我对 C++ 编程世界还是很陌生，所以请放轻松。哈哈

我试图建立一个系统来跟踪我父亲最喜欢的游戏之一的高分。我正在使用 LCD 屏幕和 3x4 键盘来输入乐谱。我想在键盘上添加一个多击功能，这样它就好像它是一个用于存储用户首字母的电话键盘。我创建了一个用于存储分数的函数（它可能不是最好的方法，但它有效，非常感谢您对如何改进的评论。）我什至不知道从哪里开始。我已经查看了 Arduino 键盘库中的动态键盘示例，但我觉得我可能已经咬得比我能咀嚼的更多，我的代码如下：

#include <SoftwareSerial.h>
#include "Keypad.h"

// Create a software serial port!
SoftwareSerial lcd = SoftwareSerial(11,10); 
char scoreinput[] = {' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' '};
int counter = -2;
int counter2=0;
uint8_t red, green, blue;



const byte ROWS = 4; //four rows
const byte COLS = 3; //three columns
char keys[ROWS][COLS] = {
{'1','2','3'},
{'4','5','6'},
{'7','8','9'},
{'*','0','#'}
};
byte rowPins[ROWS] = {5, 6, 7, 8}; //connect to the row pinouts of the keypad
byte colPins[COLS] = {2, 3, 4}; //connect to the column pinouts of the keypad

Keypad keypad = Keypad( makeKeymap(keys), rowPins, colPins, ROWS, COLS );


void setup() {
lcd.begin(9600); 
Serial.begin(9600);

lcd.write(0xFE); //clear display 
lcd.write(0x58);
delay(10);
lcd.print("****PinScore*******************");
lcd.write(0xFE);//set cursor at home
lcd.write(0x48);
delay(5000);



lcd.write(0xFE); //clear display 
lcd.write(0x58);
delay(10);
lcd.print("New High Score?");
lcd.write(0xFE);
lcd.write(0x47);
lcd.write((uint8_t)2);
lcd.print(" Press      \"#\"");
delay(5000);

lcd.write(0xFE); //clear display 
lcd.write(0x58);
delay(10);
lcd.print("Display Scores?");
lcd.write(0xFE);
lcd.write(0x47);
lcd.write((uint8_t)2);
lcd.print(" Press      \"*\"");
delay(5000);

lcd.write(0xFE); //clear display 
lcd.write(0x58);
lcd.print("     Press     ");
lcd.write(0xFE);
lcd.write(0x47);
lcd.write((uint8_t)2);
lcd.print(" \"*\"   or  \"#\" ");
}


void loop() {



char key = keypad.getKey();

if (key != NO_KEY){
Serial.print(key);
lcd.print(key);
counter++;
counter2++;
scoreinput[counter]=(key);
}

switch (key == '#'){
   case 1:




lcd.write(0xFE); //clear display 
lcd.write(0x58);
delay(10);
lcd.print("Enter Your New  High Score");
delay(3000);
lcd.write(0xFE); //clear display 
lcd.write(0x58);
lcd.print("Press \"#\" At Any Time To Reset");
delay(3000);
lcd.write(0xFE); //clear display 
lcd.write(0x58);
lcd.print("Enter High Score:");


lcd.write(0xFE);
lcd.write(0x47);
lcd.write((uint8_t)18);
lcd.print(key);

if (counter==8){
  break;
}
}

if (counter==8){
lcd.write(0xFE); //clear display 
lcd.write(0x58);
delay(1000);
lcd.print(scoreinput[0]);
lcd.print(scoreinput[1]);
lcd.print(scoreinput[2]);
lcd.print(",");
lcd.print(scoreinput[3]);
lcd.print(scoreinput[4]);
lcd.print(scoreinput[5]);
lcd.print(",");
lcd.print(scoreinput[6]);
lcd.print(scoreinput[7]);
lcd.print(scoreinput[8]);
counter=-2;
delay(3000);
lcd.write(0xFE); //clear display 
lcd.write(0x58);
lcd.print("Enter your      Initals:");
  }
while (counter2>10){
if (key == '2'){
//this is where the multi tap function would be called to allow users to enter their intials 

}
}

您只需要一个计时器来测量自上次按键输入以来的时间。如果距离最后一次击键已经超过一定时间（可能是 1 秒），或者如果键与最后按下的键不同，则输入一个新字符（键的第一个字符；2=A，3=D等）否则它会增加字符（使用环绕，A=>B，B=>C，C=>A）。所以“234”进入“ADG”，“222”进入“C”，但“2(delay)22”进入“AB”。
