Announcing a new project upload: a MMC (multimedia card) to serial adapter. This exposes the MMC card to a standard serial interface. It was originally designed for use with a Palm V, but any host capable of a 115kbps serial link could be used instead.

This is based around a 2313 and a MAX3223 RS232 chip, and utilises software SPI, UART and sleep. The whole thing runs of 2xAA batteries.

The project archive includes schematics, documentation and source code. There will be more information soon on my website, linked from http://homepage.ntlworld.com/sea..., and most likely a project on SourceForge for different host implementations of file systems.
