10+ Mbit UART part II

Previously I wrote about about my need for high-speed RS-485 interface. I finally had both parts and time to try to set up and test it. I assembled the whole thing on a breadboard to simulate the noisy environment (definitely not because I didn't want to draw a board which might not work).

Custom STM32 board and USB re-enumeration issue

Lately I've been extensively using STMs USB Virtual Communications Port (VCP) - a serial port implementation over USB. It works reasonably well with the Discovery board I used for prototyping. But not so much with my custom board.
