LED pin can be used to emulate 5key OSD joystick for OSD camera pin, while still driving ws2812 LEDs (shared functionality). LED pin can be used to emulate 5key OSD joystick for OSD camera pin, while still driving ws2812 LEDs (shared functionality).
See [LED pin PWM](LED%20pin%20PWM.md) for more details.
Note that for cameras which support RuncamDevice protocol, there is alternative functionality using serial communication: [Runcam device](Runcam%20device.md) Note that for cameras which support RuncamDevice protocol, there is alternative functionality using serial communication: [Runcam device](Runcam%20device.md)
