I have a 12 pin PMOD interface on my Nandland Goboard FPGA and I would like to turn on an external LED with it.
I can do it on my using pins 5 and 6 which are GND and VCC but I can't figure out how to turn it on using one of the pins controlled by the FPGA. Do I hook the LED to ground and one of the output pins set to logic 1?
Or is it supposed to be output pin logic 1 and VCC? Or some combination?
