Interesting SPI Routing with iCE40 FPGAs

A few weeks ago I posted about how much fun I was having with the Fomu FPGA development board while travelling. This project from Tim ‘mithro’ Ansell and Sean ‘xobs’ Cross is not new, but remains a favorite of mine because of how portable it is — the entire board can fit in your USB port! The Fomu includes a Lattice Semiconductor iCE40 UltraPlus 5K, which has been a popular FPGA option over the past few years due to the reverse engineered bitstream format and ability to program it with a fully open source toolchain (see updated repository here).
