Unveiling I2C Pull-Up Resistor Value Techniques: 5 Key Design Points and Practical Cases Introduction: Why Must I2C Be Equipped with Pull-Up Resistors? In the communication between the main control chip and other modules (such as cameras, sensors, etc.) in embedded systems, the I2C bus is widely used due to its simplicity, reliability, and low cost. … Read more
In PCB design, engineers need to follow a series of principles for layout and routing to create excellent boards. While some principles can be disregarded, there are certain principles that must be adhered to for the stability and safety of the entire system. So, what are the principles that all engineers must follow? 1. Reasonable … Read more
Source: Content from Embedded Information Selection, thank you! 1 Basic Principles of Hardware Design (1) Speed and Area Balance and Trade-off Principle: If a design has a large timing margin and can run at a frequency much higher than the design requirements, it can reduce the overall chip area consumption through module reuse, which is … Read more
Source: Internet After reviewing various embedded books available in the market, including MCS-51, AVR, ARM, etc., I found that none specifically introduce design principles, and even if there are, they are quite rare.Writing code is not difficult, but writing good and efficient code requires some experience.The idea of structured and modular program design is the … Read more
