Help with Sbus Servo on F7 Flight Controller

[kd0aij (Mark Whitehorn)]

You could use a serial port for sbus out, as you tried to do plus an Sbus to PWM converter as I did here:

E-Flite Convergence with PixRacer and SBUS output

Previous conversions of the Convergence to ArduPilot have used the Pixhawk1 flight controller (E-flight converge default file, E-flight Convergence demo in Hokkaido), but the airframe is rather small, and a PixRacer fits more easily. The PixRacer has only 6 PWM outputs, and the Convergence needs 7 (3 ESCs and 4 servos). But the PixRacer does have a spare UART in typical configurations… and a UART can be used for SBUS output with capacity for up to 16 additional PWM outputs. Onboard video of h…
