InvIoT - InvIoT_EEPROM.read8

.read8

DESCRIPTION

.read8 retreives a byte from an address in EEPROM

SYNTAX

.read8(int)

PARAMETERS

int, the address of EEPROM to retrive a byte

RETURNS

a byte

EXAMPLE

#include <InvIoT_EEPROM.h>
#include <Wire.h>

// Must run first the first Example to Write the Strings to EEPROM
