Reusing the Upduino Programmer for USB→FPGA Communication
The Upduino FPGA development board is a cheap way to start with (OSS) FPGA development on the Lattice ICE40 platform. Unfortunately, there are few peripherals on the PCB and there’s no official way for communicate between FPGA application and PC. This post explains how we can reuse the FPGA programmer to transmit data to the FPGA without any additional hardware, using only the programmer USB port. ...
