Advances in scientific knowledge are increasingly supported by a growing community of developers freely sharing new hardware and software tools. In this spirit we have developed a free Android app, ABE-VIEW, that provides a flexible graphical user interface (GUI) populated entirely from a remote instrument by ascii-coded instructions communicated wirelessly over Bluetooth. Options include an interactive chart for plotting data in real time, up to 16 data fields, and virtual controls including buttons, numerical controls with user-defined range and resolution, and radio buttons which the user can use to send coded instructions back to the instrument. Data can be recorded into comma delimited files interactively at the user's discretion. Our original objective of the project was to make data acquisition and control for undergraduate engineering labs more modular and affordable, but we have also found that the tool is highly useful for rapidly testing novel sensor systems for iterative improvement. Here we document the operation of the app and syntax for communicating with it. We also illustrate its application in undergraduate engineering labs on dynamic systems modeling, as well as for identifying the source of harmonic distortion affecting electrochemical impedance measurements at certain frequencies in a novel wireless potentiostat.
科学知识的进步越来越依赖于一个不断壮大的开发者社区，他们自由地分享新的硬件和软件工具。本着这一精神，我们开发了一个免费的 Android 应用程序 ABE-VIEW，它提供了一个完全由远程仪器通过无线蓝牙传输的 ASCII 编码指令来填充的灵活图形用户界面 (GUI)。该应用程序具有多种功能，包括实时绘制数据的交互式图表、多达 16 个数据字段以及虚拟控件，如按钮、用户定义范围和分辨率的数值控件以及单选按钮，用户可以使用这些控件向仪器发送编码指令。用户可以根据需要随时将数据记录到逗号分隔的文件中。我们最初的项目目标是使本科工程实验室的数据采集和控制更加模块化和经济实惠，但我们也发现该工具对于快速测试新的传感器系统进行迭代改进非常有用。在这里，我们记录了该应用程序的操作和与之通信的语法。我们还展示了它在本科工程实验室中的应用，包括动态系统建模以及在新型无线电位计中确定在某些频率影响电化学阻抗测量的谐波失真源。
