mikroC provides library which implements software UART. These routines are
hardware independent and can be used with any MCU. You can easily communi-
cate with other devices via RS232 protocol – simply use the functions listed
below.

Note: This library implements time-based activities, so interrupts need to be dis-
abled when using Soft UART.

Soft_Uart_Init(unsigned short *port, unsigned short rx,

tx, unsigned short baud_rate, char inverted);

Initalizes software UART. Parameter 

port

specifies port of MCU on which RX and TX

pins are located; parameters 

rx

and 

tx

need to be in range 0–7 and cannot point at the

same pin; 

baud_rate

is the desired baud rate. Maximum baud rate depends on PIC’s

clock and working conditions. Parameter 

inverted

, if set to non-zero value, indicates

inverted logic on output.

Soft_Uart_Init

needs to be called before using other functions from Soft UART

Library.

Soft_Uart_Init(&PORTB, 1, 2, 9600, 0);
