By learning Android Deep Exploration (Vol. 1) HAL and Driver development in the fifth chapter to build the test environment of s3c6410 Development Board, I have mastered the method of building the test environment of s3c6410 Development Board1 Installing the Serial debugging tool: MinicomIn Ubuntu Linux, for example, you need to install, configure, and debug minicom as follows:First step: Detect whether the current system supports USB to serial port#lsmod | grep usbserial If there are usbserial
S3C6410 is a low power, cost-effective RISC processor from Samsung, which is based on the ARM11 core and can be used in mobile phones and general processing applications. Since only a piece of s3c6410 ARM11 processor chip can not test the driver, therefore, the processor must also be based on some of the expansion of the column, such as the appropriate interface, so that can be debugged with the PC link. There are many development boards based on the s3c6410 ARM11 processor. This book uses the I

I. Lab tasks
1. Exercise 1
Part1: Compile the Assembly source program:
Assume Cs: Code
Code segment
MoV ah, 2
MoV DL, 3
Add DL, 30 h
Int 21 h
MoV ah, 2
MoV DL, 6
Add DL, 30 h
Int 21 h
MoV ah, 4ch
Int 21 h
Code ends
End
PS: I am familiar with MASM, so I used this compiler.
When the call was made, the ends was accidentally converted into an end, and an error was returned. The compilation was successful only after the change.
Part2: compile, connect, run, and debug the source program t1.asm.

In this way, the script file runs normally. However, some files cannot be found during compilation. This is because the path in the path file read by the xdc tool is not set

I prefer reading e-books, which is convenient. There are a lot of professional PDF books in my computer. It would be great if I could read e-books. If I went to a bookstore to buy paper books, I always felt inconvenient, we have to carry a book that is so thick; and our professional books are all foreign books with big heads. One book requires 70 or 80 RMB, and I am always reluctant to buy it. I also seldom buy books. I don't know why. I am always excited to buy devices that read e-books. (That'
Thin P is used as MP4 by LP to watch American dramas.I also wanted to write a WiFi hotspot detection software on thin p, and develop and implement the function of cracking wireless routers. Now I have to put it on hold.
Fortunately, LP conscience discovered that it had approved the ndsl purchase license.Although ndsl screens are not as good as PSP, the touch function is quite interesting, and it is not afraid to be used as MP4. HahaNdsl also has Wifi
INTRODUCTION
The following example is a simple program to read a file and print the contents to a standard printer. It gets the filename of the file to print from the DOS command prompt input line. The prompt input information is passed to the "program" in a buffer area of the "program Segment Prefix (PSP). The address of the "program Segment Prefix are passed to the" in the "ES and DS registers when the" program execution s Tarts. This is the progra
. Therefore, we need to render it to a texture and save it.1) render SpriteFrame into a texture
Since the rendering method in cocos3.x has been. the method in Version x is different (use the rendering command instead of 2. directly rendering in Version x), so pay attention to the following when generating the texture:
Sprite* pSp = Sprite::createWithSpriteFrame(pSpriteFrame /*one sprite frame*/);RenderTexture* texture = RenderTexture::create(
Neuros OSD is a digital video recorder that can automatically encode analog videos and DVDs as digital signals and store them or play them on TV.It does not carry memory, but can store programs to SD/MS/MMC/CF flash cards or mobile hard drives connected through USB interfaces.Based on the Linux system, firmware is fully open-source and has a wide application space.It can be used to record programs of different resolutions based on playback devices (such as P
few engineers have the experience or time to make all the necessary details, therefore, engineering teams generally only follow informal team building methods and team work processes. This is a waste of time, and the effect is not good.
If there is a defined process and a plan based on this process, the efficiency of engineers will be improved. Without such a process, they will stop at every step and think about what to do next and how to do it. Most engineering processes are complex and invo
