不完全檢測按下的按鈕

Question

我寫了一個短的函數，它檢測矩陣鍵盤上按下的按鈕，並寫下他的ID（48個按鈕，所以ID是0 - 47）。

問題是，它只檢測ButtonID 0，其他檢測非常難看，就像ButtonID 1爲ButtonID 3放置位置;

我在代碼中找不到任何問題...我初始化了所有權利（我希望），我正在檢測他們...但他們仍然有錯誤的ID。感謝您的任何迴應或解決方案。

其實我在代碼 爲ButtonID10測試還有就是我的代碼，我爲我的6（COLS）書面X8（行）矩陣鍵盤：

#include <avr/io.h> 

// PIN's Init definitions 
#define O(DIR,PIN) DIR |= (1 << PIN) // Marks PIN as output pin 
#define OX(DIR) DIR = 0xFF // Makes all PINs as output pins 
#define I(DIR,PIN) DIR &= ~(1 << PIN) // Makes PIN as input pin 
#define IX(DIR) DIR = 0x00 // Makes all PINs as input pins 
// PIN's SET definitions 
#define H(PORT,PIN) PORT |= (1<<PIN) // Makes PIN 5V 
#define HX(PORT) PORT = 0xFF // Makes all PINs 5V 
#define L(PORT,PIN) PORT &= ~(1<<PIN) // Makes PIN 0V 
#define LX(PORT) PORT = 0x00 // Makes all PINs 0V 
#define S(PORT,BIN) PORT = BIN // Makes PINs activated from binary pattern 
// PIN's GET definitions 
#define GET(GPIN,PIN) GPIN & (1<<PIN) // Reads digital value on PIN 
#define GET2(GPIN,BIN) GPIN & BIN // Reads digital value of binary defined PIN

int checkKeys(); 
void initPins(); 

int main(void) 
{ 
    initPins(); 

    //TESTS 
    OX(DDRH); 
    L(PORTH,PH1); 
    //TESTS 

    while (1){ 
     if (checkKeys() == 10){ 
      H(PORTH,PH1); 
     }else{ 
      L(PORTH,PH1); 
     } 
    } 

    return 0; 
} 

void initPins(){ 
    OX(DDRK); 
    IX(DDRF); 
} 



int checkKeys(){ 
    for (int x = 0; x < rows; x++){ 
     S(PORTK,binary[x]); 
     for (int y = 0; y < cols; y++){ 
      if (GET2(PINF,binary[y])){ 
       return (x*cols + y); 
      } 
     } 
    } 
    return -1; 
} 

Answer 1

好吧，我終於想通爲什麼我以前不工作。代碼是正確的，但我在int類型數組'binary'中犯了一個錯誤 - 第一個錯誤是他們是八進制數，第二個是我正在計數，沒有改變數值。

但是現在還有另一個問題...程序沒​​有檢測到最後2個（0,1,2,3是可檢測的而4,5個不是）。

相信我 - 我試圖解決這個問題，我甚至解決了整個單片機和所有按鈕&零電阻，但任何工作。 Thx
