Multiple ttl streams

David

Now you can control the autopilot from ground via ethernet-ttl converter, but is it possible to use another input GPIO for example to control onboard instruments?

David It should be possible to control GPIO pins without any problems. The most easiet way would be to run a Node javascript server on your PI, and then you could just start a webpage (just type the IP adress of your PI in your web browser) with button or whatever you need to set the GPIO pins.

There is alot of pre build packages out there, so this should be strait forward.
e.g https://www.npmjs.com/package/pi-gpio

Gpio is still free in the case of ttl converter and probably you can use it for something else. Question is : is this possible to run additional serv2net instance or someting similar and setup it to be working with gpio at the same time I think.
