updateEEPROM16()

[EEPROM]

void updateEEPROM16(unsigned short address, unsigned short value);

Description

Updates the EEPROM memory with the specified short value at the specified address.

Parameters

address: the address where the data will be written.

value: the data to be written if the data is different from the data already stored in the EEPROM memory.

Returns

Nothing.

Example Code

The code initializes the EEPROM with a size of 1024 and a width of 2 bytes and updates the value in the EEPROM memory at the address 0x00 with a counter value, incrementing it by one each time the loop is executed.

void setup() {
    beginEEPROM(1024, 2);          // initializes the EEPROM memory with a size of 1024 * 2 bytes
    writeEEPROM16(0x00, 0x0000);   // writes the value 0x0000 to the EEPROM memory at the address 0x00
}

void loop() {
    unsigned short value = readEEPROM16(0x00);  // reads the value from the EEPROM memory at the address 0x00
    value++;                                   // increments the value by one
    updateEEPROM16(0x00, value);               // updates the value in the EEPROM memory at the address 0x00
}

Notes and Warnings

• The updateEEPROM16() function can only be used after the beginEEPROM() function.
• The value parameter must be a 16-bit value (0-65535) or an unsigned short.
• If the programmer initializes the EEPROM with a width lower than 2 bytes, the function will write only 8 bits of the data.
