I am in couldn't figure out how to implement this function

CodePudding user response:

Serial port can be the PC to the serial port to send data, single-chip microcomputer serial port to collect data to judge the IO

CodePudding user response:

Don't understand, it is not PC software, or won't single-chip microcomputer software?

CodePudding user response:

To the single-chip microcomputer with a SSH

Joke out

Topic: how to learn a serial port work, secondly to learn a good you use of single-chip microcomputer serial port function on how register work, register what, how to do, and finally, if there is a function of how routine, learn to register, but it is better to library function, no library, can directly use the register,

The above is the "self study method" to solve the problem of your
