TFTP Construction Method
After setting up: the Development Board is powered on, and the serial port terminal stays in uboot state by pressing any key to enter the uboot command mode:
Set and save the uboot IP address and gateway. You can use the TFTP Command to

Recently made a similar Windows drawing board applet, to share with you. The function and the interface all imitate with the drawing board which the Windows own, the interface like screenshot. The main functions are: hand-painted lines, simple graphics, text input, block drag and drop, repeat undo, Zoom, open the Save picture file, in addition to directly from the database or XML access to the picture, but

Isn't the program finished? Why do we have to go through the second part? after reading the second part, we can see that the second part of the code is better, and all the code in the second part is rewritten.The above is still not a good structure. I

In this section, we add a message board to the online bookstore so that readers can post a book. The message board usually uses paging display when displaying users' messages, because thousands or even tens of thousands of messages may be stored in the database. If it is displayed on a page, it will surely make users dizzy. More import

Abstraction of S3C2440 bare-board program design (no operating system)
In the embedded field, almost all Device Control and various Protocol control are in the same embedded CPU, which is very helpful to abstract the CPU core and device. If we can abstract the control of CPU cores and devices, there is no need to have a deep understanding of CPU when porting OS or developing drivers, you do not need to know
