Mini-DSO - a low-cost simple oscilloscope

A simple oscilloscope made of STC8A8K MCU. The microcontroller uses STC8A8K64S4A12 working at 27MHz. The display uses a 0.96 OLED with a resolution of 128x64. This oscilloscope project is easy to start and covers the necessary measurement functions. Supports normal mode, single mode, and automatic mode. It has trigger mode selection, such as level trigger, and comes with saved settings. Mini-DSO input is single-channel mode, and the second/division size can support a variety of: 500ms, 200ms, 100ms, 50ms, 20ms, 10ms, 5ms, 2ms, 1ms, 500us, 200us, 100us, and the voltage acquisition range is 0 to 30V. The sampling rate can reach 250kHz@100us/div.

Pocket oscilloscope source code based on STM32, has been tested and passed

Solemn statement: This is an open source product and can only be used for learning and communication. Commercial use is strictly prohibited, otherwise we will pursue legal liability. Your use of our source code indicates your acceptance of this statement. Qdso is a well-designed pocket oscilloscope with 40M bandwidth, 200M sampling rate and 3.5-inch TFT color screen. The overall design controller uses nios ii soft core; AD9288-100 cross sampling rate reaches 200M real-time sampling, and the display part uses RA8872 that supports double buffering and 2D drawing acceleration to achieve high-speed waveform drawing and display. And we will make the source code and detailed tutorials public for everyone to DIY and learn from.
