Basic example showing how to use a M24LR64 EEPROM with the STM32746G_DISCOVERY board. This EEPROM can be found on the additional ANT7-M24LR-A daughter board.
Dependencies: BSP_DISCO_F746NG
This example shows how to read and write data in RF EEPROM. The I2C EEPROM memory (M24LR64) is available on separate daughter board ANT7-M24LR-A, which is not provided with the STM32746G-Discovery board. To use this driver you have to connect the ANT7-M24LR-A to CN1 connector of STM32746G-Discovery board.
