hello,

 

I haven't the i.MX53 Quick Start Board, yet.

I was reading the "Hardware Reference Manual for i.MX53 Quick Start".

I wish I could follow objects optically, thanks to a camera, and catch them...

I would like to use the extra mgpo of the expansion port: 12 MGPO as outpout ports  and 12 MGPO as input ports.

I have never used linux. Does the linux OS drivers provide facilities to generate signals through those ports? maybe i'll have to program in assembly the needed functions to generate them?

 

 

ps: is their some references manuals, or "how to" somewhere?

sorry for my poor english.

Best regards.
