#The 7th Lichuang Electric Competition#Simple digital storage oscilloscope oscilloscope_MiniDSO

Note: * is a required field,
please fill it in during the registration stage↓
 
* 1. Project function introduction
A mini oscilloscope based on the National Technology N32G430C8L7 MCU. The main features are: small size, low cost, simple operation, suitable for use in scenarios that are sensitive to size and cost and do not require high signal measurement accuracy. For example: electronic DIY, student dormitories, inspection and repair of outdoor electronic equipment.
The oscilloscope contains two signal input channels that can collect two signals and display them on the LCD screen respectively, making it convenient for users to observe and compare signals.
The oscilloscope contains a signal output channel, which can generate sine waves, square waves, sawtooth waves and triangle waves.
The oscilloscope leads out the power pin through a pin header. When necessary, the power lead pin of the oscilloscope can be used to power other devices or as a breadboard power supply. (The oscilloscope has no battery and needs to be powered by USB. A version with a battery will be updated later.)

MIT during the competition stage↓ *4. Hardware part MCU connects power supply, crystal oscillator, LCD, user button, potentiometer, BOOT button, reset button, debug interface and signal input and output interface. MCU collects and stores input signals, and then displays them on the LCD screen. Users can control the working state of MCU through independent buttons and dial potentiometers. Please see the schematic diagram for detailed circuit diagram. The schematic diagram of the circuit structure is as follows: The actual circuit diagram is as follows: *5. Software part GUI part is as follows: See attachment for details. *6. BOM list *7. Competition LOGO verification * 8. Demonstrate your project and record it as a video and upload it .
