1.27 SPI Driver Synchronous - Multi Client

This example demonstrates how to use single instance of the SPI driver in synchronous mode to communicate with multiple EEPROMs.

Description

This example write and read data to and from two separate EEPROM connected over the same SPI bus by using the multi client feature of the driver. The example also demonstrates how to setup two different EEPROM transfers at different baud rates.
