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.

Bluetooth smart lock solution based on MM32W wireless MCU series

Introducing a Bluetooth application solution with very rich usage scenarios - a Bluetooth smart lock solution developed based on the MM32W series.

UAV code and documentation based on STM32

The structural characteristic of a quadcopter is that it is equipped with a rotor on each of its four corners, which are driven by motors. The blades can rotate forward or reverse. In order to maintain the stable flight of the aircraft, the quadcopter is equipped with 3-directional gyroscopes and 3-axis acceleration sensors to form an inertial navigation module. It also uses an electronic controller to ensure its fast flight.
