The EEPROM driver provides API to read and write to I2C based EEPROM devices present in the board. The driver takes care of all sequencing necessary to perform writes across pages and the application need not take care of the programming intricacies.

Features Supported

• Read and write API from any offset
• Provide API to return EEPROM attributes like size, page size etc

SysConfig Features

Note

It is strongly recommend to use SysConfig where it is available instead of using direct SW API calls. This will help simplify the SW application and also catch common mistakes early in the development cycle.

• Option to select EEPROM type based on board
• Supported EEPROMs

    - AT24C
  

• Option to set the I2C address of the EEPROM

Features NOT Supported

NA

Important Usage Guidelines

None

Example Usage

Include the below file to access the APIs

#include <board/eeprom.h>

EEPROM Read API

    status = EEPROM_read(handle, 0, buffer, 100);
    DebugP_assert(SystemP_SUCCESS == status);

EEPROM Write API

    status = EEPROM_write(handle, 0, buffer, 100);
    DebugP_assert(SystemP_SUCCESS == status);
