Quad FC for Airplane: Pinout for Mamba F722

[obucklin]

Hello,

I am trying to set up my Mamba F722 as an airplane FC, but I can't seem to find out what pins/pads to use for the servos. I realize that resource mapping is not an option, which would make things way easier. I know which pins on the microcontroller correlate to which pads on the board itself from looking at resource in the BetaFlight CLI. In iNav CLI, there are no servo outputs listed when I run resource. Does that mean I cannot use servos at all with the board? On Github, I have found the .HEX file for the board, but I can't locate the source files, which I thought would help me determine the pinouts. Any help would be much appreciated!

Thanks!

OK a bit more detail...
I found the Mamba F722 target and it contains this definition:

`const timerHardware_t timerHardware[] = {

    DEF_TIM(TIM11,  CH1,  PB9,   TIM_USE_PPM,       0, 0 ),     // PPM IN

    DEF_TIM(TIM8,   CH3,  PC8,   TIM_USE_MC_MOTOR | TIM_USE_FW_MOTOR,  0, 0 ),     // S1_OUT – D(2, 4, 7)
    DEF_TIM(TIM8,   CH4,  PC9,   TIM_USE_MC_MOTOR | TIM_USE_FW_MOTOR,  0, 0 ),     // S2_OUT – D(2, 7, 7)
    DEF_TIM(TIM1,   CH1,  PA8,   TIM_USE_MC_MOTOR | TIM_USE_FW_SERVO,  0, 1 ),     // S3_OUT – D(2, 1, 6)
    DEF_TIM(TIM1,   CH2,  PA9,   TIM_USE_MC_MOTOR | TIM_USE_FW_SERVO,  0, 1 ),     // S4_OUT – D(2, 2, 6)

    DEF_TIM(TIM2,   CH2,  PB3,   TIM_USE_LED,       0, 0 ),     // LED_STRIP – D(1, 6, 3)

};`

I am guessing that it normally only supports 2 servos and 2 motors. My airplane is simple and would only use 3 analog servos and an old-school ESC that also runs on PWM. Those pins are the four motor pins for quad setup, and I would love to use the ESC wiring harness header to connect the servo signals. So three questions I have are:

• can I change the PC9 to be a servo output?
• do I need to change S1_OUT at all for the super basic ESC?
• Can I/how do I make the HEX files if I change these parameters?
  Thanks!
