Armed with a PIC18F ‘micro, realized that programming in C would be too slow, he needed to go all the way down to the bare metal and program his micro in assembly. One of the difficulties of reading an N64 controller is simply the speeds involved with only three pins on the controller port, the N64 controller uses a serial protocol to send 32 bits of controller data at a fairly fast rate. decided to throw his hat in the ring and give a try, and we’re pleased to report he’s been completely successful. We’ve seen NES, SNES, Sega, and just about every weird controller Atari put out connected to microcontrollers, but connecting the N64 controller to a project has remained one of those seldom-seen, rarely copied endeavors, not often tackled by makers around the globe.
