Re: Hello i want to start pic programming with Hitech c can any one help me

Thanks,
PA3040, nikhilsigma, ec_nisarg.

dear 'nikhilsigma' ,
one question to u plz clear me
1. #define status PORTDbits.RD1

here,
Does 'status' mean STATUS register which contains C,Z,RP0,RP1 etc. bits or PORTD1 is definning as 'status' symbol???

if 'status' is not STATUS, then can i write
#define status PORTD,RD1

at the end to "PA3040, nikhilsigma, ec_nisarg" and to all plz send me more easy samples to understand and help to program

#define creates aliases. With #define status PORTDbits.RD1 statement you can use status = 1 or status = 0 like that in your code instead of PORTDbits.RD1 = 1 or 0
Another example if you have an LED on PORTBbits.RB0 then you can use #define LED PORTBbits.RB0 and in code refer to it like LED = 1, LED = 0, LED = ~LED.

with this code further u can develop yourself

/*****		uC Series : PIC16F877A						*****/
/*****		Prog Lang : Hi-tech C						*****/

#include <pic.h> 

unsigned long delay;

void mc_init();

 void main()
 {
	mc_init();

	delay=500;
	while(delay--);

	do
	{
		RC0=1;  // pointing single pin to toggle
		PORTB=0XFF;  // entire port toggling
		delay=50000;
		while(delay--);

		RC0=0;
		PORTB=0X00;
		delay=50000;
		while(delay--);

	
					
	}while(1);
}

void mc_init()
{
	// configure as per ur requirement : 1- I/P ,   0-O/P
	TRISA=0x0F;   
	TRISB=0xFF;
	TRISC=0xFE;   // 11111110 - RC0 only O/P
	TRISD=0x00;
	TRISE=0x00;

	// Reset all port after initialize 	
	PORTA=0X00;
	PORTB=0X00;
	PORTD=0X00;
	PORTC=0X00;
	PORTE=0x00;
	}

#define status PORTD,RD1

this is wrong, you should write

#define status PORTDbits.RD1

"PORTxbits" is a structure in include file of pic.
they have made such structures for all sfrs, you can access individual bits by accessing members of such structures,
if you are using mplabx, when you just type ****bits. it will show you available members.

- - - Updated - - -

don't merge status with STATUS.

try different name as alias than SFR names, to avoid misleads.
