This Bilibili small TV uses esp32 as the main control, lvgl GUI interface design, and is developed based on idf4.0 to support smartconfig or WeChat airkiss distribution. Its functions include: network connection display, network acquisition time, weather display, temperature and humidity collection, Fan count display, mqtt temperature and humidity upload, etc. All software and hardware are open source.
This project started with STM32F1 and now it uses STM32F3.
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.
STM32F072 Type-C Port Manager Evaluation Board with ON Semiconductor FUSB307B Type-C Port Controller
Based on ESP32 and ATtiny861 to build a Nintendo NES game emulator handheld console with complete materials for making the project
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.
The GD32F350 development board uses the latest ARM Cortex-M4 32-bit general-purpose microcontroller GD32F350RB launched by GigaDevice. This chip comes with a 2-way comparator and is very suitable for making a low-cost digital capacitance meter.
TIDA-00721 is a complete reference design that enables accurate temperature measurement using passive NFC tags in a flexible patch format. The system provides temperature readings via an NFC receiver (such as an NFC-enabled smartphone) tag. A high-precision temperature sensor (LMT70) is interfaced with an ADC (ADS1113), and the temperature data is sent to the reader using an NFC transponder (RF430CL330H).
STM32 Nucleo-64 development board using STM32G070RB MCU, supporting Arduino and ST morpho connections
This design is based on the design and development of the Modbus_RTU (RS485) bus Remote Inputs/Outputs Modules system of GD32E231.
This article designs to use GD32E231 to collect environmental data such as temperature, humidity, and infrared detection, and then transmit the data to the backend system through wireless transmission. This design uses GD32E231C8T6 to control the temperature and humidity sensor DHT11, human body infrared detection module, OLED and LoRa communication module, etc. The adopted temperature, humidity and infrared alarm signals are displayed through OLED, and the data is transmitted to the LoRa node in the background through the LoRa communication node, and finally uploaded to the host computer.
This intelligent atmospheric environment and corrosive monitoring platform integrates hardware, software, and network. With the stable performance IACM-321 platform system as the core, it realizes multi-level dynamic networking and remote status monitoring. It can be monitored in the monitoring/operation and maintenance center. The front-end system provides centralized monitoring and unified management, and uses customized intelligent terminals to achieve mobile monitoring. Convenient Click connect sensor interface, easy to install on smart terminals.
Based on STM8S003K3 microcontroller, it has alarm and chime functions and automatic light sensing function.
