1.13 SPI Driver Synchronous - Multi Instance

This example writes and reads data to and from two separate EEPROMs connected over different SPI buses by using the multi instance feature of a synchronous SPI driver. The example also demonstrates how to setup two different instance transfers at different baud rates.

The example has three RTOS threads for the purpose:

• APP_EEPROM1_Tasks:
  • This thread performs write-read operation on the first EEPROM every 1 second
• APP_EEPROM2_Tasks:
  • This thread performs write-read operation on the second EEPROM every 1 second
• APP_MONITOR_Tasks:
  • This thread checks the status of transfers on both the EEPROMs and turns on the LED if the transfers are successful
  • It checks the status of the transfers every 100 milliseconds
