,100,333 on channels 1-10, with my X20S with TD-R10 and FBUS Protocol. I get a value between 988us to 2012us on all PWM channels and the connected servos work perfectly. Greetings, Torsten

secretman28 commented 9 months ago

mmm im testing elrs can be the problem i need to chk if sbus work tanks for the help i will report back still, main work as usual all same parameter except the pwmhz

mstrens commented 9 months ago

I think I found the bug for PWM with ELRS. Can you now try version 2.8.26 (in test branch)

secretman28 commented 9 months ago

yes i will thus morning

secretman28 commented 9 months ago

cant get nothing even sbus to get out i dont have a tonne of time today but will still test more can be something i do but if i flash back main servo pwm work still need to mess more to tell

mstrens commented 9 months ago

I checked the code once more (comparing main and test) and I do not see the bug. When you have time to test, I can make a test version that should print more debug messages to see where the part of the code that are used and not used.

secretman28 commented 9 months ago

i willl test in an hour need to finish something before if you want reach me faster discord me, if not put it here i will be aware and check tonight

secretman28 commented 9 months ago

just download the test code and now all is good! on sbus on elrs etc etc can set pwmhz too ocilloscope show the hz change ans i wana say rp2040 is pretty good at getting stable signal!

this version is working for pwmhz tanks for taking the time to implement it
