My sate210 VGA has achieved a resolution of 1024*768 for a long time, But Bt's 800*600 is hard to find the appropriate parameters. I thought those parameters didn't move, it's just a matter of modifying the width and height. The result is very bad. Later, the team engineer wrote an LCD and VGA wince debugging assistant. After a few times, it was still difficult to debug. This morning, I got up and tried the

High-definition TVs are becoming more common at home, and these high-definition TVs mostly have VGA, DVI, HDMI interfaces. The laptop screen is too small, and most people in the office want an external monitor. So understand the difference between these three kinds of video signal interface, is the premise of choosing suitable display. 1, in advance, the following: Three kinds of connectors have a common needle and the difference between the female n

Today I did a VGA display experiment, but the 25 m clock is incorrect, so no image is generated. The initial program is as follows: The timing sequence is displayed during simulation, but it is incorrect when the hardware is downloaded. The result is correct. In addition, the results of edge-based triggering and level-based triggering for frequency division are different. The following is a VGA experimen
