Wide bandgap semiconductor materials represented by silicon carbide and gallium nitride have the characteristics of high thermal conductivity, high breakdown field strength, high saturated electron dr...
There is an error when the out terminals of multiple FPGA components are connected to the same I/O port. Is this not possible? In fact, the out output timings of those components are different, so the...
I used directshow to write an MP3 player software and it is now playing normally. However, I tried to set the channel. I used IBASICAUDIO's PUT_BLANCE to set it, but it seems that it was only set in t...
To measure the settlement of a building, 17 monitoring points are set up on the building, and the settlement of each monitoring point is displayed by computer at the on-site monitoring center.Now we n...
