本代碼為編碼開關代碼,編碼開關也就是數(shù)字音響中的 360度旋轉的數(shù)字音量以及顯示器上用的(單鍵飛梭開 關)等類似鼠標滾輪的手動計數(shù)輸入設備。 我使用的編碼開關為5個引腳的,其中2個引腳為按下 轉輪開關(也就相當于鼠標中鍵)。另外3個引腳用來 檢測旋轉方向以及旋轉步數(shù)的檢測端。引腳分別為a,b,c b接地a,c分別接到P2.0和P2.1口并分別接兩個10K上拉 電阻,并且a,c需要分別對地接一個104的電容,否則 因為編碼開關的觸點抖動會引起輕微誤動作。本程序不 使用定時器,不占用中斷,不使用延時代碼,并對每個 細分步數(shù)進行判斷,避免一切誤動作,性能超級穩(wěn)定。 我使用的編碼器是APLS的EC11B可以參照附件的時序圖 編碼器控制流水燈最能說明問題,下面是以一段流水 燈來演示。

Particle swarm optimization (PSO) was originally designed and introduced by Eberhart and Kennedy (Ebarhart, Kennedy, 1995 Kennedy, Eberhart, 1995 Ebarhart, Kennedy, 2001). The PSO is a population based search algorithm based on the simulation of the social behavior of birds, bees or a school of fishes. This algorithm originally intends to graphically simulate the graceful and unpredictable choreography of a bird folk. Each individual within the swarm is represented by a vector in multidimensional search space.

The first edition of the book was one of the elements of my habilitation (a quali- fication above a Ph.D., which is a necessary step for obtaining the title of a professor in Poland and other European countries), and as a result it was subse- quently very carefully reviewed by four reviewers. The habilitation was a success. Using the insightful comments from my reviewers, I have improved the current version and eliminated some typographic errors that were initially overlooked.

針對目前使用的RS232接口數(shù)字化B超鍵盤存在PC主機啟動時不能設置BIOS,提出一種PS2鍵盤的設計方法。基于W78E052D單片機,采用8通道串行A/D轉換器設計了8個TGC電位器信息采集電路,電位器位置信息以鍵盤掃描碼序列形式發(fā)送,正交編碼器信號通過XC9536XL轉換為單片機可接收的中斷信號,軟件接收到中斷信息后等效處理成按鍵。結果表明,在滿足開機可設置BIOS同時,又可實現(xiàn)超聲特有功能,不需要專門設計驅動程序,接口簡單,成本低。 Abstract: Aiming at the problem of the digital ultrasonic diagnostic imaging system keyboard with RS232 interface currently used couldn?蒺t set the BIOS when the PC boot, this paper proposed a design method of PS2 keyboards. Based on W78E052D microcontroller,designed eight TGC potentiometers information acquisition circuit with 8-channel serial A/D converter, potentiometer position information sent out with keyboard scan code sequentially.The control circuit based on XC9536 CPLD is used for converting the mechanical actions of the encoders into the signals that can be identified by the MCU, software received interrupt information and equivalently treatmented as key. The results show that the BIOS can be set to meet the boot, ultrasound specific functionality can be achieved at the same time, it does not require specially designed driver,the interface is simple and low cost.
