SDRAM is still in use in the memory, although the subsequent DDR replaced, it is important to master it. Before debugging, it really cost a great effort, its complexity is undoubtedly, the general people want to understand him, it will take about 1 months, at least I think so. What is the role of SDRAM, anyway? The answer must be storage, if you do not use it in the project, it is difficult to appreciate the role of it, recently in the SDRAM VGA displ

resolution in the market has two main indicators: 1920x1080, 1366X768. For example, the physical resolution of 1366X768 indicates that its imaging device has 1366X768 pixels. At the same time, pixels are also the basic units of the image. A 1920x1080 resolution image indicates that the image consists of 1920x1080 pixels. Only when the resolution of an image or signal source is exactly the same as the physical resolution of the TV can their pixels be mapped one to one (point-to-point display ),

, there are different things to consider. One is to consider objects that follow interface rules, and the other is to consider instances of specific classes. The interface is more flexible, and the implementation function is also relatively simple. The specific class can implement the function and provide some additional information. For example, there are three PC output signal modes: VGA, DVI, and HDMI (and many other modes ). The company has a
