51 single chip digital tube serial communication [Copy link]

I want to ask whether the 51 single-chip microcomputer can realize that different digits of the digital tube light up different digits at the same time. If the serial communication is used to input numbers, can the digital tube light up specific digits?

Any microcontroller can implement it.

Yes, you can. You just need to send different lighting codes to the corresponding digital tubes. It is OK if you use the serial port.

How do you implement the delay? For example, if you implement it by counting variables, the microcontroller is not idle waiting, because it has a counting operation.
