Debugging with the FTxxxx Mini-Modules

[zygot]

I often use a UART for debug and as a user interface for projects. 921600 baud that can be used with any serial terminal program is nice for some things but sometimes you need a faster, more flexible interface. Here I provide an FPGA interface that uses 4 pins and a separate FT4332H or similar mini-module to access design resources 1.2 MiB/s full duplex. The first demo is for the CMOD-A735T.

The demo has something of interest for most readers besides a faster UART.
