I wonder if I should just put betaflight back on it, get it configured and see what works and doesn’t, just to rule some things out…
I did this hwdef - all the goku’s support bi-directional dshot out of the box, there is no separate binary.
Well, I flashed it to betaflight, tried every pin-mapping and combo I can think of: PWM on all the motors, remap servo to unused rx/tx, traced the extra pads on the bottom, reassigned the neopixel pad… Nothing no servo pwm signal at all… As a last resort I sent an email to the Flywoo support guys, but I am not super hopeful.
I am using a different flight controller (F405-Wing), so if the main problem in the current thread is hardware, my experience is out of question.
Per the discussion Max and I had, I am switching to an F403 variant, I guess I’ll just shelf the goku and use it on my next quad.
