SPI Driver asynchronous - multi instance

This example demonstrates how to use multiple instances of the SPI driver in asynchronous mode to communicate with multiple EEPROMs

Description

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

Downloading and building the application

Setting up the hardware

The following table shows the target hardware for the application projects.

• To run the demo, the following additional hardware are required:
  • Two EEPROM 4 Click boards

Setting up PIC32MK MCM Curiosity Pro Board

• Connect a micro USB cable to the USB DEBUG port J500
• Install two EEPROM 4 Click boards on to the two mikroBUS sockets (J300 and J301) of PIC32MK MCM Curiosity Pro Board

Running the Application

1. Build and program the application using its IDE
2. The LED is turned ON when the data read from the EEPROMs matches with the data written to the EEPROMs

Refer to the following table for LED name:
