// Processor header file
// Delay routines header file
// Standard Library header file
// I2C routines header file
// Control byte definition for 24LC01B
C17 ’C’ code for using
// I2C address of 24LC01B
// Data written to 24LC01B
// Data read from 24LC01B
// Preset address to 0
// Configure I2C Module Master mode, Slew rate control on
// Configure clock for 100KHz
// Loop 128 times, 24LC01B is 128x8
// Write data to EEPROM
// Poll the 24LC01B for state
// Read data from EEPROM into SSPBUF
// Loop as long as data not correctly
//
// Increment address
// Done writing 128 bytes to 24LC01B, Loop forever
