I2C on TM4c1294 doesn't work

Recommended Posts

Hi Rei Vilo,

the issue is with the Launchpad itself and not with DS1307 or any other device on a Bus. The I2c communication is somehow faulty on Launchpad, due to the fact that the same setup on Arduino Mega runs perfectly fine. When running the i2c scanner on launchpad it show dozens of devices on Bus, instead of just 4.
