I've been making progress on this ... but nothing solid to report yet. I'm debugging some code added for my version to act as a I2C Slave, so the uLCD-32PT module (the I2C Master) can query MPGuino values.

This requires a four-wire connection to an Arduino (5V power, ground, SCL, SDA) but I haven't yet figured out how these will be connected to the MPGuino.

Here's a plug for 4dsystems ... I managed to 'kill' the LCD screen by misadventure, and sent an email to their support forum. They told me about a surface-mount protection diode on the uLCD board and the part number ... ordered one from DigiKey and the board is working again. This also marks my first use of solder paste to solder the tiny (<1/8 inch) part onto the board, with the assistance of a magnifying glass of course!

In the future I shall not hook up wires with the board(s) under power!
