中断实现LED数码管计数显示，通过外部中断实现LED数码管计数显示。要求两个外部中断分别控制十位，个位数码管，从零开始，每按下1次，计数增加1，到9再变成0.写出来代码

在嵌入式系统中，如使用Arduino Uno板，并利用INT0和INT1作为外部中断来控制LED数码管计数，你可以使用C语言编写这样的代码。这里是一个基本的示例，假设你已连接了数码管和外部中断按钮：

#include <LiquidCrystal.h> // Include the LiquidCrystal library for LCD display

// Define constants for LCD pins and interrupt pins
#define LCD_RS 8
#define LCD_EN 7
#define LCD_D4 4
#define LCD_D5 5
#define LCD_D6 6
#define LCD_D7 3

LiquidCrystal lcd(LCD_RS, LCD_EN, LCD_D4, LCD_D5, LCD_D6, LCD_D7); // Initialize LCD display

const int digitA = 9; // Pin for Digit A of LED display
const int digitB = 10; // Pin for Digit B of LED display

int count = 0; // Variable to store counting value
bool isInt0Pressed = false;
bool isInt1Pressed = false;

void setup() {
  lcd.begin(16, 2); // Initialize LCD with 16x2 characters
  pinMode(digitA, OUTPUT);
  pinMode(digitB, OUTPUT);

  attachInterrupt(digitalPinToInterrupt(INT0), incrementCounter, RISING); // Attach INT0 interrupt for digitA
  attachInterrupt(digitalPinToInterrupt(INT1), incrementCounterB, RISING); // Attach INT1 interrupt for digitB
}

void loop() {
  if (isInt0Pressed || isInt1Pressed) { // If any button is pressed
    clearDisplay(); // Clear the LCD
  }

  displayCount(); // Display the current count
}

void incrementCounter() {
  isInt0Pressed = true; // Set flag as button is pressed
  count++;
  if (count == 10) {
    count = 0; // Reset count when reaching 10
  }
  shiftDisplay(count / 10, digitA); // Shift digits to A for tens place
}

void incrementCounterB() {
  isInt1Pressed = true; // Set flag as button is pressed
  count++;
  if (count == 10) {
    count = 0; // Reset count when reaching 10
  }
  shiftDisplay(count % 10, digitB); // Shift digits to B for ones place
}

void clearDisplay() {
  lcd.clear();
}

void displayCount() {
  lcd.setCursor(0, 0);
  lcd.print("Count: ");
  lcd.setCursor(0, 1);
  if (count >= 10) {
    shiftDisplay(count / 10, digitA);
    shiftDisplay(count % 10, digitB);
  } else {
    shiftDisplay(count, digitA);
  }
}

void shiftDisplay(int num, int pin) {
  digitalWrite(pin, LOW); // Turn off previous digit
  delayMicroseconds(1); // Allow time for human eye perception
  while (num > 0) {
    digitalWrite(pin, HIGH); // Light up the appropriate segment for the number
    num--;
  }
}

请确保将INT0和INT1替换为你实际硬件对应的中断引脚，并调整数码管引脚以适应你的电路布局。运行此代码后，每当外部中断触发时，计数就会递增并在LCD上显示。
