The problem with FPGAs is that they’re so low-level. It’s a bit like sitting on the floor with a huge pile of 7400 series chips, trying to make them do something … u s e f u l ?
When starting from scratch (just for my own education and entertainment), one of the first things I’ll want is to hook up the FPGA to some nearby computer or µC.
The one tool that comes to mind is a serial UART interface, so let’s try and build one.
