[Arduino] [Visual Studio] - 使用 Visual Studio 取代 Arduino 原廠 IDE

最近上 CodePlex 看了看，找到了這功能強大的插件 「Arduino for Visual Studio and Atmel Studio」，它使我能擺脫以前難用的原廠 Arduino IDE ，且支援 Arduino 所有的板子、Serial Monitor、ISP、Bootloader‎，並將 Visual Studio 的特色融入其中，使在開發 Adruino 時也能兼具原本 Visial Studio 的撰寫環境，值得推薦！

Arduino for Visual Studio and Atmel Studio

下載位置：
CodePlex： http://visualmicro.codeplex.com/


安裝使用步驟：
當然，使用 Visual Studio 替代原廠 IDE 必須要有 Visual Studio 才能使用，我這邊使用的是 2012 版本。插件也要求使用者需安裝 Arduino 原廠的 IDE ，有支援 1.0.X 和 1.5.X，我這邊使用的是1.0.5版本。

1.下載並安裝程式檔案，下載連結在上方

2.啟動 Visual Studio ，並會看到多出了個似廣告的視窗，我們先不管它並繼續使用 free trail (試用版本)。選擇 free trail

3.選擇目前使用的 Arduino IDE 版本，並設定目前 Arduino IDE 的安裝路徑，另外 sketchbook 就看要不要填，我這邊是空著它。選擇 OK

4.如需新增一個 Arduino 專案，到 「檔案」->「新增」選擇「Sketch Project」後填入專案名稱並新增一個新的 Arduino 專案


以上安裝步驟概述完畢，但是寫完自己的程式總需要把程式燒錄至 Arduino ，對吧？
沒錯，不用想得太複雜，只需按下 F5 ，Arduino 專案會自己編譯後將程式燒錄至指定的 Serial Port。

*選擇 Arduino 板子類型，請在 Visual Studio 工具列上找到有 Arduino XXXX 的下拉式選單來選取
*選擇要燒錄的 Serial Port ，請在 Visual Studio 工具列上找到有 COMXX 的下拉式選單來選取
*使用 Serial Monitor，它就在選擇 Serial Port 下拉是選單的右方，點該按鈕即可叫出
