Simple pedometer design based on GD32F350

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.

Bluetooth power amplifier board based on TPA3110

Using TPA3110 digital power amplifier chip, the power can reach 15W, and there are two power interfaces. The Bluetooth part uses bk8000L finished module, which has good performance and affordable price. Supports button playback and pause, track switching, volume adjustment, and also supports external audio line input and microphone input. After testing the finished product, the sound quality is good, the Bluetooth connection is relatively stable, the button functions are normal, the external audio line input is normal, and the microphone calls are normal. A complete AD project file is provided, which can be modified as needed, and the BOM needs to be exported by yourself.

Abdominal breathing training trainer

The design is based on the SensorTile.Box kit, which is set to expert mode for direction change detection (using a gyroscope), close to the practitioner's lower abdomen; the LIS25BA bone conduction sensor collects and identifies the vibration signal of the user's breathing status at the nostrils. The signal output is also connected to the central main control circuit. The optimal compliance judgment for monitoring the breathing process coordination during the entire exercise process and the corresponding voice prompt information broadcast are made by the central main control circuit.

EnDat 2.2 Absolute Encoder Master Interface Reference Design for C2000 MCUs

C2000 Position Manager technology provides a turnkey solution for connecting digital absolute encoders as well as resolvers and SINCOS sensors, eliminating the need for additional circuitry commonly found in industrial inverters and servo drives.
