3.4 mikroC Pro for PIC Built-in Functions

mikroC Pro for PIC compiler includes a set of built-in library functions that can be used in programs. A list of these functions are given in Table 3.8. There is no need to use header files, except for the functions Lo, Hi, Higher and Highest, where the header file build_in.h should be included in the program. Built-in functions are implemented as inline, that is the function code is generated at the point of declaration in the program and the function is not called. The only exceptions to this rule are functions Vdelay_ms, Delay_Cyc and Get_Fosc_kHz.

Table 3.8 mikroC Pro for PIC built-in functions.

Function	Description
Lo	Returns the lowest byte of a number (bits 0 to 7)
Hi	Returns next to the lowest byte of a number (bits 8 to 15)
Higher	Returns next to the highest byte of a number (bits 16 to 23)
Highest	Returns the highest byte of a number (bits 24 to 31)
Delay_us	Creates software delay in microsecond units
Delay_ms	Creates constant software delay in millisecond units
Vdelay_ms	Creates delay in milliseconds using program variables
Delay_Cyc	Creates delay based on microcontroller clock
Clock_Khz	Returns microcontroller clock in KHz
Clock_Mhz	Returns microcontroller clock in MHz

Functions Lo, Hi, Higher and Highest are used to extract bytes from integers and long integers, as shown in the following example:

Functions Delay_us and Delay_ms can be used to generate microseconds and seconds delays in programs. ...
