Keyboard

鍵盤是最常用也是最主要的輸入設(shè)備，通過鍵盤，可以將英文字母、數(shù)字、標(biāo)點符號等輸入到計算機中，從而向計算機發(fā)出命令、輸入數(shù)據(jù)等。

基于瑞薩電子微控制器的溫度控制系統(tǒng)設(shè)計

　　為了提高傳統(tǒng)溫度控制系統(tǒng)的性能，將PID控制理論與嵌入式系統(tǒng)相結(jié)合，采用瑞薩電子公司的H8S/2166作為核心處理器，AD公司的AD7705以及熱敏電阻溫度傳感器作為溫度檢測單元，利用4×6小鍵盤、LCD顯示器和S1D13305液晶控制器達到良好的人機交互，設(shè)計出了一個應(yīng)用于化工領(lǐng)域的嵌入式實時溫度控制系統(tǒng)。相比于傳統(tǒng)溫度控制系統(tǒng)，該系統(tǒng)提供了更強的計算能力和可擴展能力，采用增量PID控制算法實現(xiàn)復(fù)雜控制。通過實驗，該系統(tǒng)能達到0.1 ℃的溫度控制精度以及小于120 s的溫度穩(wěn)定時間。　　Abstract: 　　In order to improve the performance of conventional temperature control system， combining PID control theory with embedded systems， using the Renesas Electronics Corp. H8S/2166 micro-controller as a core processors， AD7705 and thermistor temperature sensor as a temperature detection unit and 4×6 small Keyboard， LCD and S1D13305 LCD controller as a good human-computer interaction， this paper designed an embedded real-time temperature control system which is applied in chemical industry. Compared with conventional temperature control system， this system provides more computing power and extensibility， and adopts PID control algorithm for complex control. Through the experiment， the system can reach temperature control accuracy of 0.1 ℃ and temperature stabilization time of less than 120 seconds.

基于單片機的數(shù)字化B超鍵盤設(shè)計

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(shè)置BIOS，提出一種PS2鍵盤的設(shè)計方法?；赪78E052D單片機，采用8通道串行A/D轉(zhuǎn)換器設(shè)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(zhuǎn)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(jié)果表明，在滿足開機可設(shè)置BIOS同時，又可實現(xiàn)超聲特有功能，不需要專門設(shè)計驅(qū)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.
