GPIO Test Demo
The GPIO Test application running on the ZedBoard takes user input to select which
push-button switch is used to trigger the timer to turn the LED on and off.
1.
Follow the screen prompts to select the push button input. One push button is routed
to the AXI GPIO peripheral (BTNU) and the other is routed to the CPU GPIO
(BTNR) through the EMIO interface between the PS and PL sections. Run the
application as many times as you wish and alternate which push button is selected.
Leave the terminal window open when you are done. We will reuse this terminal
session again later.
