Hi
 
I have an over fire on a summit board, and I would like to use the GPIO's as an input to a signal.
 
I know how to write, compile and execute code on the gumstix, but I have no idea how to refer to the GPIO's and read signals or send signals through them.
 
Could anyone please help, and maybe send a code example of how to do this?
 
Thanks
 
Nick
