i am working on pic16f877a. i wrote a simple program to drive the LED to
blink.
the simulation using gpsim say it work fine. Few LED should be blinking.
But, if i burn the
program to the PIC. nothing happen.
The circuit working ok. i did burn one hex files from another project
written in assembly and
program under MPLAB IDE (using M$ windows) - the LED blinking. But i want to
work in
Linux. Anyone come across the same problem. Anyone know the solutions?
#define __16f877a
#include "pic/pic16f877a.h"
/* Setup chip configuration */
typedef unsigned int config;
config at 0x2007 __CONFIG = _CP_OFF &
_WDT_OFF &
_BODEN_OFF &
_PWRTE_OFF &
_LVP_OFF &
_XT_OSC;
//delay
void delay(unsigned char a)
{
unsigned char i, j, k;
for(i = 0; i<a; i++)
for(j = 0; j < 10; j++)
for(k = 0; k < 255; k++);
}
//main
void main(void) {
while(1) { /* Loop forever */
//LED1-LED7
TRISD = 0x00;
PORTD = 0x3F; delay(1000);
PORTD = 0x00; delay(1000);
PORTD = 0x3F;
}
}
