BÀI 9 : ĐẾM TỪ 0 ĐẾN 9 PIC16F887 XC8

Đây là ảnh mô phỏng protues.
đếm từ 0 đên 9 pic16f887 xc8
- Đây là code chương trình.
#include <xc.h>
#include <stdio.h>
#include <stdlib.h>
#define _XTAL_FREQ 8000000
// CONFIG1
#pragma config FOSC = HS        // Oscillator Selection bits (HS oscillator: High-speed crystal/resonator on RA6/OSC2/CLKOUT and RA7/OSC1/CLKIN)
#pragma config WDTE = OFF       // Watchdog Timer Enable bit (WDT disabled and can be enabled by SWDTEN bit of the WDTCON register)
#pragma config PWRTE = OFF      // Power-up Timer Enable bit (PWRT disabled)
#pragma config MCLRE = OFF      // RE3/MCLR pin function select bit (RE3/MCLR pin function is digital input, MCLR internally tied to VDD)
#pragma config CP = OFF         // Code Protection bit (Program memory code protection is disabled)
#pragma config CPD = OFF        // Data Code Protection bit (Data memory code protection is disabled)
#pragma config BOREN = ON       // Brown Out Reset Selection bits (BOR enabled)
#pragma config IESO = OFF       // Internal External Switchover bit (Internal/External Switchover mode is disabled)
#pragma config FCMEN = OFF      // Fail-Safe Clock Monitor Enabled bit (Fail-Safe Clock Monitor is disabled)
#pragma config LVP = OFF        // Low Voltage Programming Enable bit (RB3 pin has digital I/O, HV on MCLR must be used for programming)
// CONFIG2
#pragma config BOR4V = BOR40V   // Brown-out Reset Selection bit (Brown-out Reset set to 4.0V)
#pragma config WRT = OFF        // Flash Program Memory Self Write Enable bits (Write protection off)
const unsigned char Code7Seg[] = {0xC0, 0xF9, 0xA4, 0xB0, 0x99, 0x92, 0x82,0xF8, 0x80, 0x90};
unsigned int count=0;
void main (void)
{
    TRISC = 0X00;
    PORTC = 0XFF;
    while(1)
    {
        __delay_ms(100);
        PORTC = Code7Seg[count];
        __delay_ms(300);
        count++;
        if(count==10)
        {
            count = 0;
        }
    }
}
Code rất đơn giản và ngắn gọn ai chưa hiểu chỗ nào comment ở dưới mình sẽ trả lời nha. Các bạn thử tìm hiểu cách viết sử dụng vòng lặp for đi nha ! Cách này cũng rất hay.
