[Sdcc-user] Why doesn't this work?

[Dominik C. <do...@ca...>]

I have this code with a nested for loop and when I flash the micro it
just hangs. On port 2 there are 8 leds, so it should be like a binary
counter. If I only have the outer loop it works, but it is too fast, so
I only see the MSB blinking. When I load the program with the debugger
it crashes.


Thanks for the answers.


#include "LPC935_936.h"


void sys_init( void ) {
	P2M1 = 0x00;
	P2M2 = 0x00;
}

void main(void) {
	char i,j;
	char temp = 0;

	sys_init();	
	while(1) {
		for(i = 255; i > 0; i--) {
		       for(j = 5; j > 0; j--);
		}
		temp++;
		P2 = temp;
	}
}
