針對目前使用的RS232接口數(shù)字化B超鍵盤存在PC主機(jī)啟動時不能設(shè)置BIOS,提出一種PS2鍵盤的設(shè)計方法。基于W78E052D單片機(jī),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(jī)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(jī)可設(shè)置BIOS同時,又可實(shí)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.
