I have only learned some things about single-chip microcomputers before. Recently, I want to make a PWM waveform output and learn about DSP. Can you recommend some videos or books? I heard that DSPc20...
I would like to ask you guys how to quickly write the output logic expression for a logic circuit containing CMOS. I know there is a "serial or parallel", but if the circuit is more complicated, I can...
Dear friends, I am making a peak current sampling module recently. The peak value is maintained by capacitors. It is confirmed that it is a CBB (polyester) series capacitor, but it is not sure whether...
USB RNDIS enables the use of TCP/IP on USB, but this makes CE have an extra IP, which is equivalent to two network cards. When using gethostbyname() to return the IP list, sometimes the first one in t...
