EmbeddedLinux arm Compilation (vii)--C language and arm Assembly mixed programming in the development of embedded system, the main programming language currently used is C and assembly. In large-scale embedded software, such as the OS, most of the code is written in C, mainly because C language structure is better, eas

Unix/linux Shell Programming Combat: Using embedded documents here documents First, here documents (embedded documents)Here, documents. As a way of redirecting, instructs the shell to start reading the output at the current location of the source file until it encounters a text row that contains only one word. All lines of text that are read in this procedure ar

--Embedded SQL programming --SQL2005 Administrator Daquan -An application that embeds an SQL statement is called a host program, and the language in which the program is written is called the host language. Host language can be C, C + +, Java, and so on. Embedded SQL statements are syntactically similar to interactive SQL --but

qualifier "I" preceding it from the input entry in the above code tells Gcc,cirqfiq that it is a constant. GCC is determined by the size of this constant to allocate it in registers (the registers are essentially the same as memory , the difference is in the very fast access and possibly the agreed storage) or directly in the instruction encoding data (to meet the conditions of the immediate number of storage). And before the instructions in __asm__ __volatile__ () are executed, generate the re

bit operation is another typical application in embedded system programming, in addition, it is widely used in scenarios such as bitwise AND (), or (|), non (~) Operation, which is closely related to the programming features of embedded systems. We usually need to set the bit of the hardware register. For example, we

operations on specific data. The class contains two categories: Data and operations. In C language, struct is only a collection of data. We can use a function pointer to simulate struct as a "class" that contains data and operations ". The following C program simulates the simplest "class ": # Ifndef c_class# Define c_class struct# EndifC_class{C_class A * a_this;/* This pointer */Void (* Foo) (c_class A * a_this);/* behavior: function pointer */Int A;/* Data */Int B;}; We can us
