The term endian is written by Jonathan Swift. This Book classifies all people into two categories based on the way they open the eggs. From the beginning, the people who open the eggs are classified as big endian, from the beginning, the person who

In practice, the value of some variables is limited to a limited range. For example, there are only seven days in a week, 12 months in a year, and six courses per week in a class. It is obviously inappropriate to describe these values as integer,

Printk Function We used the printk function in earlier chapters with the simplifying assumption that it works like printf. Now it's time to introduce some of the differences. In the previous chapter, we simply use printk as a printf function. It's

C language testing is an essential and effective way to recruit embedded system programmers. Over the years, I have both participated in and organized many such tests. During this process, I realized that these tests could provide a lot of useful
