This example demonstrates how to use the classic Bluetooth of ESP32 to read and write data from App created by App Inventor 2.
這個範例說明如何使用經典的藍芽連線方式，在ESP32開發版與App Inventor 2開發出來的 App間進行資料的讀寫。
1. Upload SerialToSerialBT code to ESP32 DevKitc_V4
2. Input string to the serial port monitor to transmit data to App.
3. Input a string to the Write Textbox and tap the Write Button in the App to send data to ESP32 board.
1. 上傳SerialToSerialBT.ino程式碼到ESP32 DevKitc_V4開發版
2. 在Arduino串列埠監控視窗輸入文字，傳送到App中。
3. 在App的 寫入文字方塊中輸入文字，按下寫入的按鈕，將資料傳輸到ESP32開發版上。
 
 
In the next video, I will demonstrate how to implement the classic bluetooth app by using App Inventor 2.
下一個影片，我們將展示如何使用App Inventor 2寫一個經典藍芽傳輸的App。
1. Start new project to create designer and blocks windows 開啟新專案建立designer與block視窗
2. Place ListPicker for displaying address and name of bluetooth and Label for showing the result of connection 放置ListPicker顯示藍芽的地址以及名稱，放置Label顯示藍芽連線的結果。
3. Place buttons and texboxes for reading and writing texts 放置讀與寫的按鈕以及文字區塊
4. Place a button for bluetooth disconnection 放置解除連線的按鈕
5. Pace bluetoothclient component 放置bluetoothclient元件
6. Use listpicker for the selection bluetooth device 使用ListPicker來選擇藍芽裝置
7. Connect the selected bluetooth device and set text and color of the connection label 與被選擇的裝置連線，並設定Connection Label的文字與顏色
8. Disonnect the selected bluetooth device and set text and color of the connection label 與被選擇的裝置解除連線，並設定Connection Label的文字與顏色
9. Write text to the selected bluetooth device 寫入文字到被選擇的藍芽裝置上
10. Recieve/read text from the selected bluetooth device 從被選擇的藍壓裝置收到/讀取文字
 

This example shows how to install Arduino extension and edit Arduino code in the VS code.
這個範例說明如何在VS Code中安裝Arduino extension以及編輯Arduino程式碼。
1. Install Arduino extension in the VS code.
在VS code中安裝Arduino extension。
2. Set Arduino installation Path.
設定 Arduino的安裝路徑。
3. Ctrl+Shift+P to input command " Arduino: Examples".
使用 Ctrl+Shift+P去輸入"Arduino: Examples"指令。
4. Open Blinky example
打開Blink的範例
5. Select COM port and board type "Mega2560".
選擇COM port, 以及Mega2560開發版。
6. Modify code and upload to Mega2560.
修改程式碼然後上傳到Mega2560上。

This example shows how to integrate a plot or figure on matplotlib into the graphic user interface of tkinter.
1. Import tkinter

This example shows how to use TouchGFX to design GUI on LCD of STM32F429I Disc1 Board.
One progress indicator and two buttons are used in this example.There are two examples of demonstrating interactions of the button to interact with the circleProgress indicator:

This example shows how to use "command" in button to call a function with or without parameters
1. Import tkinter

This example shows how to build a GUI by using tkinter.
1. Import tkinter

使用STM32Cube IDE在STM32F429-Disco開發板上撰寫程式控制LED閃爍。
This example shows how to use STM32Cube IDE to blink LED on STM32F429-Discovery kit.

This example provides the following three steps for training:
1. Install nidaqmx package, Python can use this package to read analog signals from NI DAQ card.
2. Use Simulated NI DAQ Device to simulate NI DAQ device.
3. Use matplotlib to plot analog signals from NI DAQ device.
這個範例提供以下三個步驟供練習:

這個範例說明如何將NI DAQ卡擷取的資料寫入檔案中
This example introduce how to write data acquired from NI DAQ card to a file.
這裡有5個步驟：
There are five steps:
1. Install nidaqmx package, Python can use this package to read analog signals from NI DAQ card. 2. Use Simulated NI DAQ Device to simulate NI DAQ device. 3. Use matplotlib to plot analog signals from NI DAQ device.
4. Use File open, write and close method to save a file.
5. Use "with open() as file" to save a file. This is a recommendation for file read and write in Python.
#1. 安裝nidaqmx套件，使用Pythone讀取NI DAQ類比訊號。

This example demonstrates how to build an actor framework project, create actor and message class, and launch actor to call message method.
這的範例展示了如何建立操作者框架專案，建立操作者與訊息類別，以及啟動操作者去呼叫訊息的方法。
The launch.vi uses old approach of Lauch Actor.vi before LabVIEW 2014. The new approach will use Launch Root Actor.vi.
在launch.vi中使用的是LabVIEW 2014年前所使用的Launch Actor.vi. 新的方法為使用Launch Root Actor.vi。
