#169394 - A doubt about programming the P89v51RD2. |
I'm learning to program the NXP P89V51RD2 on a development board I designed. I'm using Keil to program the chip and Flash Magic to burn it. I started today by writing the following LED blinking program:
------------------------------------------------------ #include<reg51.h> #include<stdio.h> sbit LED=P1^0; //LED is connected to pin P1.0. void main() { LED=0; for(x=0;x<1275;x++) for(y=0;y<1000;y++); LED=1; for(x=0;x<1275;x++) for(y=0;y<1000;y++); } ------------------------------------------------------- What should be the ideal response to the above program? In the case of my board, the LED blinks continually.Shouldn't the LED just blink once and then die out? Since I'm programming in C for the first time, I really don't know what to do. Thank you! Yash. |
