Exemple #1

Fichier : eeprom.c Projet : LukeGary462/T-962-improvements

int32_t EEPROM_Read(uint8_t* dest, uint32_t startpos, uint32_t len) {
	int32_t retval=0;
	if(startpos<256 && dest && len && len<=256) {
		uint8_t offset=(uint8_t)startpos;
		retval = I2C_Xfer(EEADDR, &offset, 1, 0); // Set address pointer to startpos
		if(!retval) retval = I2C_Xfer(EEADDR | 1, dest, len, 1); // Read requested data
	}
	return retval;
}
