The I2C compatible Two-Wire Interface Master mode (TWIM) demo. This demo uses the TWIM peripheral to read and write 8 bytes of data to arbitrary addresses on a device that are connected to the I2C pins p0_30 and p0_31. It demonstrates error handling if the device does not respond properly (or it is not connected).
