name. After successful matching, the offset of the file in SD is obtained. The 9-bit offset (512 bytes, one sector) is the position of the file. Fopen returns a handle that corresponds to a data structure. The structure generally includes the start position, length, and current read pointer position of the file. The record start position and length are used to prevent cross-border reading.

Graphic software design for Binary Functions
This software is designed to create black-and-white illustrations for papers or textbooks. It uses gridlines to represent the 2-element function z = f (x, y). [Note: Actually, it is y = f (x, z), x, z is the independent variable. In this example, the funct

We started using our own network card, found that it is not possible, because the tablet's Android system does not support the driver download and installation features. After discussing with the classmates we contacted the teacher, received the factory sent the original network card, from then can use WiFi.V.

Single Responsibility principle: there should be only one reason for a class to change (ASD).
I just learned to program, is to learn the C language introduction. C language is a process-oriented language, just beginning to get used to, to now write the program will also be oriented process thinking impact. When it comes to object-oriented programming (Java), it's natural to add a variety of functions to a class, and then write all kinds of code in a class. But the disadvantage of doing so is tha
How to better design the software architecture is an eternal key topic in the software engineering field. Over the past few decades, the international software engineering community has made great strides in Software Architecture Design
The entire software development process is a rather complex process. Instead of simply writing software on the other side by a few design engineers, we need to start from the beginning to the end, including many people and different experts, different specialties and different knowledge are combined to form a complete softwar
The input signal of the access control system includes:
Landing Lever position sensor: Two position value signal (up/down)
Car entry sensor: Two values (True/false)
Car Gate sensor: Two values (True/false)
The output signal of the access control system includes:
Motor control signal for landing lever: (Up/down)
Traffic light signal: (Red/green)
The passing process of a car is:
The landing lever is in the falling state and the traffic light is red.

Software design method (reproduced)
In order to solve a problem on the platform, the last basic discovery can be implemented after a long time.
During migration to the project, we found that there was an issue that could not be solved by the platform. The problem has not been solved for a long time, and it is even unclear where the problem exists.
At last, my colleagues analyzed the problem step by st

What is architecture
Software designers who have high technical skills and rich experience need to design the architecture of the software system, that is to say, we need to design how the system's components are divided, how components interact, and how logical, physical, and important decisions are made in the system
