WebJul 11, 2024 · So, the EEPROM functions in your driver code probably need to first set the CS pin low, do some SPI operation, and set it high again after that. For convenience, I usually add some simple helper functions to the driver source file: Reading from the EEPROM basically follows the same three step process as writing to the EEPROM: 1. Send the Most Significant Byte of the memory address that you want to write to. 2. Send the Least Significant Byte of the memory address that you want to write to. 3. Ask for the data byte at that location.

WebNov 27, 2024 · EEPROM.c contains the function written by the user to handle the writing and reading operation with EEPROM: unsigned char Read_EEPROM(addr, device) reads from cell memory address (addr)and store the content in dato. void Write_EEPROM(addr, dato, device) writes data (dato) to memory address (addr). EEPROM (also called E PROM) stands for electrically erasable programmable read-only memory and is a type of non-volatile memory used in computers, usually integrated in microcontrollers such as smart cards and remote keyless systems, or as a separate chip device to store relatively small amounts of data by allowing individual bytes to be erased and reprogrammed.
