我的愿望是通过USB端口（COM3-9600，N，8,1）与Arduino Uno通信。我打算在运行Windows 10的计算机上使用Autohotkey管理信息。
此测试仅用于读取Arduino的信息。但是后来我也希望能够从PC向Arduino Uno发送信息。
[Arduino Uno附加了一块卡（Funduino JoyStick Shield V1.A）-仅用于测试。
这是我在Arduino上使用的程序。：
// Armuino --- Funduino Joystick Shield --- // Playlist: https://www.youtube.com/playlist?list=PLRFnGJH1nJiKIpz_ZyaU-uAZOkMH8GAcw // // Part 1. Introduction - Basic Functions: https://www.youtube.com/watch?v=lZPZuBCFMH4 // Arduino digital pins associated with buttons const byte PIN_BUTTON_A = 2; const byte PIN_BUTTON_B = 3; const byte PIN_BUTTON_C = 4; const byte PIN_BUTTON_D = 5; const byte PIN_BUTTON_E = 6; const byte PIN_BUTTON_F = 7; // Arduino analog pins associated with joystick const byte PIN_ANALOG_X = 0; const byte PIN_ANALOG_Y = 1; void setup() { Serial.begin(9600); pinMode(PIN_BUTTON_B, INPUT); digitalWrite(PIN_BUTTON_B, HIGH); pinMode(PIN_BUTTON_E, INPUT); digitalWrite(PIN_BUTTON_E, HIGH); pinMode(PIN_BUTTON_C, INPUT); digitalWrite(PIN_BUTTON_C, HIGH); pinMode(PIN_BUTTON_D, INPUT); digitalWrite(PIN_BUTTON_D, HIGH); pinMode(PIN_BUTTON_A, INPUT); digitalWrite(PIN_BUTTON_A, HIGH); } void loop() { Serial.print("Buttons A:"); Serial.print(digitalRead(PIN_BUTTON_A)); Serial.print(" "); Serial.print("B:"); Serial.print(digitalRead(PIN_BUTTON_B)); Serial.print(" "); Serial.print("C:"); Serial.print(digitalRead(PIN_BUTTON_C)); Serial.print(" "); Serial.print("D:"); Serial.print(digitalRead(PIN_BUTTON_D)); Serial.print(" "); Serial.print("E:"); Serial.print(digitalRead(PIN_BUTTON_E)); Serial.print(" "); Serial.print("F:"); Serial.print(digitalRead(PIN_BUTTON_F)); Serial.print(" -- "); Serial.print("Position X:"); Serial.print(analogRead(PIN_ANALOG_X)); Serial.print(" "); Serial.print("Y:"); Serial.print(analogRead(PIN_ANALOG_Y)); Serial.print(" "); Serial.println(); delay(1000); }当我在PC上运行Arduino串行编辑器时，该程序似乎可以运行。值在屏幕上逐行显示，例如。：
**00:58:44.434 -> Buttons A:1 B:1 C:1 D:1 E:1 F:1 -- Position X:334 Y:321** (I can't see any wrong values in the Serial Editor. - maybe in higher speed)但是，如果我尝试使用Autohotkey“执行相同的操作，有时字符可能会丢失。
喜欢这个。：
But:322 Buttons A:1 B:1 C:1 D:1 E:1 F:1 -- Position X:334 Y:322 334 Y:322 Buttons A:1 B:1 C:1 D:1 E:1 F:1 -- Position X:334 Y:322我不知道在Windows 10中与USB的通信应如何。（我认为它与Windows XP不同）我已经看过这个解决方案了：Arduino + AutoHotKey > Serial Connection-不确定我找到了正确的Arduino.ahk-可能需要Windows XP？-对我不起作用！
此技巧更好（但较旧）。： Arduino.ahk beta .01
[大多数测试都基于此链接，并且我创建了以下AHK程序。：
#NoEnv ; Recommended for performance and compatibility with future AutoHotkey releases.
; #Warn ; Enable warnings to assist with detecting common errors.
SendMode Input ; Recommended for new scripts due to its superior speed and reliability.
