Hi everyone, I'm trying to create a custom peripheral for a payload on my quad! I want to learn, how I can implement code changes and add support for my custom peripheral. I am starting from basics, so the peripheral can control and external set of hardware and I want the status over telemetry! How can I implement this feature in betaflight and add support for telemetry as well.

FC ---> Payload (via UART)
|
|
telemetry --> Transmitter (via ELRS CRSF)

which then can be visible on the ELRS Telemetry screen, I can write the lua script for that!

Firmware: Betaflight 4.5.1
Configurator: 10.10.1
Flight Controller: SpeedyBee F405 v3

Edit: the Peripheral to be based on Arduino and communicate via UART to receive the Aux Values from Fc and return some statuses which should be shared with the Transmitter via Telemetry over CRSF (ELRS)

It depends on what type of peripheral what are you looking at?

#

So, you’re looking to send the signal to an Arduino

azure kelp So, you’re looking to send the signal to an Arduino

yes, to send signal and also get status in return!

Ok sending a signal not too hard getting telemetry and returns harder but definitely possible

#

I have not done this before, so you might not want to take all your advice from me
