[SOLVED] [Moved] Config bits in HI-TECH C Compiler for PIC10/12/16 MCUs (Lite Mode) V9.83

[bimalkamal]

A request to the members.
Anyone please give an answer to show how I can change the config bits in HI-TECH C Compiler for PIC10/12/16 MCUs (Lite Mode) V9.83

The following two lines giving errors (But was ok in older version)

#include <htc.h>
__CONFIG(MCLRDIS & UNPROTECT & BORDIS & WDTDIS & PWRTEN & INTIO);


After building I get :-------

Error [800] ser2.as; 45. undefined symbol "INTIO"
Error [800] ser2.as; 45. undefined symbol "PWRTEN"
Error [800] ser2.as; 45. undefined symbol "WDTDIS"
Error [800] ser2.as; 45. undefined symbol "BORDIS"
Error [800] ser2.as; 45. undefined symbol "UNPROTECT"
Error [800] ser2.as; 45. undefined symbol "MCLRDIS"

********** Build failed! **********

Re: Config bits in HI-TECH C Compiler for PIC10/12/16 MCUs (Lite Mode) V9.83

The issue you are experiencing is due to the use of the incorrect #defines or symbols for the __CONFIG() statement.

I usually add the appropriate device specific header file to the project and reference it for the correct #defines to use while coding.

The device specific header files can be found in the following path, modify to your particular installation:

C:\Program Files\HI-TECH Software\PICC\9.83\include

For instance if you were coding for a PIC16F877A, then you would add the pic16f877a.h header file to the project window.

Open it within MPLAB to find the correct #defines:

#warning Header file pic16f877a.h included directly. Use #include <htc.h> instead.
#endif

/* header file for the MICROCHIP PIC microcontroller
 *  16F877A
 */


#ifndef __PIC16F877A_H
#define __PIC16F877A_H

// Code protection off
#define CP_OFF               0xFFFF
// All program memory code-protected
#define CP_ON                0xDFFF

Using the above #defines the correct __CONFIG() statement would be:

__CONFIG(CP_OFF  & BOREN_OFF & WDTE_OFF & PWRTE_ON & FOSC_HS );

You can not disable the MCLR on a PIC16F877A nor does it have an internal oscillator, therefore the disable MCLR #define was omitted and the oscillator set to High Speed Oscillator (FOSC_HS).

Once again BigDogGuru magic worked!!!!!!!!!!

Now its compiling without any error.

how to set config bits in 16f887 as it have MCLR enable/disable capability and also internal osc,

I am getting problem to use internal osc, and also gives problem with original LCD.C problem, it gives busy statement while simulate on Proteus, so i change __delay_us(E_Delay) to __delay_us(10); and it works well, but i think i am unable to set the bits for internal osc, can u plz help for complete config file that i can work with?

I am using MPLAB 8.85 with HiTech C 9.83
#include "Includes.h"
#include <pic16f887.h>
// Configuration word for PIC16F877
__CONFIG( FOSC_INTRC_NOCLKOUT & MCLRE_OFF & BOREN_ON & WDTE_OFF & PWRTE_ON & CP_OFF 
		& LVP_OFF & CPD_OFF   & IESO_OFF & CPD_OFF & FCMEN_OFF & BOR4V_BOR40V);
