Servo outputs on SpeedyBee F7V3 #10350

Hello! How to use servo output on SpeedyBee F7V3 on INAV 7.1.2?

When i use timer outputs like this image

My resource is fine: A15: MOTOR1 OUT B00: FREE B01: FREE B02: SPI_PREINIT CS B03: MOTOR2 OUT B04: MOTOR3 OUT B05: FREE B06: MOTOR4 OUT B07: FREE

But when I try to use servo output for M5-M8, it become something wrong. I set timer3 for Servos, and Add 3 servos, like this: image

And then i look at my resource: A15: MOTOR1 OUT B00: SERVO7 OUT B01: FREE B02: SPI_PREINIT CS B03: MOTOR2 OUT B04: SERVO5 OUT- WRONG! It must bee Motor3 outputs! B05: SERVO6 OUT B06: MOTOR3 OUT - - WRONG! It must bee Motor4 outputs! B07: MOTOR4 OUT

When i try to spin M3, in really spin M4. Because M4 is on B06 in really When i try to spin M4, no motor not spin

After set timer3 for servos, the B06 set MOTOR3, and B07 set MOTOR4 automaticly. Why it is happened?? How i used servo on FC?

Unfortunately, the hardware does not allow for easily mixing servos and motors for quads, if you want s1 to s4 to be motors 1 to 4.

Due to how the stm32 hardware works, outputs on the same timer need to be all motors or all servos.

You can either resolder your esc to follow what you see in the mixer tab, or get a different flight controller.

Thacks, I solder my servo on PWM output on TBS crossfire nano, it's simple then resolder esc
