I2C on P1 Working

Below is a image of the Accelerometer and I2C lines. I never found any shorts, must be a bad joint under the P1.

If not thing is connected to the I2C line as a slave, should the SCL (clock) still run. I was unable to even get a clock reading on the SCL line.

AFAIK, the master will only toggle the clock when transmitting ( or expecting the slave to transmit ). So you won’t measure any clock unless you try to constantly transmit.

@peekay123, after much trouble shooting, I have it finally working after some surgery (single strand soldered to gnd)!

Even though I had my ground connections on the schematic, somehow the actual traces were not named correctly so it actually never had any ground connections.
