| + | ===== 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 ===== | ||
| + | <code cpp> | ||
| + | #include <EEPROM.h> | ||
| + | |||
| + | void setup() | ||
| + | { | ||
| + | for (int i = 0; i < 512; i++) | ||
| + | EEPROM.write(i, i); | ||
| + | } | ||
| + | |||
