In high-speed PCB design, the requirements for EMI and EMC are very high. In the design, it is impossible for humans to perfectly solve EMC and EMI problems. We can only grasp some methods in the deta...
[size=5] When running the ZigBee sample program, I found that the version was too low. After installing 7.50, I found that it could not be used. I used 360 to uninstall and reinstall, but it still did...
I was drinking with a friend from Infineon, and he told me a joke about someone with a wry smile. Friend: I was arrested again today Me: What's the problem? Friend: It's not the induction cooker. The ...
From the PIC16F946 datasheet, we know that there are two ways to write values to the LCD for display:
1. Directly write the value to LCDDATA1~LCDDATA23
2. Use disconnect t...[Details]
1. What is temperature?
Heat is a type of molecular motion. The hotter an object is, the faster its molecules move. Absolute zero is defined as the temperature at which all molecular motion ...[Details]
LED lamps and bulbs are now rapidly replacing incandescent, halogen and CFL (compact fluorescent lamp) light sources in many general lighting applications. Flyback DC/DC converters are the power su...[Details]
