EEPROM

write()

Description

Write a byte to the EEPROM.

Syntax

EEPROM.write(address, value)

Parameters

address: the location to write to, starting from 0 (int)

value: the value to write, from 0 to 255 (byte)

Returns

none

Note

An EEPROM write takes 3.3 ms to complete. The EEPROM memory has a specified life of 100,000 write/erase cycles, so you may need to be careful about how often you write to it.

Example

#include <EEPROM.h>

void setup()
{
  for (int i = 0; i < 512; i++)
    EEPROM.write(i, i);
}

void loop()
{
}
