Smart wearable devices based on RSL10

Through smart wearable devices, people can better perceive external and own information, process information more efficiently with the assistance of computers, networks and even other people, and achieve more seamless communication. In daily life, smart wearable devices are increasingly used and have more and more functions. The main functions include heart rate testing, blood oxygen concentration testing, CO2 concentration testing in the environment, and temperature and humidity testing. etc.
This work is a smart wearable device based on the RSL10 development board officially provided by EEWORLD. This device is divided into two parts: the host and the slave. However, this MCU only has one UART, but in actual project requirements we need to use two UARTs. The organizer of this event gave five boards, so a board without a sensor is used as the SPI slave and will receive The command parses and uses AT commands to control the audio.

This project gave me a deep understanding of the gap between domestic products and foreign products in terms of low power consumption. Most of the domestic low-power products are still at the uA level, basically between 0.1-0.3uA. , but foreign products have achieved the nA level. It has to be said that there is still a gap in low power consumption. Before I used ON Semiconductor's Bluetooth, I had never used an operating system like Kernrl, but through this project, I had a new understanding of the operating system called kernel, and it also gave me an understanding of this type of kernel scheduling system. scheduling mechanism. In addition, this project is also my first time to use a UI interface made by myself, which is also a big improvement for myself. As for DSP, the DSP environment is still in the process of being established. You can experience Bluetooth with DSP later.
