This is an active serial loopback project using PicoBlaze and Verilog. It's purpose is to demonstrate the use of UART code (attribution: Jim Patchell) in conjunction with a PicoBlaze. The PicoBlaze program waits for a byte to come in on the receiver and then transmits the byte. This forms an active loopback. The design also lights the LEDs with the current data byte.
