I have never studied USB before, but now I need to build a USB system. It is roughly like this: we used Lingyang's SPCE061A development board to make a simple item manager. Now we want to add a USB in...
1 System Overview
As shown in the figure, this is the principle block diagram of the entire video acquisition system. At the beginning of power-on, the FPGA needs to initialize the register configurat...
Does anyone know how to sense a circuit 10 meters or more away? (That is, how to sense the voltage returned by the object or person in front of it) Can anyone tell me? I hope we can communicate with e...
I'm learning CC2530F256 recently. Now I'm debugging RF communication (simple RF communication, no protocol stack). Considering that there will be data collision during multi-point communication, how t...
Now there is a sinusoidal voltage with a peak-to-peak value of 1 to 1.5V. Can the peak value be detected using the following diagram? If not, is there any better method? Thank you very much! ! ! In ad...
I recently found a clever part when I was looking at the code. When you usually use 12864 or 1602 to display numbers, I believe everyone will first split it up, convert it into the corresponding ASCII...
Assume that data is read from 8-bit AD (if it is a higher-bit AD, the data type can be defined as int), the subroutine is get_ad();
