Problems with singlecopter mixer

KioLiex opened this issue · comments

In the Baseflight GUI the servo outputs are displayed correctly, but all of them are not outputted to a pin. Only the left and right servo are avalible on pin 1 and 2, the motor output is on pin 3. The front and rear servo are not avaliable on any pins.
I have tested in both PPM input mode and normal mode and tried many different combinations of modes, and selection. Nothing can make it work.

if this worked, servo outputs would be on motor pins 3..6. patches welcome.
it did work before.

Just tried with the stable version from the 1st October. Still Left and right servo on pin 1 and 2. Motor on pin 3. On pin 4-6 the Oscilloscope shows a signal that looks like the one for the motor, but it is at a stable 1ms (1000) in pulse width.
Hope this helps the depugging.

I want to give this issue a bump because I am getting the same results as KioLiex. Servo signal is coming through on pins 1 and 2. Pin 6 already burned up one of my servos. It's as if the signals are mapped using the quad with servo gimbal. Sercos on 1 and 2 with motor signals on 4 through 6. This issue pretty much eliminate the possibility of using the singlecopter profile with Baseflight until it is solved.

Does anyone plan on fixing this glitch? I wish I had the coding skills to do it myself, but I must humbly rely on the expertise of others.
