Witam. Posiadam program do Arduino Uno, który służy do zapisywania zawartości 4 eepromów i2c o adresach 80, 81, 82, 83. Przed zapisem muszę sprawdzić innym programem do skanowania adresów i2c jaki adres ma dany eeprom i zmodyfikować program wpisując odczytany adres w skanerze w pozycję: #define EEPROM_I2C_ADDRESS 83, gdzie 83 to np. adres jednego z chipów. Proszę o podpowiedź, w jaki sposób zmodyfikować program, aby na początku odczytał adres, wybrał odpowiedni wsad dla danego adresu i zapisał w eepromie. Załączam kod programu do zapisu:

Kod:

#define EEPROM_I2C_ADDRESS 83
#include <Wire.h>

// blank data for K, C, M & Y chip. 128 array of data.
