1.12 SPI Driver Asynchronous - Multi Client
This example demonstrates how to use the single instance of the SPI driver in Asynchronous mode to communicate with multiple EEPROMs.
Description
This example writes and reads data to and from two separate EEPROMs 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.

- Connect mikroBUS Xplained Pro boards onto the EXT1 (J501) and EXT2 (J502) headers of the PIC32MK MCJ Curiosity Pro Development Board
Setting Up PIC32MK MCA Curiosity Pro Development Board
- To run the demo, the following additional hardware is required:
- Connect micro USB cable to the Debug USB connector (J1) on the board to the computer
- Install one EEPROM 4 Click board onto the mikroBUS socket of PIC32MK MCA Curiosity Pro Development Board
- Install another EEPROM 4 Click board onto the mikroBUS Xplained Pro board
- Connect mikroBUS Xplained Pro board onto the EXT1 (J501) header of the PIC32MK MCA Curiosity Pro Development Board
Running the Application
- Build and program the application using its IDE.
- The LED turns ON when the data read from the EEPROMs matches with the data written to the EEPROMs.
