Just checking in to see if anyone has tested the I2C on the P1 yet? I have a MMA7660 accelerometer connected and the code worked with the photon and core. But I am not getting any response from the accl. when connected to the P1.
I have 2.2K pull-up on the lines.
@peekay123, do you know of anyway to test or confirm I2C is working? Last night I was using a scope but all i got was the pull-up voltage. I confimed I had the right settings by connecting a proto MMA7660 board to a photon and was able to measure the 100K clock freq. on that setup.
