#Bootcamp# Simple Oscilloscope Based on GD32 -- 5589055A

Overview

(1) Analog front-end processing circuit: responsible for processing the input detection analog signal and then giving it to the microcontroller for recognition. The specific circuit includes AC/DC coupling selection circuit, voltage attenuation circuit, and signal processing circuit.
(2) Power supply circuit: using the LCSC GD32E230C8T6 development board to convert 5V to 3.3V via LDO.
(3) Microcontroller part: directly using the LCSC GD32E230C8T6 development board to connect to the motherboard via a header.
(4) Human-machine interaction circuit: used to control the oscilloscope functions, including buttons, encoder, 1.8-inch TFT LCD screen, providing a foundation for the development of oscilloscope functions.

Measurement range: -80V — +250V.
Refer to the official case.
The oscilloscope can automatically capture the waveform, frequency, phase, etc. of the signal and present them on the display screen
to facilitate the analysis of the circuit working status.
