STM32 I2C EEPROM with HAL
#Talking to a I2C EEPROM using the STM32 HAL libraries This mostly a note to my future self. This code is based on the excellent answers provided at the ST forums, but combined here as a complete class. This was used to talk to a standard I2C EEPROM, 24LC256. The following header file definitions are required for the class : #define EEPROM_ADDRESS 0xA0 #define EEPROM_MAXPKT 32 //(page size) #define EEPROM_WRITE 10 //time to wait in ms #define EEPROM_TIMEOUT 5*EEPROM_WRITE //timeout while writing #define EEPROM_SECTIONSIZE 64 These setup the I2C address, the maximum page size of the EEPROM (32 used here for compadability)....
