Supports voltage, current, effective power, apparent power, power factor, frequency, and harmonic component display.
This Near Field Communication (NFC) reference design provides a firmware example for implementing an NFC reader/writer application using the TRF7970A NFC transceiver. This reference design provides a number of easy-to-use application programming interfaces (APIs) that allow users to quickly implement NFC reader/writer functionality. The accompanying documentation, hardware, and sample C code allow designers to develop NFC reader/writer applications using the ultra-low-power MSP430/MSP432 MCUs or easily port to other carefully selected MCUs.
This project includes all the software and hardware design required to develop the T12 soldering station. The PID parameters are mature and the function completion is very high.
Introducing a simple and highly scalable application solution - a data acquisition instrument developed based on the MM32W series.
"Bluetooth controlled car based on stm32f4" is a motor drive module, power management module, stm32f4 main control module, Bluetooth serial communication module, and android control module based on the STM32F4 DISCOVERY development board produced by STMicroelectronics and ARM. The motor drive module uses two L298N chips to drive 4 motors. The enable terminal is connected to 4 PWM wave signals from the main control board, and the 8 input terminals are connected to the 8 output ports of the main control board; the power management module uses LM2940 -5.0 chip converts 12V to 5V, 12V is used for power supply of motor modules, and 5V is used for power supply of Bluetooth modules, sensors, etc.; the main control module uses the MDK editing program and then downloads it to the main control board to realize the integration of hardware and software Interaction; the Bluetooth serial port communication module uses the FBT06_LPDB pin-in Bluetooth module to communicate with the main control board through the serial port and at the same time communicate with the android phone; the android control module is a set of functions such as turning on Bluetooth, searching for Bluetooth, and controlling the car. Users can control the movement of the car through the android control terminal to achieve some functions and services that users need.
The MPC8379E-RDB is a highly integrated reference design board based on the NXP MPC837x using Power Architecture® technology .
Open source material for the Arduino UNO Mini Limited Edition.

Supports various Cortex-M cores, can be used wirelessly in the local area network, and can be used remotely in the external network.
AT89C52 microcontroller is used as the core control component to design an electronic keyboard. The microcontroller is used as the main control core, and it forms the core main control module together with the keyboard speaker and other modules. The main control module is equipped with 8 buttons and a reset button.
A hardware control circuit with TMS320F28335 as the core was designed, and experiments were conducted on the AC speed regulation SVPWM algorithm.
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.

This little robot is called ONE, which is actually a work UP made when he was in school five years ago. After finishing it that year, I never had time to sort out the materials. During this period, many classmates came to ask me questions related to this project. This time, I simply uploaded the materials to Github and made them open source. Open source information includes the source code of the STM32 main control and the 3D model files of the mechanical structure. The circuit source files can no longer be found due to their age. Students with basic knowledge can study it by themselves~
The product design is open source and very cool and beautiful.
Amethyst is a classic home computer developed by Matt Sarnoff. It has an integrated keyboard, can generate sounds and images, uses the Forth programming language, has image and voice commands, a debugger and screen editing functions.
The Raspberry Pi microcontroller itself does not have an Ethernet MAC, but it can be easily implemented through the programmable IO of the Raspberry Pi. The programmable PIO of the Raspberry Pi microcontroller that costs 5 yuan a piece is indeed a miracle, with IO below 250MHz. Control everything.
