Contents
1. Open the C/C++ editing perspective
2. Open the egpc project
3. Build, upload and run
What it does
This is an example test interface for reading/writing to the Linux I2C device interface. It is only relevant if the I2C device interface is enabled and an external I2C device is connected to the bus. See comments in i2c_test.c for details.
