正文摘要:我用74HC595，串專并輸出到數碼管，但是不能正常輸出，麻煩大佬們幫我看下程序，也給我點用這個單片機檢測電壓并輸出到數碼管的建議，蟹蟹#include "reg51.h" #include "intrins.h" #define FOSC 18432000L ... |

采樣到的數據應該要進行冒泡法處理過后比較好吧 |
聽說中斷函數不能太長，我就把AD數據處理函數移動到了while里，如下：
 最后附上最新修改的全程序：

HC6800-ES-V2.0 發表于 2017-12-6 10:31 現在可以正常顯示了，但是無法及時更新AD檢測的值，要重新上電，并且先給595供電才能正常地顯示新的數值  |
wulin 發表于 2017-12-6 12:45 不是的啊，我在main函數里進行了ADC的初始化，在ADC初始化函數里是打開了AD轉換的
謝謝你認真看了我的代碼。我又檢查了下，是我昨天把數碼管的高低位連接亂了（尷尬……），但是，現在的問題是，AD轉換的數值不會及時更新，要斷電后重新上電才能檢測到新的待測電壓。由于手頭沒有74HC595的芯片，所以借用單片機上的，因此595和STC15W408AS單片機是分別供電的。這又出現了個問題，要先打開595的電源，再給單片機供電才能正常顯示………… |
| 你屏蔽了BYTE GetADCResult(BYTE ch)就不會發生ADC轉換中斷，所有程序都在中斷里運行，這怎么跑得起來？ |

程序太長，沒時間仔細看。只看清楚了你的ADC設置。 你的595沒有初始化，應該是問題所在吧。 主函數里，加一句：Hc595SendByte(0x00); 我有一個例子程序，是用ADC讀搖桿的，用串口發送數據。 #include <STC15F2K60S2.H> #include <intrins.h> unsigned int ADCdate; unsigned char ADC_XS[4]; void Delay500ms() //@11.0592MHz { unsigned char i, j, k;
