zybo Interfacing external Peripherals eg. LEDs

[Allan]

Hello, 

I was earlier able to flash LEDs on the Zybo 7010 board following the tutorials. However, I am currently trying to use the Zybo 7010 to flash LEDs which are external to the board. What I am looking at here is getting a constant voltage supply from one of the ports (maybe preferably the Xadc)  to power the external LED circuit. I am having trouble getting a block design using the xadc_wiz_0 ip and the axi gpio with the zynq 7000 processor. Any information on this is greatly appreciated.

Hi @Allan,

In this situation you do not need to use the XADC IP core. You would use the same block design from the internal flash led but instead of choosing the leds in the the GPIO IP core you choose custom. Then you would make the wrapper and constrain the pins names from the wrapper in the the Zybo Z7-10's xdc here.

cheers,

Jon
