display.c

用iAR编写的AD转换程序

#include "includes.h"



void SendToDisplay(uchar s);

void Display(uint data, uchar channel)
{
    uint  temp;
    uchar i;
    uchar s[6];
    temp = data;
    for (i = 0; i < 5; i++) {
        s[i] = (temp % 10);
        temp /= 10;
    }
    s[5] = channel - 3;
    s[0] |= (s[1] << 4 );
    s[1]  = ((s[3] << 4)|s[2]);
    s[2]  = ((s[5] << 4)|s[4]);  
    PORTB &= ~(1 << channel);
    for (i = 0; i < 3; i++) {
        SendToDisplay(s[i]);
    }
    PORTB |= (1 << channel);
}
