This project uses STM32F103RET6 as the main control, and is modified based on ST's official CMSIS-DAP project to achieve offline and read-protected programming (because the project currently only has F103 series offline programming requirements, so only F103 programming is temporarily added. write algorithm).
mini-violin is an open source project for violin design, and the circuit schematic is quite simple. The ATtiny85 controls two LEDs and a piezo buzzer, in addition to a button to switch songs. What's particularly interesting is that the violin strings are connected to the analog inputs of the microcontroller so that they can be controlled by contacting conductive materials. Come play the violin.
The MicroByte is a tiny console capable of running games from the NES, GameBoy, GameBoy Color, Game Gear and Sega Master systems, with all components designed into this 78 x 17 x 40 mm package.
With voice recognition function, you can use voice to search for weather, as well as radio, temperature and humidity, calendar and other functions.
Watchy is a completely open source and customizable e-ink screen watch. It uses ESP32-PICO-D4 as the core, has WiFi and Bluetooth LE connectivity, and is compatible with Arduino, MicroPython and ESP-IDF. The 200x200 pixel resolution e-paper display is clearly visible in bright sunlight and has ultra-low power consumption.
This project is a completely open source smart watch based on the ESP32 WROOM module, with a very high degree of completion. In the project design, serial communication and charging are completely through the onboard micro USB interface, without any external interface board processing.
Arduino development, weather, clock, reading, network distribution and other functions
Open sourced by Bilibili up, DCDC-LDO secondary step-down power supply, tc1047 for cold-end compensation, built-in curve fitting calibration function, and supports 65W gallium nitride charger.
ESP-Drone can be connected and controlled through Wi-Fi network using mobile APP or game controller. Currently, it supports multiple modes such as self-stabilizing flight, fixed-altitude flight, and fixed-point flight. This solution has a simple hardware structure, clear code structure, supports function expansion, and can be used in STEAM education and other fields.

Design and implementation of solar power generation simulation system based on TMS320F28335
The system is an intelligent tracking device based on TMS320F2812, which has the function of intelligently locking targets and automatically tracking locked targets. CPLD is used to obtain image information collected by the camera, and TMS320F2812 is used to process the image information. Median filtering, corrosion and other algorithms are used to extract target information, and then the target coordinates are calculated. The car movement is controlled through the internal PWM module of the DSP, and the target coordinates are wirelessly sent to the handheld device. Remote control device to achieve real-time tracking of targets.
The AC excitation variable speed constant frequency wind power generation experimental system was developed using TI's TMS320F2812 to complete the maximum wind energy tracking control experiment.
A hardware control circuit with TMS320F28335 as the core was designed, and experiments were conducted on the AC speed regulation SVPWM algorithm.
A stator-side direct power control algorithm based on multi-frequency proportional integral resonant controller
This design uses LM3S811 as the processor of the lubricating oil dielectric constant detection device, designs the AD5933 impedance measurement circuit, extracts capacitive reactance information from the impedance data, and calculates the change in the lubricating oil dielectric constant based on the change in capacitance to achieve lubrication control. Test the dielectric constant of oil and record the data to find out the change pattern between lubricating oil quality and dielectric constant.
