Experts: Please help! I developed a player in EVC using DirectShow. When playing WMV files, there is only sound but no video! In the WINCE OS design, the added features are also added! I don't know wh...
I used pb 5.0 a few months ago, and now I picked it up again. As a result, I found that the content under Workspace->FileView seems to have changed. There are three main items under the root directory...
Below is the circuit. The function I want is very simple. When the button is pressed for the first time, the last two digits of the digital tube display increase by 1, and then return to 100. Can this...
I have just come into contact with MSP430 microcontrollers. I just saw this code and it seems a bit strange. For example, P1DIR &= ~0x08; Why not just write P1DIR &= 0xF7; or directly P1DIR=0XF7; (wit...
I have done 51 and AVR microcontroller development work before, and I also have some knowledge of VC++. I want to learn ARM system development, but I don't know anything about LINUX. It seems difficul...
Can the ADC status register be cleared by software? The manual says it can be cleared by software, but when I was operating it, I found that it was not cleared. Both software and hardware simulation s...
