In embedded software development, it is common to see friends defining custom protocols, mainly due to resource constraints and the relatively specialized functionality. Subsequent maintenance is also much simpler. However, at a certain stage or scale of the project, one must consider issues such as scalability and compatibility, leading to a variety of protocol designs. … Read more
A case study of a minimalist wooden style single apartment with a construction area of 60 square meters. The space is relatively compact, and the designer has implemented some embedded storage designs that combine appliances and cabinets, making this home more convenient to use. Without further ado, let’s take a look at the renovation effect … Read more
1. Detailed Explanation of I2C Communication Principles 1. Hardware Structure and Physical Layer Bus Topology: The I2C bus is a multi-master/slave structure that supports multiple master and slave devices sharing the bus. SCL (Clock Line) and SDA (Data Line) are both open-drain outputs and require external pull-up resistors (typical value: 4.7kΩ, specific values should be … Read more
In recent years, the Binhe Street has closely focused on the modernization goals of grassroots social governance, deeply implementing the central government’s deployment of community embedded service construction as a livelihood project, and concentrating on the task requirements of creating a convenient and comfortable “good community”, a well-serviced “good neighborhood”, and higher quality “good housing” … Read more
