I added a Verilog receiver module to my FPGA based RC switch. With this module it is possible to receive RC switch commands from a remote, or from an other FPGA running the the Verilog for sending RC commands. For demonstration I made a simple example which uses one of the build in LEDs of the FPGA for each of the channels (A, B, C, D) on the remote. Thus it is possible to turn the four LEDs on/off with the original remote. As an receiver a cheap module like this will do the trick. For the FPGA, I used again the Lattice MachXO2.
The updated code and more information could be found on github.
