The MC68HC05K0 is a low cost, low pin countsingle chip microcomputer with 504 bytes of userROM and 32 bytes of RAM. The MC68HC05K0 isa member of the 68HC05K series of devices whichare available in 16-pin DIL or SOIC packages.It uses the same CPU as the other devices in the68HC05 family and has the same instructions andregisters. Additionally, the device has a 15-stagemulti-function timer and 10 general purposebi-directional I/0 lines. A mask option is availablefor software programmable pull-downs on all ofthe I/O pins and four of the pins are capable ofgenerating interrupts.The device is ideally suited for remote-controlkeyboard applications because the pull-downs andthe interrupt drivers on the port pins allowkeyboards to be built without any externalcomponents except the keys themselves. There isno need for external pull-up or pull-down resistors,or diodes for wired-OR interrupts, as these featuresare already designed into the device.

基于藥物治療在臨床治療中的重要性,分析目前服藥提醒裝置存在的不足,以STM32F103VET6單片機為控制核心,設計了一種多功能電子藥箱。該系統包括顯示模塊、語音模塊和數據存儲模塊。顯示模塊通過觸摸屏電路和LED指示燈電路,與語音模塊相配合,實現了服藥提醒及指導的功能;數據存儲模塊通過EEPROM存儲電路,能夠實現掉電時服藥信息不丟失的功能。并且為了實現電子藥箱的智能化控制,開發了手機APP,兩者之間可通過WIFI進行數據通信。經測試,該藥箱能夠有效地幫助慢性病患者按時、定量、正確服用藥物,適合在家庭中推廣使用,具有較高的應用價值和實踐意義。Based on the importance of drug therapy in clinical treatment, this paper analyzes the shortcomings of current drug reminder devices, and designs a multi-function electronic medicine box with STM32 F103 VET6 microcontroller as the control core. The system includes a display module, a voice module, and a data storage module. The display module cooperates with the voice module through the touch screen circuit and the LED indicator circuit to realize the function of reminding and guiding the medicine;the data storage module can realize the function of not losing the medication information when the power is off through the EEPROM storage circuit.After testing, the medicine box can effectively help chronic diseases patients to take drugs on time, in a quantitative and correct manner,and is suitable for popularization in the family, and has high application value and practical significance.
