本软件所实现的功能是：单片机检测按键的输入信息，并实时地显示在LCD1

The function realized by the software is: the single-chip computer detects the input information of the keys and displays it on the LCD1602 in real time. The system records the medication time 3 times. After the system clock is adjusted, the system starts to run. During the operation, the time has come. Afterwards, the voice chip performs voice broadcast, and judges whether the infrared obstacle avoidance module has been blocked, and if the block indicates that someone wants to cancel the voice broadcast. The structure of each program module is shown in Figure 4-1:

The function of this software is: the single chip detection key input information, and real-time display on LCD1602, in the system record3 times the use of time, adjust the system clock after the system began to run, in the course of operation, to the time after the voice chip voice broadcast, and judge whether the infrared barrier prevention module to block, if the mask indicates that someone to cancel the voice. The structure of each program module is shown in Figure 4-1:

The function of this software is: the single chip microcomputer detects the input information of the key, and displays it on LCD1602 in real time. The system records three times of medication time in the system. After adjusting the system clock, the system starts to run. In the process of running, the voice chip broadcasts the voice after the time, and judges whether the infrared obstacle avoidance module is blocked. If the blocking indicates that someone has to go, then Cancel voice broadcast. The structure of each program module is shown in Figure 4-1:<br>
