我如何“重置"密码? Arduino开发板? [英] How can I "reset" an Arduino board?

问题描述

我已经将素描上传到了Arduino Uno，其循环类似于这个:

I've uploaded a sketch to an Arduino Uno whose loop is something like this:

void loop(){
    Serial.println("Hello, World!");
}

因此，现在，我无法再上传任何东西，因为IDE提示端口已在使用中".

So, now, I can't upload anything anymore, because the IDE says "port already in use".

有没有一种方法可以在没有其他程序员的情况下重置" Arduino?

Is there a way to "reset" the Arduino without another programmer?

没有其他东西在使用串行端口了，一切都很好，直到我上传了上一个草图.

Nothing else is using the serial port, and everything went just fine until I uploaded the previous sketch.

我发现了一些有趣的东西:

I've found some interesting things:

• 在Ubuntu 10.04 Lucid Lynx上出现0021的问题
• 回复:问题与在Ubuntu 10.04 Lucid Lynx上为0021
• 无法发送串行数据无法与串行监视器连接

推荐答案

尝试以下操作:

1. 准备基本的空程序(空设置，循环等)
2. 编译它.
3. 使用芯片上的硬件按钮重置Arduino
4. 按 Ctrl + U 上传代码.
5. 如果未成功-转到3.

1. Prepare the basic empty program (empty setup, loop, etc.)
2. Compile it.
3. Reset the Arduino using the hardware button on the chip
4. Press Ctrl + U to upload your code.
5. If unsuccessful - got to 3.

引导加载程序启动程序之前会有一个延迟，请根据您的时间进行操作.当我的Arduino代码中的错误每500毫秒执行一次软重置时，它为我工作.

There is a delay before the boot loader starts the programs, just work on your timing. It worked for me when a bug in my Arduino's code was executing a soft reset every 500 ms.
