After the program is started, the initial value of the timing is 15, and the data sent from the serial port (such as "99") can be used to modify the initial value of the next timing. #include STC89...[Details]

When using library functions such as printf, you need to write low-level functions such as _sys_exit(). For _sys_xxx and the like, just write an empty function. Functions like printf() use semihostin...[Details]

    Aiming at the drawbacks of the existing time switch devices on the market, this paper designs a time switch device based on STM32 processor. The device uses GSM network to realize remote control ...[Details]
