HACK: Open source USB stack on MCP2200
Microchip has a new USB->serial converter chip called the MCP2200. We suspected they made this chip from a 20-pin PIC. The MCP2200 pinout is like other PIC uCs, and it has similar reset pin and internal voltage regulator circuits. We hooked up our trusty PICKIT3 and read the device ID. The MCP2200 was recognized as a […]
