標(biāo)題: MSP430實(shí)現(xiàn)計(jì)時(shí)器的源代碼
和上一篇文章一樣，用到了 TM1638。計(jì)時(shí)器初值設(shè)為 23:57:45，計(jì)時(shí)到 23:59:59 時(shí)重置為 0點(diǎn) 0分 0秒。
（和上次的定時(shí)器一樣，主函數(shù)中的delay是我自己寫的，是為了便于調(diào)試，并沒有真正起到延時(shí)1s的作用）

源の代碼：

#include "TM1638.h"
#include "msp430f6638.h"
#include "stdint.h"

uint8_t num[8]; //各個(gè)數(shù)碼管顯示的值
uint8_t led_flag[8];

}

void TM1638_Write(unsigned char DATA) { //寫數(shù)據(jù)函數(shù)
unsigned char i;
DIO_OUT;
for(i=0;i<8;i++) {
   CLK_low;
   if(DATA & 0x01)
      DIO_high;

   CLK_high;

            temp |= 0x80;
      else
            temp &= 0x7f;
      CLK_high;
}
return temp;

TM1638_Write(DATA);
STB_high;

unsigned char times = 1;
while(times--) {
      Write_allLED(tab2[count]);
      count++;
      if(count == 16)
         count = 0;
      _delay_ms(100);
