If you use this routine,

1) must use STC12C5A60S2 single chip microcomputer.

2) must use the 11.0592M crystal.


If you use other single chip, such as STM32, don't tube above two points, as long as the serial baud rate adjusted to 115200.


(Note, STC89C52 microcontroller can not be used, because the speed is not up to.)
