hey,
I would like know if is possible to use the GPIO ports of the OLIMEXINO-32U4 with the A13 Olinuxino, its as with the Arduino Leonardo ?
thank you
What do you mean by "use"?
I think we need details of what you want to do...
connect analog sensors to the 32U4 and send the value of the sensor to the A13 and control GPIO in out of the 32U4 with the A13 infact its to control de GPIO ports of the 32U4 with the A13
If the signals are suitable it should work if you write some software.
The A13 seems rather expensive and full of features just to do it!
Be careful about grounds etc.
