I read the 24lc32 memory using an Arduino UNO, an EEPROM module, and a level shifter. You can find these on Aliexpress for aprox 10 - 15 EURO.
1. I read the memory in HEX,
2. search data in locations 161, 162, 163, 164 -> 65 62 65 62
3. eliminate first character of each data - > 5252
4. 5252 XOR 5555 -> code 0707
The most difficult part was soldering wires to 24lc32 chip:
GND TO PIN 4
SDA TO PIN 5
SCL TO PIN 6
+3.3 V TO PIN 8
Arduino UNO is a 5 V board so I don't want to risk, I use a level shifter from SDA, SCL pins of memory chip to SDA, SCL pins of Arduino.
Thank you again.
hi. you can describe it in more detail. why do I need to do XOR 5555?
