mikroC provides routines which implement software I²C. These routines are hard-
ware independent and can be used with any MCU. Software I2C enables you to
use MCU as Master in I2C communication. Multi-master mode is not supported.
Note: This library implements time-based activities, so interrupts need to be dis-
abled when using Soft I²C.

void Soft_I2C_Config(char *port, const char SDI, const char SD0,
const char SCK);
Description Configures software I²C. Parameter port specifies port of MCU on which SDA and SCL
pins are located. Parameters SCL and SDA need to be in range 0–7 and cannot point at
the same pin.
Soft_I2C_Config needs to be called before using other functions from Soft I2C
Library.
Example
Soft_I2C_Config(PORTB, 1, 2);
