Navio2 external status led and beeper

[liudmila.slepova]

Hi Pat,

Welcome to the community forum!

It should be possible to connect an external LED over I2C port that will duplicate the main LED by default. However, it might require some tuning of ArduPilot to set it up.

Regarding the buzzer, please check the answer from George in this thread:

Is there diagnostic sound using NAVIO2? Better way?

There’s a LED reserved for this kind of usage. Raspberry Pi has an audio jack, so you can hook up speakers and write a simple DroneKit script that will parse the system’s status and play a tune of you choice when somethin’s up. You can also connect a buzzer over I2C and build ArduPilot with the needed support. Just add ADD_BACKEND(new Buzzer()) in here.
