Hi @willronan,

[This comment](https://discuss.bluerobotics.com/t/0-100-duty-cycle-pwm/22104/2) should be a good starting point for the configuration of duty-cycle based PWM, and links to a thorough example of setting up control of an output with a slider. Feel free to follow up if you get stuck on parts of that.

If you really want increment/decrement control via the joystick,

Note that such an approach … adds some control latency (because it is effectively ‘responding’ to MAVLink messages from the autopilot, so the normal communication latency is doubled, plus some delay from the relevant message frequencies).
