Still trying to figure out if the Flight Controller can be used for a tricopter. From what I am seeing, the Timer and output mappings make it impossible since there are only 4 outputs, and they are paired up between two timers. Servos and Motors can not share a common timer.
DEF_TIM(TIM3, CH3, PB0, TIM_USE_MOTOR, 0, 0), // S1_OUT D1_ST7
DEF_TIM(TIM3, CH4, PB1, TIM_USE_MOTOR, 0, 0), // S2_OUT D1_ST2
DEF_TIM(TIM2, CH4, PA3, TIM_USE_MOTOR, 0, 1), // S3_OUT D1_ST6
DEF_TIM(TIM2, CH3, PA2, TIM_USE_MOTOR, 0, 0), // S4_OUT D1_ST1
The only option might be to remap an alternate pin like the LED output pin for the servo.
DEF_TIM(TIM4, CH1, PB6, TIM_USE_LED, 0, 0), // LED strip
Hmmmm.....
Found this from someone using another variant of the OmnibusF4SD and mapping the servo to the LED
I think the cmds would be along the lines of:
resource led none
resource servo 1 B06
