Papilio One : Flashing an LED at a specific frequency

Shane Ormonde9 years ago9 years ago03 mins

To flash an LED at a specific frequency we need to divide the input clock frequency. In VHDL this can be done using counters. The Papilio One FPGA board comes with a 32MHz oscillator. 32Mhz means 32 million pulses per second, if you wanted to divide this down to 1Hz you could just set an…
