針對目前MSP430單片機實驗裝置較少、實驗內容少,而且無MSP430高端產品的實驗裝置,研制了基于MSP430F5529單片機的綜合實驗裝置,主要包括MSP430 Launch Pad和母板兩部分。較傳統的單片機實驗裝置增加了模擬電路的設置,設計的實驗能夠利用單片機的所有外設,可進行模塊基礎實驗和綜合實驗兩大類實驗,非常適合自動化和電氣信息類大學生學習使用。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.

OBD(On-Board Diagnostics),即隨車診斷系統,可以通過汽車上安裝的隨車診斷裝置,實時監測汽車的運行狀況。美國汽車工程師協會(SAE)制定的汽車OBD 1隨車診斷系統,統一了故障診斷接口和故障代碼的設置及含義。隨車診斷系統的不足之處是只能提供某一特征故障的故障代碼與某些故障數據,不能對維修人員給以更具體的指導。一種比較有效的解決方案是將專家系統與隨車診斷系統相結合,設計出一種集故障代碼與故障數據的采集、邏輯判斷與維修指導為一體的,并具備用戶經驗知識庫擴充功能的計算機輔助診斷系統,能方便地指導維修人員較迅速、準確地找出電控汽車故障原因,從而提高汽車維修效率。[1]目前,OBD11隨車診斷系統的連接器采用SAEJ1962標準的16引腳插座,數字信號主要采用ISO9141和SAEJ 1850規定的電平信號編碼,讀取診斷信息必須通過專用的OBD 11電纜及接口。利用藍牙技術,將OBD11接口的電平編碼進行無線電傳輸,不僅方便了OBD11隨車診斷系統的信息交換,也將大大擴展OBD11隨車診斷系統的應用領域。

1、安裝完成后,點擊Continue Free,進入下一步。2、如上圖依次點擊1-4,選擇下圖所示從TI官網下載的封裝文件,導出所需軟件的封裝配置文件。注:這里導出的還只是配置文件,需再做一些操作才能生成Allegro的原件庫文件。3、導出文件后,配置文件會自動嘗試生成原件封裝,但是肯定會失敗。這時需要把自動打開的txt文件中如上所示的路徑添加到Allegro中.4、雙擊上圖自動生成的blank Board.Brd.如下圖所示,依次把txt中的路徑添加到Scriptpath,Padpath,psppath中。5、雙擊2019-05-22-17-33-23.bat,然后,一路確認下去。結束,下面箭頭所指文件就是我們所要的元件封裝了。當然,其他pad,Flash文件也要復制到相應的庫路徑里。
