1.18 SERCOM SPI EEPROM Read Write
This example application demonstrates how to use the SERCOM SPI peripheral to write and read from the SPI serial EEPROM memory.
Description
This example uses the SERCOM SPI peripheral library to write an array of values to the SPI Serial EEPROM and verify the value written by reading the values back and comparing it to the value written.

| wbz451_curiosity.X | PIC32CX-BZ2 and WBZ451 Curiosity Board |
Setting Up PIC32CX WBZ451 Curiosity Board
- Plug an EEPROM 4 Click board into the mikroBUS socket of the mikroBUS Xplained Pro board
- Connect the Debug USB port on the board to the computer using J16a micro USB cable
Running the Application
- Build and Program the application project using its IDE
- LED indicates the success or failure:
- LED is turned ON when the value read from the EEPROM matched with the written value
- LED is turned OFF when the value read from the EEPROM did not match with
the written value
