How to use GPIO ports?

Question asked by Giulio Giovannetti on Feb 2, 2017

Hi everybody,

I have developed a function on the TWR-K65 development Platform and now I need to measure its processing time.

I think that the best way to do this is to set up a GPIO signal before the function to start and turn off the signal once the function has been completed. Monitoring this signal with an oscilloscope I will get the processing time I am looking for.

Is there any tutorial I can follow about switching on/off a GPIO singal on the TWR-K65 Platform?
