Use Refnum (point) to read/write data transfer 3. Use dynamic event to send data 這個視頻說明如何在LabVIEW使用佇列訊息處理器的設計模式來撰寫程式，包含： 1. 建立專案時使用QMH模板 2. 使用參考(指標)讀寫數據 3. 使用動態事件傳遞數據

由於在更新LabVIEW 2021後，Vision Development Module (VDM)也要更新到2021年版，在NI的網站無法下載到軟體，因此我使用NI Package Manager來安裝VDM軟體。 安裝的過程如下:

This video shows how to use mathematical functions in LabVIEW and Python. We introduce Expression Node for non-conplex data type calculation in LabVIEW and applications of Math library in Python. Some examples (conversion of degree and radian, the plot of sine wave etc.) are provided for the demonstration of Expression Node and Math library in LabVIEW and Python respectively. 本視頻說明如何在LabVIEW和Python中使用數學函數。 我們介紹LabVIEW的Expression Node來處理簡單的資料型態，以及Math函數庫在Python中的應用。 我們也提供的一些範例，如角度與弧度間的轉換、Sine波的繪製，來說明Expression Node和Math函數庫分別在與Python中應用。 References: 1.

將LabVIEW更新到2014版後，新買的BLE Dongle也到貨了，接下來要完成LabVIEW BLE Toolkit的安裝，以及BLE Dongle Driver的安裝。 使用VIPM安裝完BLE Toolkit，接著按下Show Examples按鈕，      可選擇以下三個VI來測試，      ble_scan_devices.vi Discover and connect to BLE devices ble_read_write_characteristics.vi Read and Write a Characteristic value, providing the  UUID  for  Service  and  Characteristic ble_read_hr_monitor.vi  Acquire Heart Rate data stream, for devices with Heart Rate Profile 執行 ble_read_hr_monitor.vi，

之前使用過 App inventor開發過BLE App，但實在是有不方便的地方 例如Debug的部分， 最近翔從 LabVIE來實現與BLE的溝通，於是搜尋相關資訊，發現LabVIEW有提供相關的套件， 1. 下載資訊: Communicate with Bluetooth Low Energy (BLE) Devices in LabVIEW https://knowledge.ni.com/KnowledgeArticleDetails?id=kA00Z0000019LuHSAU 2. 低功耗藍芽工具套件下載處 BLE-Toolkit-LabVIEWriu https://github.com/MuSAELab/BLE-Toolkit-LabVIEW 3. 使用VIPM安裝 套件內容: BLE Toolkit v1.4.0.2 by MuSAE Lab Author: Raymundo Cassani Copyright: Copyright (c) 2017, MuSAE Lab License: MIT Compatible LabVIEW Versions: >= 2013.
