Switches and leds on Spartan 3E.
One of the first things one has to learn when programming FPGA's is how to make use of the peripherals to see what is happening inside the board. Here I'll show how to make use of the switches and leds on the Spartan 3E FPGA board.
Making a counter.
In this case I show you how to build a counter using the leds, the FPGA clock and the push buttons on the Spartan 3E.
