How to turn on the oscilloscope of single chip microcomputer
When the single-chip microcomputer oscilloscope is opened, just connect the pin of the single-chip microcomputer to a channel port of the oscilloscope, and then run the simulation, the oscilloscope interface will automatically open. We can see that the orange line represents voltage. When it is at the top, the LED is turned on because of high voltage, and when it is at the bottom, the LED is turned off because of low voltage. The principle of using oscilloscope to troubleshoot problems is to identify whether there is a signal or not.

Oscilloscope is a visual signal that changes with time and can measure voltage with time.

Single chip microcomputer function

Single-chip microcomputer is an integrated circuit chip, which integrates the functions of CPU, RAM, ROM, various IO ports, interrupt system, timer and counter by VLSI technology, and has data processing ability.

It can also include display driving circuit, pulse width modulation circuit, analog multiplexer, A/D converter and other circuits integrated on a silicon chip to form a small and perfect microcomputer system, which is widely used in industrial control field. From the 1980s, from the then 4-bit and 8-bit single-chip microcomputer to the present 300M-meter high-speed single-chip microcomputer.
