Hello developers
In my example, can't I write a new value to the EEPROM?
I did not find an example for recording anywhere in the description.
How to write a new value to the EEPROM correctly?
// 0x34 LPCD_REFERENCE_VALUE RW 1
//#define LPCD_REFERENCE_VALUE (0x34)
Serial.println(F("----------------------------------"));
Serial.println(F("Reading LPCD_REFERENCE_VALUE ..."));
uint8_t LPCD_REFERENCE_VALUE_v[1];
nfc.readEEprom(LPCD_REFERENCE_VALUE,
LPCD_REFERENCE_VALUE_v,
sizeof(LPCD_REFERENCE_VALUE_v)
);
Serial.print(F("LPCD_REFERENCE_VALUE= "));
Serial.print(LPCD_REFERENCE_VALUE_v[0], HEX);
Serial.println(" ");
// OLD Value LPCD_REFERENCE_VALUE= 8 dec 8
// New value LPCD_REFERENCE_VALUE= AC dec 172
uint8_t LPCD_REFERENCE_VALUE_vv[1];
LPCD_REFERENCE_VALUE_vv[0] = 172;
nfc.writeEEPROM(LPCD_REFERENCE_VALUE,
LPCD_REFERENCE_VALUE_vv,
sizeof(LPCD_REFERENCE_VALUE_vv)
);
Serial.println(F("------------ CHECK NEW VALUE ---------------"));
Serial.println(F("Reading LPCD_REFERENCE_VALUE ..."));
nfc.readEEprom(LPCD_REFERENCE_VALUE,
LPCD_REFERENCE_VALUE_v,
sizeof(LPCD_REFERENCE_VALUE_v)
);
Serial.print(F("LPCD_REFERENCE_VALUE= "));
Serial.print(LPCD_REFERENCE_VALUE_v[0], HEX);
Serial.println(" ");
exit(- 1);
Alexey.
