Unicycle self-balancing robot produced by Zhihuijun

This little robot is called ONE, which is actually a work UP made when he was in school five years ago. After finishing it that year, I never had time to sort out the materials. During this period, many classmates came to ask me questions related to this project. This time, I simply uploaded the materials to Github and made them open source. Open source information includes the source code of the STM32 main control and the 3D model files of the mechanical structure. The circuit source files can no longer be found due to their age. Students with basic knowledge can study it by themselves~

Open source AutoQuad flight control based on i.MXRT1052

This is an original work by netizen jiezhi320 who participated in the RT-Thread application competition. In 2015, jiezhi320 made a version of hardware based on stm32f405rgt6. However, due to the high CPU usage of the UKF algorithm, the author migrated it to imx-rt1052, in order to leave enough resources for everyone to develop in-depth for model friends.

short-term weather forecast system

The author is located in an area with a lot of convective weather and hot and humid weather. I stared at it silently, and saw that the clothes to be dried came in and out five or six times a day... Weather forecast on the mobile app? Weather warning text message? It can only be regarded as a late report. I am lazy, do it myself, have enough food and clothing...

Image recognition intelligent tracking car source code based on TMS320F2812

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.

Automatic round trip car report based on Launch_pad (program + schematic + PCB)

The MSP430 microcontroller is used as the detection and control core of the car; a photoelectric sensor is used to detect the black belt on the road, and the feedback signal is sent to the MSP430 microcontroller, so that the MPS430 microcontroller controls the car to drive at a predetermined speed in each area according to the predetermined working mode, and The MSP430 microcontroller can control driving in different directions depending on the working mode selected; the Hall element A44E is used to detect the driving speed of the car; the 1602LCD is used to display the driving time of the car in real time. After the car stops driving, the driving time, driving distance and each speed zone of the car are displayed in turn. Travel time. This design has a simple structure and is relatively easy to implement, but it is highly intelligent and humane, and reflects intelligence to a certain extent.
