Hi all,

I am using TM4C123GH6PM development. I have configured one board as master and other board as a slave. I am trying to send data from master to slave. For Tiva C series, how to find slave address and register address to write data into the slave.

Best Regards,

Siva

The slave address is set by the application software running on the device being used as an I2C slave with a call to the TivaWare function "I2CSlaveAddressSet()". This is the address that the master will use when it calls the function I2CMasterSlaveAddrSet().

Sorry, I was busy and it took some time before I could get around to writing this example. I used an EK-TM4C123GXL launchpad and externally connected I2C0 to I2C2 and added external pull-up resistors. Import the project from the attached .zip file.
