Other Parts Discussed in Thread: DLPC2607
I've had the basic I2C connection on my RPi3 working for months, and it correctly identifies my 20x4 LCD and a sensor when I run i2cdetect -y 1. But when I connect those same two i2c wires to the DLP EVM, no i2c addresses are identified by i2cdetect. I've tried disconnecting the two (working) i2c devices, leaving only the DLP, but same story, i2cdetect does not see the module. I know the RPi3 runs its i2c pullups to 3.3V; might the DLP EVM be expecting 5V i2c instead of the 3.3v the RPi3 sends? Anyone who has their DLP speaking i2c to their RPi3, would you please tell me exactly how you did that?
