说明：  使用PIC微控制器设计汽车闭塞盒涉及利用MPLABIDE和XC8编译器。系统记录换档、记录数据等事件，并允许查看日志、更改密码和重置时间等功能。PIC微控制器与传感器接口以检测换档，将数据存储在非易失性存储器中。
(Designing a car block box with a PIC microcontroller involves utilizing MPLAB IDE and XC8 compiler. The system records events such as gear shifts, logs data, and allows functions like viewing logs, changing passwords, and resetting time. PIC microcontroller interfaces with sensors to detect gear shifts, storing data in non-volatile memory.)
