如何重置我的Arduino Mega2560与我的C＃应用​​程序？ [英] How do I reset my Arduino Mega2560 with my C# application?

问题描述

我注意到Arduino的IDE自动在启动/退出复位内置串行应用，由于

I noticed the Arduino IDE automatically resets on startup/exit by the built in serial application due to

FT232RL的硬件流控制线（DTR）中的一个连接到经由100纳法电容器ATmega1280的复位线。当这条线被置（取低），复位线降到足够长的复位芯片。

one of the hardware flow control lines (DTR) of the FT232RL is connected to the reset line of the ATmega1280 via a 100 nanofarad capacitor. When this line is asserted (taken low), the reset line drops long enough to reset the chip.

我注意到的行为不符合我的序列C＃应用程序发生。我想重置功能与我的C＃应用​​程序的工作。什么我没有做让我的Arduino米加我的C＃应用​​程序重置？

I noticed that behaviour does not happen with my serial C# application. I would like the reset feature to work with my C# application. What am I not doing to get my Arduino Mega to reset by my C# application?

工作code代表的Arduino和C＃：

我把它从PWM Port12电线钩住到RESET港约5分钟的工作。 Arduino上，我检查对传入的SerialEvent3文本RESET。当RESET发现做的：

I got it working in about 5 minutes by hooking up a wire from PWM Port12 to the RESET Port. On the Arduino, I checked for the text RESET on the incoming SerialEvent3. When RESET is found do:

pinMode(7, OUTPUT);  
digitalWrite(7, LOW);

至于为C＃这是简单的：

As for as the C# it was as simple as:

if (serialPort1.IsOpen)
{ 
    serialPort1.Write("RESET"); 
}

复位似乎按预期方式工作。

Reset seems to work as expected.

推荐答案

DTR工作正常，我从.NET SerialPort类。

DTR works fine for me from the .NET SerialPort class.

刚刚成立的属性：

port.DtrEnable = true;

我已经注意到不同的默认值，如果你在的WinForms设计师使用的SerialPort，但 DtrEnable 其实是在真正从一个控制台应用程序使用时（默认情况下）。

I have noticed different defaults if you use the SerialPort in the WinForms designer, but DtrEnable is in fact true (by default) when using it from a console app.
