I2C_master_init

Description

This function initialises the I/O pins to be used for the I2C bus and generates an I2C start / stop condition which puts any attached I2C peripherals into a known state (this is kind of like resetting the I2C bus).

The I/O pins used as the I2C bus are defined by the constants SCL, SDA, SCL_port and SDA_port.

SCL_port and SDA_port and defined as PORTA within the library i2c_bb_lib.bas

The bits within PORTA bust be defined by the user before i2c_bb_lib.bas is included with the user program

e.g.

const	SCL = 3
const	SDA = 4

include "i2c_bb_lib.bas"
