#7th LCSC Electronics Contest# MiniDSO (Simple Digital Storage Oscilloscope)

Note: * Required fields,
please fill them in during the registration phase ↓
 
* 1. Project Function Introduction
This is a mini oscilloscope based on the National Technology N32G430C8L7 MCU. Key features include: small size, low cost, and simple operation, suitable for applications where size and cost are critical and signal measurement accuracy is not critical. Examples include: electronics DIY, student dormitories, and inspection and repair of outdoor electronic equipment.
The oscilloscope includes two signal input channels that can acquire and display two signals on an LCD screen for easy observation and comparison.
It also includes one signal output channel capable of generating sine waves, square waves, sawtooth waves, and triangle waves.
The oscilloscope uses pin headers to bring out power pins, which can be used to power other devices or as a breadboard power supply when needed. (The oscilloscope does not have a battery and requires USB power. A battery-powered version will be released later.)
 
*2. Project Attributes This is

Please fill in the relevant information during the competition stage. ↓
 
* 4. Hardware:
MCU connects to power supply, crystal oscillator, LCD, user buttons, potentiometer, BOOT button, reset button, debug interface, and signal input/output interface.
The MCU collects and stores input signals, then displays them on the LCD screen.
Users can control the MCU's operating status using independent buttons and a dial potentiometer.
Detailed circuit diagrams can be found in the schematic.
