All information is fully open, and there is also a mobile APP, and the algorithm is also made public.
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.
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.
Introducing a Bluetooth case - a data transparent transmission application developed based on the MM32W series.
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 PicoCray project connects multiple Raspberry Pi Pico microcontroller modules into a parallel architecture, utilizing the I2C bus to communicate between nodes
The lazy self-care fish tank control system is mainly aimed at fish farming enthusiasts. As long as you use your mobile phone through BLE, you can manually control the start, stop, and feeding of the fish tank's electrical appliances. At the same time, the real-time time, supplementary lighting time, automatic feeding time, water temperature monitoring and alarm, etc. can be set through the APP at once. Enthusiasts are only responsible for watching and appreciating the fish, and the other things are left to the control system!
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.
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.
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.
A stator-side direct power control algorithm based on multi-frequency proportional integral resonant controller
A low-cost, non-contact DIY infrared thermometer based on ESP8266 can help people measure their temperature safely and prevent the spread of the new coronavirus.
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)
