The printing method known as digital printing has come a long way since it was invented in Germany in the 18th century. Today, digital printing can print text and images on a variety of surfaces, incl...
I did a small experiment with PIC16F676 and wrote a small program. It runs fine on the board, but it fails to simulate on Proteus7.7. There is no response at all. I don't know why?Program function: Co...
I made a power supply with MC34063A, input 12v, output 5v. Normal working current 200MA, maximum current 700MA. The inductor used is 220uH inductor. The rated current of the inductor is 2A. I also pai...
I am working on an I/O card driver for vxWorks. Since it is my first time to work on a driver, I wrote a test program to test whether the card can be detected and work properly. The program's function...
[size=4]The reasons for the failure of chip inductors are mainly manifested in five aspects, namely, failure caused by solder resistance, solderability, poor soldering, open circuit on the machine, ma...
