How does arduino temporarily store the result of each scan and press the button to print it

If your scan function void scan() already gets the data it needs correctly and stores it in an array, Then you can use the array directly in the loop() function without having to call analogRead() again to get the data.

You can declare the scanResults array as a global variable so that it can be accessed in the loop() function. In the loop() function, when the counter scanCounter reaches 3, you can do subsequent operations directly with the data in the scanResults array instead of calling the void scan() function again.

Here is an example of the modified code:

// 定义存储扫描结果的数组和计数器
int scanResults[3];
int scanCounter = 0;

void setup() {
  Serial.begin(9600); // 初始化串口通信
}

void loop() {
  // 扫描数据并存储到数组中
  scan(); // 假设您的扫描函数为 void scan()
  scanCounter++;
  
  // 检查是否已经扫描了3次
  if (scanCounter == 3) {
    scanCounter = 0; // 重置计数器
    
    // 等待按键按下
    while (digitalRead(2) == HIGH) {
      delay(10);
    }
    
    // 按键按下后打印数据
    Serial.print("Scan results: ");
    for (int i = 0; i < 3; i++) {
      Serial.print(scanResults[i]);
      Serial.print(" ");
    }
    Serial.println();
    
    // 等待按键释放
    while (digitalRead(2) == LOW) {
      delay(10);
    }
  }
}

Note that in the code example above, the void scan() function needs to be defined and implemented before the loop() function. Also, because the scanResults and scanCounter arrays are global variables, they need to be declared outside of the setup() function.

Here is a complete code example of a simple C# console application for storing and printing scan data:

using System;
using System.Collections.Generic;

namespace ScanDataStorage
{
    class Program
    {
        static List<string> scannedData = new List<string>();

        static void Main(string[] args)
        {
            Console.WriteLine("请扫描数据，按q退出程序：");

            while (true)
            {
                string input = Console.ReadLine();

                if (input == "q") break;

                scannedData.Add(input);
                Console.WriteLine($"已存储 {scannedData.Count} 条数据");
            }

            Console.WriteLine("按p打印存储的数据：");
            while (Console.ReadKey().Key == ConsoleKey.P)
            {
                Console.WriteLine("\n--- 开始打印数据 ---");
                foreach (string data in scannedData)
                {
                    Console.WriteLine(data);
                }
                Console.WriteLine("--- 数据打印完成 ---\n");
                Console.WriteLine("按p继续打印，按其他键退出");
            }
        }
    }
}

You can use Arduino arrays and loops to do this using GPT and your own ideas. Here is a simple example code:

// 定义存储扫描结果的数组和计数器
int scanResults[3];
int scanCounter = 0;

void setup() {
  Serial.begin(9600); // 初始化串口通信
}

void loop() {
  // 扫描数据并存储到数组中
  int scanData = analogRead(A0); // 假设这里是模拟输入
  scanResults[scanCounter] = scanData;
  scanCounter++;
  
  // 检查是否已经扫描了3次
  if (scanCounter == 3) {
    scanCounter = 0; // 重置计数器
    
    // 等待按键按下
    while (digitalRead(2) == HIGH) {
      delay(10);
    }
    
    // 按键按下后打印数据
    Serial.print("Scan results: ");
    for (int i = 0; i < 3; i++) {
      Serial.print(scanResults[i]);
      Serial.print(" ");
    }
    Serial.println();
    
    // 等待按键释放
    while (digitalRead(2) == LOW) {
      delay(10);
    }
  }
}

This example code assumes that port A0 is used for analog scanning and key is used for digital port 2. Each scan stores the results into an array of length 3. After scanning for 3 times, wait for the key to be pressed.
