EXAMPLE:
The following C program shows the uses of the I2C functions.
Program Description:
This program runs the following sequence for multimaster I2C (ST72F521 device) for I2C
Polling and I2C Interrupt driven communication modes:
1. Transmits a single byte passed by the user and receives single byte of data in 7 bit ad-
dressing mode,
2. Transmits and receives the10 bytes of data in 7 bit addressing mode.
The following modes are used for transmission and reception,
7 bit Tx - 7 bit master transmitter,
7 bit Rx - 7 bit master receiver,
You can select one pair of the following communication modes, for transmission
and reception respectively:
I2C_POLLING_TX
I2C_POLLING_RX
I2C_ITDRV_WITHOUTBUF_TX
I2C_ITDRV_WITHOUTBUF_RX
/* You can use a timeout function to handle the fault in which the control will get
stuck inside a loop.This function should have the Boolean return, i.e it should return
TRUE if the expected wait Time is not elapsed and FALSE if it is elapsed.*/
