  • 基于MSP430F5529单片机综合实验装置的研制

    针对目前MSP430单片机实验装置较少、实验内容少,而且无MSP430高端产品的实验装置,研制了基于MSP430F5529单片机的综合实验装置,主要包括MSP430 Launch Pad和母板两部分。较传统的单片机实验装置增加了模拟电路的设置,设计的实验能够利用单片机的所有外设,可进行模块基础实验和综合实验两大类实验,非常适合自动化和电气信息类大学生学习使用。Concerning with the lack of experimental equipment and content based on MSP430,and especially,the experimental equipment of MSP430 senior products,an experimental equipment based on MSP430F5529 microcontroller is developed. It mainly consists of two parts: MSP430 Launch Pad and main board. Compared with traditional microcontroller experiment equipment,a few analog circuits were added. The experiment we set up takes advantage of all microcontroller peripherals. Students can do two kinds of experiments: module experiment and complex experiment.Therefore it fits university students in automation and electrical major very well.

  • 基于蓝牙技术的汽车OBDⅡ接口

    OBD(On-Board Diagnostics),即随车诊断系统,可以通过汽车上安装的随车诊断装置,实时监测汽车的运行状况。美国汽车工程师协会(SAE)制定的汽车OBD 1随车诊断系统,统一了故障诊断接口和故障代码的设置及含义。随车诊断系统的不足之处是只能提供某一特征故障的故障代码与某些故障数据,不能对维修人员给以更具体的指导。一种比较有效的解决方案是将专家系统与随车诊断系统相结合,设计出一种集故障代码与故障数据的采集、逻辑判断与维修指导为一体的,并具备用户经验知识库扩充功能的计算机辅助诊断系统,能方便地指导维修人员较迅速、准确地找出电控汽车故障原因,从而提高汽车维修效率。[1]目前,OBD11随车诊断系统的连接器采用SAEJ1962标准的16引脚插座,数字信号主要采用ISO9141和SAEJ 1850规定的电平信号编码,读取诊断信息必须通过专用的OBD 11电缆及接口。利用蓝牙技术,将OBD11接口的电平编码进行无线电传输,不仅方便了OBD11随车诊断系统的信息交换,也将大大扩展OBD11随车诊断系统的应用领域。

  • 如何利用TI的UltraLibrarian软件生成Allegro封装

    1、安装完成后,点击Continue Free,进入下一步。2、如上图依次点击1-4,选择下图所示从TI官网下载的封装文件,导出所需软件的封装配置文件。注:这里导出的还只是配置文件,需再做一些操作才能生成Allegro的原件库文件。3、导出文件后,配置文件会自动尝试生成原件封装,但是肯定会失败。这时需要把自动打开的txt文件中如上所示的路径添加到Allegro中.4、双击上图自动生成的blank Board.Brd.如下图所示,依次把txt中的路径添加到Scriptpath,Padpath,psppath中。5、双击2019-05-22-17-33-23.bat,然后,一路确认下去。结束,下面箭头所指文件就是我们所要的元件封装了。当然,其他pad,Flash文件也要复制到相应的库路径里。
