Lattice iCE40 Ultra Plus FPGA: Gnarly Grey Upduino – Tutorial 1: The basics

A how-to getting an LED flashing using VHDL from Harris’ Electronics:

The cheap price however comes with a few niggles, namely getting it up and running in the first place with the limited documentation. Gnarly Grey do a great job of explaining programming a starting program but don’t say much about further development. With that in mind, I’m going to run through the methodology of getting an LED flashing using VHDL. There seem to be a fair few Verilog methods but not many people seem to have touched upon VHDL with these FPGAs.
