This computing watch is designed using the SAML22 ARM microcontroller. This particular microcontroller has a segmented LCD controller capable of driving the LCD used inside the watch.
The PicoCray project connects multiple Raspberry Pi Pico microcontroller modules into a parallel architecture, utilizing the I2C bus to communicate between nodes
Introducing a Bluetooth case - a data transparent transmission application developed based on the MM32W series.
This ESP32-based FPV car can stream video over Wi-Fi and only needs a small LiPo battery for power. It can be controlled remotely and accurately through any web browser.
A simple oscilloscope made of STC8A8K MCU. The microcontroller uses STC8A8K64S4A12 working at 27MHz. The display uses a 0.96 OLED with a resolution of 128x64. This oscilloscope project is easy to start and covers the necessary measurement functions. Supports normal mode, single mode, and automatic mode. It has trigger mode selection, such as level trigger, and comes with saved settings. Mini-DSO input is single-channel mode, and the second/division size can support a variety of: 500ms, 200ms, 100ms, 50ms, 20ms, 10ms, 5ms, 2ms, 1ms, 500us, 200us, 100us, and the voltage acquisition range is 0 to 30V. The sampling rate can reach 250kHz@100us/div.
ST has previously launched a board with a static current measurement range of 1nA - 100mA and a dynamic current measurement range of 100nA - 50mA, but it is not open source. This time it’s open source.
The WiFi remote control is based on ESP32 Pico D4 MCU and 160x80 pixel mini TFT display. Additionally, there are onboard I2C temperature and humidity sensors and an accelerometer.
You can record your life anytime and anywhere, remember people's names, calculate food calories, translate in real time, and have intelligent conversations...
A stator-side direct power control algorithm based on multi-frequency proportional integral resonant controller
Not only is it open source, the author also has a super-detailed record of the design process. The bandwidth of each analog channel is not reduced in order to reduce costs. Each channel has a bandwidth of 350MHz, and higher sampling rate support can be designed in the future. Thunderbolt USB4 interface, speed up to 1GB/s (8Gbps)
HT-Hawk is an open source flight control system suitable for multi-rotor aircraft. It supports four- and six-rotor aircraft. It is an open source autopilot system developed for multi-rotor aircraft enthusiasts. It can achieve attitude stabilization and provide users with excellent performance. Flight experience.
These demos all use Adafruit's PicoDVI branch, which makes the video framebuffer look like a regular Adafruit_GFX object, which makes drawing very easy.
The Power Profiler Kit II (PPK2) is a stand-alone unit that, in addition to external hardware, can measure and optionally source current on all Nordic DK boards from sub-uA up to 1A.
This article designs a vending machine based on the 80C51 microcontroller produced by INTEL.
The Pandora McNado smart car based on Rt-Thread is composed of chassis, drive, battery, Bluetooth, APP control, omnidirectional wheels, etc.
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).
