Overview
The LPI2C Example project is a demonstration program that uses the KSDK software to manipulate the Low Power Inter- Integrated Circuit. The example uses two instances of LPI2C, one in configured as master and the other one as slave. The LPI2C master sends data to LPI2C slave. The slave will check the data it receives and shows the log.
