Add Two Servos to SpeedyBee F7 v3 FC

[vlamgat007]

Hi Everyone,

Is it possible to remap the resources on a SpeedyBee F7 V3 to accommodate two servos? If so can someone please help me with how to do that? This betaflight article seems to suggest that it may be possible but not sure if there is an INAV limitation. Below I have pasted in the current 7.1.2 mapping. from target.c.

Thank you!

2024/6/15 Update: Two potential configurations in INAV mixer that may work. Only down side is that with the way the timers are assigned there is no config where I can still use S1 to S4 for the motors...so instead of using the 8 pin plug between the fc and the ESC I will need to do some soldering.

Anyone know what the comment on S6 is about? "Clash with S2, DSHOT does not work"

Thanks!

DEF_TIM(TIM2, CH1, PA15,    TIM_USE_OUTPUT_AUTO, 0, 0),  // S1
DEF_TIM(TIM2, CH2, PB3,     TIM_USE_OUTPUT_AUTO, 0, 0),  // S2
DEF_TIM(TIM3, CH1, PB4,     TIM_USE_OUTPUT_AUTO, 0, 0),  // S3
DEF_TIM(TIM4, CH1, PB6,     TIM_USE_OUTPUT_AUTO, 0, 0),  // S4
DEF_TIM(TIM4, CH2, PB7,     TIM_USE_OUTPUT_AUTO, 0, 0),  // S5
DEF_TIM(TIM3, CH2, PB5,     TIM_USE_OUTPUT_AUTO, 0, 0),  // S6 Clash with S2, DSHOT does not work
DEF_TIM(TIM3, CH3, PB0,     TIM_USE_OUTPUT_AUTO, 0, 0),  // S7
DEF_TIM(TIM3, CH4, PB1,     TIM_USE_OUTPUT_AUTO, 0, 0),  // S8

DEF_TIM(TIM8, CH3, PC8,  TIM_USE_LED, 0, 0),    // LED
DEF_TIM(TIM5, CH1, PA0,  TIM_USE_ANY, 0, 0), // Camera Control

This is how I got it set up. Tested and working as expected. Resulted in soldering S5 and S6 but that was minimal effort.
