EMIO PIN number

Former Member
Former Member over 7 years ago

Hello, today I wanted to control four EMIOs (2 inputs and 2 outputs) for two LEDs and  two Buttons. The LEDs are lighted through XGpioPs_WritePin functon with number 54 and number 55 GPIO. But the pin number of another two input pins are not found. Their pin numbers are not assigned directly behind the first two GPIOs (54 and 55).  In which file I can get the information? Thank you!

    Hello Nan,

    Please see the "ZedBoard Master XDC Rev C/D v3". There you will be able to find the constraints needed to connect up to the PL LEDs and Buttons.

    Thanks Josh,

    yes, as your suggestion I set the pin assignment from I/O planning in VIVADO, and I connect the four GPIOs to the two leds and two buttons via EMIO.  In SDK  XGpioPs_SetDirectionPin(&psGpioInstancePtr, 55,1) , where the second parameter set to 54 or 55(Pin Number in GPIO) can be used to control two input leds. However, if I want to control the two input GPIO for buttons, which PIN Number should I set?
