The system uses TI's MSP430F149 microcontroller as the core controller. This microcontroller has a 16-bit CPU integrated register and constant generator, which can maximize the code efficiency of the microcontroller. It integrates JTAG and supports online programming; two universal full-duplex Serial synchronous/asynchronous communication interface; PWM control output; external interrupt input interface. The microcontroller is responsible for sampling the bus door opening and closing signals, turning on or off the infrared counting module, recording the number of people getting on and off at each bus stop, storing the data on the number of people getting on and off at each bus stop, and transmitting the stored data to the computer.

MCIMX8M-EVK is an evaluation kit for i.MX 8MQuad, which provides high performance with high-speed interface and audio and video functions.
This application note describes the use of a current-sense amplifier along with an optocoupler to extend the operating voltage range up to 1,000 volts for high-voltage applications. The circuit relies on the optocoupler's isolation barrier to separate the high-side and grounded side of the 1,000V system. Op amps are used to eliminate photodiode non-linearity and drift and provide an accurate output voltage proportional to the load on the 1kV supply.
It is the first open source system to achieve 70+ mAP (75 mAP) on the COCO dataset and 80+ mAP (82.1 mAP) on the MPII dataset. To match poses corresponding to the same person in frames, an efficient online pose tracker called Pose Flow is also provided. It is the first open source online pose tracker to achieve 60+ mAP (66.5 mAP) and 50+ MOTA (58.3 MOTA) on the PoseTrack Challenge dataset. AlphaPose supports Linux and Windows.

Grapevines use a lot of water and the soil dries out quickly, so they need to be watered twice a day. This project is about using an unmanned watering system to water flower pots.
Use an idle Android phone to place it on a drone or unmanned vehicle/boat to realize wifi, 4G, 5G remote control of the drone, image transmission/data transmission/remote control integration. Supports APM and Pixhawk flight control (as long as it is compatible with Mavlink protocol), supports RTK differential GPS high-precision positioning (optional function, requires ublox NEO-M8P GPS module and Qianxun FindCM service account).
The STM32 Nucleo-64 board provides an affordable and flexible way for users to try out new concepts and build prototypes by choosing from the various combinations of performance and power consumption features, provided by the STM32 microcontroller.
The 4K Ultra HD display reference design enables emerging applications of DLP Cinema® technology such as digital signage, laser TVs, and office or education projectors that require cost-effective high-resolution solutions for large, bright digital displays. Comes proven and reliable performance. Delivering twice as many pixels as competing products, DLP micromirror technology's advanced image processing and high-speed switching capabilities enable 8.3 million pixels of resolution on the screen, delivering clear and detailed images for any scene. Whether a stand-alone display system or embedded into an existing design, complete reference designs and development guides accelerate display product innovation.
