摘要在数字电路实验中,需要使用若干仪器、仪表观察实验现象和结果。而示波器在电子、电气、控制等领域应用十分广泛。但市场现有的数字示波器有诸多不足,如价格昂贵、体积重量偏大、携带不方便等,而齐全的功能在很多的场合并不一定能够得到充分的应用。
本文设计的手机软件能配合具有数据采集、AD转换并能通过蓝牙发送数据的虚拟示波器模块使用,通过蓝牙与硬件无线通信,获取波形信号、电压电阻信号等采集到的数据并在手机面板上显示。
本文详细地介绍了基于蓝牙的手机虚拟示波器的原作原理及技术特点,接着给出了软件的设想和思路。软件设计方面,主要研究了手机蓝牙的各项设置、连接其他蓝牙设备以及波形的绘制。通过具体的开发设计,解决了手机和装有蓝牙模块的单片机设备的连接以及在手机屏幕实时绘制波形等实际问题,基本实现了本文的设计目标。20672

Title Virtual oscilloscope software design based on Bluetooth smartphone
Abstract
The digital circuit experiment requires a number of instruments and meters to observe the experimental phenomena and results. The oscilloscope in the electronic, electrical, control and other fields is widely used. But the existing market digital oscilloscope has many inadequacies, such as the exorbitant price, larger volume and weight, lack of portability, etc. , and some of lengthy and jumbled functions may not necessarily fully applied in many occasions.
The mobile software designed in this article can be used with the virtual oscilloscope module which have some function of data acquisition, AD conversion and sending the data via Bluetooth. It carries out wireless communication with the hardware via Bluetooth to acquire data collected on wave signal, Voltage resistance signal etc and display on the phonepanel.
The operating principle and technical features of the Bluetooth-based mobile phone virtual oscilloscope are introduced in detail. The linked article continues with the thinking and tentative idea of software. In the software design, the focus is mainly on the various settings of Bluetooth of cell phone, attachment of other Bluetooth devices and the drawing of wave . Through specific development and design, the connection of mobile phone and SCM(single chip micyoco) equipped with Bluetooth module and wave real-time drawing on the phone screen and so forth are solved. As a consequence of this, the article's design goals are basically realized.
