Good Day, i am a novice programmer and am trying to compiler a code for micro controller AT89C52 using a reference code but i keep running to an error which seems to be causing other errors.
#include <reg52.h> //header file sbit TSTART_1 = P1^2; sbit TSTART_2 = P1^3; sbit INP_1 = P1^0; sbit INP_2 = P1^1; sbit door_en = P2^5; sbit door_in1 = P2^4; sbit door_in2 = P2^1; sbit door_sw1 = P2^2; sbit door_sw2 = P2^3; sbit in1 = P3^1; sbit in2 = P3^2; sbit en1 = P3^0; sbit en2 = P3^3; sbit in3 = P3^4; sbit in4 = P3^5; sbit BUZZER = P3^6; sbit digit1 = P2^7; sbit digit2 = P2^6; sbit red_led = P1^4; sbit green_led = P1^5; sbit seg_A = P0^0; sbit seg_B = P0^1; sbit seg_C = P0^2; sbit seg_D = P0^3; sbit seg_E = P0^4; sbit seg_F = P0^5; sbit seg_G = P0^6; bit time_count_flag = 0x01; void delay1(); void delay_3sec(); void delay_buzzer(); void timer0_init(); void timer1_init(); void display_led(unsigned char); int time_count=0, count, count1=0;
I could post the full code due to character limits, here is the continuation
void main() { P1=0XFF; BUZZER=0; P0=0X00; timer0_init(); while(1) { while(1) { if(TSTART_1==0) { red_led=1; green_led=0; en1=0; en2=0; BUZZER=1; delay_buzzer(); BUZZER=0; delay1(); door_en=1; door_in1=1; door_in2=0; delay1(); door_en =0; timer1_init(); while(1) { if(INP_1==1) { while(INP_2 ==1); count = count+1; if(count >=25) { BUZZER=1; delay_buzzer(); BUZZER=0; delay_3sec(); door_en=1; door_in1=0; door_in2=1; delay1(); door_en=0; } delay1(); } if(INP_2 ==1) { while(INP_1==1); count = count-1; if(count <= 0) { count = 0; } delay1(); } if(time_count_flag ==1) { TR1=0; time_count_flag = 0; TH1=0X00; TL1=0X00; ET1=1; TR1=1; BUZZER=1; delay_buzzer(); BUZZER=0; delay_3sec(); door_en=1; door_in1=0; door_in2=1; while(door_sw2==1); door_en=0; } }//end while
Continuation
BUZZER=1; delay_buzzer(); BUZZER=0; delay_3sec(); door_en=1; door_in1=0; door_in2=1; while(door_sw2==1); door_en=0; green_led=1; red_led=0; en1=1; in1=1; in2=0; en2=1; in3=1; in4=0; while(TSTART_2==1); while(TSTART_2==0); break; }//end if }//end while } //end while
Ignore this post, found the problem.... can the mods delete this post
