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.
Mainly using GD32F350 to make a light source controller to provide stable light source control for machine vision cameras, adding an external trigger function that can be connected to an external 24V signal (photoelectric sensor or PLC input), and a 24V output signal to trigger the camera to take pictures. Due to the diversity of application scenarios here, it is necessary to add user process configuration to control how long and when the four light sources are turned on respectively. Due to the life of the light source and the general glare of the light source, a parameter power-off retention function is added. In addition, it is also extended WIFI function. Live application scenarios are also tested in the video.
This work is a simple pedometer design. It mainly uses MEMS sensors to detect changes in human body posture. It uses a pedometer algorithm to implement a simple pedometer function. It uses an OLED screen as a display device and adds a GY-30 light sensor module to detect changes in brightness of the surrounding environment. To adjust the OLED backlight brightness in real time; at the same time, the on-chip RTC is used to realize the real-time clock function. Due to limited time resources, it can be expanded later to add heart rate detection, temperature, humidity and air pressure, voice playback and networking functions.
This design only implements the establishment of the basic framework, such as protocols, business processing, task processing, upper and lower computer interaction data, etc., and abstracts interfaces one by one, and calculates the solar altitude angle and azimuth angle at this time through SPA. Simply use the obtained azimuth angle, altitude angle, etc. to convert the PWM duty cycle to control the corresponding rotation of the servo. There is actually a lot that needs to be done.
A single-lead ECG acquisition system based on GD32F350 is designed. The system uses a single-lead method to obtain ECG signals. Users only need to install the lead electrodes on their hands, and they can check their ECG anytime and anywhere without going to the hospital to specifically check their heart health.

With the in-depth research of ultrasonic levitation technology by domestic and foreign scholars, ultrasonic levitation devices have developed from expensive horns and other equipment to structures composed of general-purpose commercial ultrasonic transducers. Combined with 3D model printing technology, any scientific researcher and Electronics enthusiasts can use these components to make ultrasonic levitation devices to facilitate related acoustic research. This technology was published in AIP Publishing by Asier Marzo et al. Based on its model, this design changes the main control MCU, uses the timer inside the MCU to generate accurate PWM waves, and improves the software so that the ultrasonic device can move the suspension stably during the axial suspension movement.

High cell count battery (>15s) systems are increasingly used in industrial applications. These applications are more cost-sensitive and require a simple solution that can include monitoring, protection and control functions, and even SOC (state of charge) information, rather than just basic independent hardware protection. This reference design provides the platform for a complete battery pack side solution. Contains all independent hardware protection functions of the bq76930, and implements a reliable communication interface for the host device to read battery information.
The PMP20172 reference design delivers up to 36W on two USB Type-C outputs. Input is 17VDC bus. These two outputs enable port power management. If only one port is used, the entire 36W will be allocated to that port. If two ports are used, 18W will be allocated on each port. Supported output voltages are 5V, 9V or 15V.
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).
The TIDA-00913 reference design implements a 48V/10A three-phase GaN inverter with precision shunt-based in-line phase current sensing for precise control of precision drives such as servo drives. One of the biggest challenges with shunt-based in-line phase current sensing is the high common-mode voltage transients during PWM switching. The INA240 bidirectional current sense amplifier uses enhanced PWM rejection to overcome this problem. This reference design provides an output voltage from 0 to 3.3V, regulated to ±16.5A, with a mid voltage of 1.65V, enabling highly accurate phase current over temperature. TIDA-00913 provides a TI BoosterPack-compatible interface to connect to the C2000 MCU LaunchPad™ development kit for easy performance evaluation.
