I2Cx_Read

unsigned char I2Cx_Read(unsigned ack);

Description Reads a byte from the I²C bus.
Parameters - 

ack

: acknowledge signal parameter. If the 

ack = 0

, acknowledge signal will be sent after reading, 

otherwise the not acknowledge signal will be sent. 

Received data.

MCU with at least one I²C module.

Used I²C module must be initialized before using this function. See I2Cx_Init routine.

Also, START signal needs to be issued in order to use this function. See I2Cx_Start.

unsigned char take;

...

take = I2C1_Read(1);

- I²C library routines require you to specify the module you want to use. To select the desired I²C 

module, simply change the letter 

x in the routine prototype for a number from 1 to 5.

- Number of I²C modules per MCU differs from chip to chip. Please, read the appropriate datasheet 

before utilizing this library.

I2Cx_Write

unsigned I2Cx_Write(unsigned char data_);

Description Sends data byte via the I²C bus.
Parameters - 

data_

: data to be sent 

- 

0

 if there were no errors. 

- 

1

 if write collision was detected on the I²C bus. 

MCU with at least one I²C module.

Used I²C module must be initialized before using this function. See I2Cx_Init routine.

Also, START signal needs to be issued in order to use this function. See I2Cx_Start.

unsigned char data_;

unsigned error;

...

error = I2C1_Write(data_);

error = I2C1_Write(0xA3);
