ABL electronic PIC12 Benutzerhandbuch

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.

Soft_I2C_Config(char *port, const char SDI, const char SD0,

SCK);

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.

Soft_I2C_Config(PORTB, 1, 2);
