I2C on devboard

PostPosted: Tue Feb 03, 2009 6:41 am

I'm trying to use the I2C bus on the Pumpkin CubeSat kit devboard. I have some code that reads the temperature from a LM75 sensor, and that works great on TI's(minimal) MSP430 board (the board with just the bare CPU). However, it doesn't work on Pumpkin's devboard; for some reason the MSP430 never receives data on the I2C lines.

Does anyone have an idea of what could be the small difference between the two boards that perturbs the I2C bus ? (the SD card reader ?? FYI I'm not using it)

Thanks in advance for your help,
