We are starting an FPV racing series and need a way to see our lap times in our OSD with goggles on.
We want to:
- push a button on our tx that will send a pwm trigger to the rx
- have the output of the tx channel signal wire go into an Arduino digital in
- where we do a pulsein, then do some timer functions
- output the lap time via a mavlink instruction into an existing text field like call sign.
Can anybody provide a link to a sample Arduino snippit that communicates a mavlink command?
