USB to I2C/UART bridge question
Has anybody here had any experience with the MCP2221A from Microchip ?
It's a USB-> I2C/UART converter (basically preprogrammed PIC16F1455, most likely). It's not that great when it comes to baud rates (max is 460800 baud), and not that cheap either (~$2 in sigle quality) but it has nice package options (DIP included for breadboard users) and has four programmable GPIOs and ADC/DAC capabilities.
Could be useful as a P1 companion chip. Maybe.
