I'm working on a i.MX28 evk board and I want to read 1 byte from GPIO pins as fast as possible.
I'm workin with Linux OS and I would polling continuously GPIO pin.
Do you have any suggestion?
I can understand your meaning. I feel if you want to get to your participation, Real time OS should be selected ! Such as Real Time linux , QNX , VXworks etc.
Under common linux OS(non-real time), it is very difficult to improve more .
