Writes ASCII characters to the MMC, reads them back and sends the characters
to the linux machine via the serial port. Use "serterm" for testing:
PIC - MMC (Multi Media Card) Flash Memory Extension
It is easy to interface a MMC (MultiMediaCard) with a MicroChip PIC via the SPI (Serial Port Interface). This is a very handy data logging circuit with lots of memory for data storage. I2C RAM's or EEPROM's are hardly available at sizes bigger than 256kb, but this solution with a 64MB Flash MMC is not to beat in both cost effectiveness and storage volume!
