A revolving lantern based on RTX51tiny, a simple multi-task scheduling example... I've had some time to learn 51, and recently I fell in love with the small system RTX51tny that comes with the 51 micr...
I am working on a project that requires low power consumption. The chip is STM32L151C8T6. I found some posts online that say that the unused pins on the hardware can be left floating. STM32Cube can be...
During the National Day holiday, an epidemic broke out in Harbin, which was finally brought under control after strict prevention and control measures.
At that time, temporary checkpoints were set up ...

Bioelectric signals are very weak, and there is strong interference when detecting them. Therefore, there are many technical difficulties in designing high-quality bioelectric ampli...[Details]
With the development of automatic control technology, the application of precision air pressure generation and control technology is becoming more and more extensive. However, the traditional valve...[Details]
As a single-host multi-slave bus system, the number of slave devices that can be connected to a 1-Wire bus is almost unlimited. In order to avoid logical conflicts, the 1-Wire bus interfaces of all...[Details]
1 Introduction
In the current test field, the correlation detection method is increasingly widely used for filtering. Correlation filtering can easily separate a signal of a specific frequency...[Details]
