I2Cx_Init_Advanced

void I2Cx_Init_Advanced(unsigned long Fclk_Khz, unsigned long scl);

Description This function configures and initializes the desired I²C module using Peripheral Bus Clock and default 

initialization settings.

As per the I²C standard, SCL clock may be 100 kHz or 400 kHz. However, the user can specify any 

clock rate up to 1 MHz.

Parameters - 

Fclk_Khz

: Peripheral Bus Clock frequency in kHz. 

- 

scl

: requested serial clock rate. 

Nothing.

MCU with the I²C module.

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

- 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_Start

void I2Cx_Start();

Description Determines if the I²C bus is free and issues START signal.
Parameters None.
Returns

Nothing.

MCU with at least one I²C module.

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

I2C1_Start();

- 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
