I2Cx_Start
I2Cx_Restart
Prototype
void I2Cx_Start();
Description Determines if the I²C bus is free and issues START signal.
Parameters None.
Returns Nothing.
Requires MCU with at least one I²C module.
Used I²C module must be initialized before using this function. See I2Cx_Init routine.
Example
// Issue START signal
I2C1_Start();
Notes 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 3.
Number of I²C modules per MCU differs from chip to chip. Please, read the appropriate datasheet
before utilizing this library.
