Many people, when designing PCBs, directly send the PCB files to the PCB board factory for processing. The samples obtained from the Slitung factory, especially the engineers who use Protel, Altium De...
This is the power supply of the ultrasonic plastic welding machine. The original circuit uses a half-bridge driver composed of NPN power tubes. Now it uses IGBT to drive it. The input signal is a squa...
The following code
unsigned char c1 ;unsigned int i1 ;i1=0x12 34 5678;
i1=i116;
i1=i10x000000ff;
c1=i1;
I want to assign the values of 3 and 4 in the i1 variable to the variable c1.Excuse me, is there...
