1.16 SERCOM I2C EEPROM Read Write
This example application demonstrates how to use the SERCOM peripheral to write and read from the I2C serial EEPROM memory.
Description
This example uses the I2C peripheral library to write an array of values to the I2C Serial EEPROM and verify the value written by reading the values back and comparing it to the value written.

Setting Up PIC32WM-BW1 Curiosity Board
- Plug the EEPROM 3 Click Board™ into the mikroBUS socket of the PIC32WM-BW1 Curiosity board
- Connect the USB port on the board to the computer using a USB Type-C cable
Running the Application
- Build and program the application using its IDE.
- LED indicates success or failure:
- The LED is turned ON when the value read from the EEPROM matched with the written value
- The LED is turned OFF when the value read from the EEPROM did not match with the written value
Refer to the following table for LED name:
| Board | LED Name |
|---|---|
| PIC32WM-BW1 Curiosity board | Green LED |
