I am a beginner in MCU. I have read many practices, but I still feel that they are not ideal. Because the processing requirements of the main task are very high.I really feel sorry for the precious re...
As an energy conversion device working in the switching state, the voltage and current change rate of the switching power supply is very high, and the interference intensity generated is relatively la...
I am a beginner and wrote a code, but when I run it, it prompts 0 errors and 3 warnings, and the light does not work properly. The code is as follows: #include
sbit D2=P2^0; unsigned int a; void mian(...
Record the small mistakes I encountered when I first learned FPGA:
1 You can use quartus to open the qsf file and modify it. Do not write anything in the unused area. Save and close it and compile it....
Why do I get the following two errors when calling the GetWindowsDirectory() function under EVC: G:\VCproject\Test00\Test00Dlg.cpp(67) : error C2039: 'GetCurrentDirectory' : is not a member of '`globa...

For the voltage regulator modules (VRMs) that power the latest computer central processing units (CPUs), power supply designers have historically used multiphase interleaved b...[Details]
Introduction
Power subsystems are becoming more and more integrated into the overall system. Power systems have moved from being separate "essential dangerous devices" to being monitorable...[Details]
Battery life is critical for portable applications. For applications such as smoke detectors, security devices, and thermostats, factory-installed batteries need to last for more than 10 years. The...[Details]
1. Disadvantages of choosing too high a voltage level
Choosing too high a voltage level will result in too high an investment and a long payback period. As the voltage level increases, the...[Details]
Today, with energy becoming increasingly scarce, the utilization of natural energy has become the focus of people's attention. Among various natural energies, the endless solar energy is highly fav...[Details]
