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.
The very early model was a bit crude.
Mega-Cube is a light cube that drives 4096 LEDs based on PL9823. The main control is Teensy4.0 based on NXP i.MXRT1060 FlexIO function and many 595 shift registers. It can control up to 32 channels, each channel 1000 LED.
There are many I/O methods that simulate UART, SPI, and I2C protocols, but there are very few that simulate CAN protocols. The CANT introduced today is a CAN bus simulation implementation. The original project was demonstrated on the ST Micro Nucleo-H743ZI board. The author recently launched a C and Python package - canhack, which facilitates porting to various chips without CAN.
A design example of implementing a simple MP3 Player using an STM32 processor. This comprehensive application example helps readers understand the applications of STM32, SPI interface, SD card, TIMER, interrupts, FAT file system, USB, etc.
ESP32s2 Thermal Imager=ESP32s2 + Lepton 3.5 + Battery charger + 240x240 pixel LCD
This is a simple USB sniffer based on the Raspberry Pi RP2040. It supports low speed and full speed modes. The firmware presents itself as a virtual COM port (VCP), so no additional software is required and it is compatible with all operating systems.
It adopts Qinheng's self-developed RISC-V microprocessor "Highland Barley V4" and integrates 2Mbps low-power Bluetooth on the chip. It is equipped with a blood oxygen and heart rate module, a nine-axis sensor, a motor drive module, a low-power touch detection module and a 0.96-inch high-definition IPS display to meet the application needs of general bracelets.
SimplePnP is designed to be reliable, accurate, affordable, and adaptable to a wide range of components. It's a great choice for electronics startups, inventors, researchers, and hacker spaces.
All information is fully open, and there is also a mobile APP, and the algorithm is also made public.
ST25R3916 based NFC reader expansion board for STM32 and STM8 Nucleo
Protues simulation example (8051)-PWM wave output (adjustable)
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
This reference design demonstrates the use of IWR6843, which is a single-chip mmWave radar sensor with integrated DSP for an indoor and outdoor people counting application. This reference design uses the IWR6843ISK evaluation module (EVM) and integrates a complete radar processing chain onto the IWR6843 device. This solution can detect up to 250 objects, and point and track up to 20 people with a field of view (FOV) of ±60º in the azimuth (horizontal) plane.
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.
