Table 76. I2Cs_ITFunction
Note: You must use this function only inside the Interrupt service routine.
Caution: Special care must be taken when you write code with this function inside the interrupt
EXAMPLE:
The following C program shows the uses of the I2C functions.
Program Description:
This program runs the following sequence for the I2C slave (ST72F63B 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,
You can select any one pair of the following communication modes.
For Polling Mode,
For Interrupt Driven Mode,
/* You can use a time out 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.*/
