With the Ucos test box, now transplanted Ucos+ucgui, the transplant process can refer to my previous article, I give a project example.In this project I have set up four tasks:Task one: Collect analog signals from the outside and save them to the cache, and try to display them on the screen.Task two: The display of desktop controls and the handling of controls.Task three: The external resources of the ARM processor,
The exhaustive screen map from the previous lesson isn't tied to a participant device form factor, although it can generally look and work okay on a handset or similar-size device. but Android applications need to adapt to a number of different types of devices, from 3 "handsets to 10" tablets to 42 "TVs. in this lesson we recommend e reasons and tactics for grouping together multiple screens from the exhau

I used Zhou ligong's test box. Now I have transplanted UCOS + ucgui. For the porting process, refer to the previous article. Below I will provide a project example.In this project, I have created four tasks:Task 1: Collect analog signals from outside and save them to the cache. Try to display them on the screen.Task 2: Display and processing of the desktop control.Task 3: External Resources of arm processors, including digital tubes
Recently engaged in the development of industrial touch screen computer system, the system installed is a streamlined WinXP system. Given that the system is streamlined, there are some features that might not be available if you use WinForm technology directly, not to mention WPF. and the traditional C/s development deployment, modification is a problem, so in the B/s development can be competent, the prefe
Android uses a touch to dynamically draw a rectangle and an android rectangle on the screen.Requirement Overview:
Draw an area with your finger on the screen and return the coordinates of the area in the circle.Technical implementation:
Customize the View, set the paint brush and corresponding parameters, and judge the touch event in the onTouchEvent () callback
HDMI. As for the screen, the 1366*768 resolution is lower, but the screen itself is small, the perspective is good enough, it seems acceptable. Because of the support of touch operation, the screen coating on the side will have some reflective effect, but also helpless.

AndroidThe question of the difference between a real machine and a simulator is an eternal topic. Why can't you finish. The existence of a simulator plays a role in it, but do not trust it in everything. Unless you are an android pure upper-layer application developer or enthusiast, I suggest you discard the simulator. Its idealized guidance makes us a lot of trouble. Of course, this is also a good thing. At the very least, I was more interested in finding answers.
The reason for the problem is
happy. As for touch screen or mouse events, just call the appropriate ADB instructions. But a little bit of a problem is that the reaction speed is very slow, especially when the continuous simulation of multiple keys, even the crash.While the key wizard runs quite smoothly, I began to wonder how the key Wizard was implemented. And then finally found the reason, when the simulation button, should not be ca

My CPU is around MHz, which is equivalent to the S3C2440 level. When I start the first program-qws, it takes about 3 s to run books-qws and 6 s to run browser-qws, other large programs will exceed 10 s. I feel that the speed is not fast enough. In addition, the memory consu
Today, we have to introduce a touch screen effect, we used to browse the site details page, often see such an effect, when you click on a picture, you will be the other pictures in the window mode display, and then, you can go up and down the button to achieve the picture switch.
So, how do you do that on your phone?
I lined up a group of small graphs, and when I clicked, I put the picture in the ID I

After two days of hard work, the screen saver test program was finally completed. Because it was necessary to be used in the project, we did a test first and hoped to be useful to everyone, I have not found any complete information on the Internet at the beginning, and I have no source code. So I have attached the source code today. I hope you can share it with me. The source code is http://download.csdn.net/detail/weijing331/4518413.
