本次设计实现了一种低功耗手持式数据记录仪,本文主要介绍仪器的主要组成部分。然后再分别对该记录仪的硬件系统和软件系统进行了具体的介绍,进行对该类记录仪进行不同模块的分析。可以通过无线系统对外来的数据进行记录并利用上位机的模块和电脑的连接将记录的数据传入电脑利用图形对结果进行分析。设计方案利用MSP430单片机开发板结合4*4键盘、单色点阵LCD,利用软件系统对硬件进行控制,同时通过无线模块对数据进行了传输进行记录,还通过上位机接口实现了MSP430单片机和计算机之间的通讯,也可以通过触摸屏或者键盘的按键操作对LCD显示屏进行操作以实现记录的存储和显示。通过实验调试过程和结果的说明,了解这个实验结果是通过什么实现的。最后说明这次实验的完成情况,同时对该记录仪的一些可开发功能进行说明。 This design implements a low-power handheld data logger, this article describes the main components of the instrument. And then the recorder’s hardware system and software system were described in detail, for this type of recorder for different modules of the analysis. The wireless system can record foreign data and use the PC’s module and computer connection to record the data into the computer to analyze the results using graphics. Design using MSP430 microcontroller development board with 4 * 4 keyboard, monochrome dot-matrix LCD, the use of software systems to control the hardware, at the same time through the wireless module for data transmission records, but also through the host computer interface MSP430 microcontroller and computer Between the communication, but also through the touch screen or keyboard keys on the LCD screen to operate in order to achieve the record of storage and display. Through the experimental debugging process and the results of the instructions to understand the experimental results through what is achieved. Finally, the completion of this experiment, at the same time some of the recorder can be developed to illustrate.
