Electronic calendar function to enumerate

A list of calendar functions, such as: basic calendar (FUN_CLOCK), alarm clock (FUN_ALARM), schedule (FUN_SCHEDULE), modification time (FUN_CHANGE_TIME) and small game (FUN_CATCH_RABBIT). Abstract data type fun_t.

typedef enum {  // 功能判断
    FUN_CLOCK = 0,
    FUN_ALARM,
    FUN_SCHEDULE,
    FUN_CHANGE_TIME,
    FUN_CATCH_RABBIT,
    FUN_BUTT
} fun_t;

Function Switch

By switching function keys KEY_FUN completed, KEY_FUN key press is detected, switching to the next operating mode.

The main function

Responsible for initializing the various hardware modules, microcontroller 51 initializes the internal system, then the mapping cyclic scanning matrix keyboard and function keys to the key value, to do alarm, schedule reminders detection, complete the switching function.
