Hi,

I need to switch led On/OF form autopilot, in every 5 min (without radio).

If i managed to change code(arduplane 2,65) to make: relay_on() relay_off() every 5 min , then what PIN dose that correspond to?

Or how can i make costum PIN output? (for relay, or optron)

code, relay

One way would be to use jD-IOBoard that already supports MAVLink to driver relays and other things. I think I will make driving relays optional on next firmware for it. IOBoard have full support for ArduCopter and MAVLink protocol.

jD-IOBoard v1.0, MCU controlled IO Board for driving LEDs, Relays, Servos

You can easily change that 3 functions to alter the pin of your choice. Then just upload your custom firmware to APM.

Hello Mell,

I found this in the system.pde:

#if CONFIG_RELAY == ENABLED
DDRL |= B00000100; // Set Port L, pin 2 to output for the relay
#endif

This is Digital pin 47

In the Eagle files I could find any connection to this pin !

I'm afraid this connection is cancelled on the APM2 and APM2.5 boards !

I think it's easier and more safe to use a Arduino Nano board or similar.
