1 IntroductionMost non-FPGA type, high-density ICs (such as CPUs) have very specific requirements for decoupling capacitors. Since these devices are designed only to perform specific tasks, their powe...
Due to the limitation of internal resources, the software design of MCU has its own particularity. The program generally does not have complex algorithms and data structures, and the amount of code is...
I have a problem. I use LQI to calculate the distance, because I don't know how to get RSSI. When there are 4 reference nodes, sometimes there is data loss, but the positioning function is basically a...
I have a question. In theory, it is enough to add terminal resistors at the beginning and end of the transmission line. But in actual operation, why do we need to add two terminal resistors at the beg...
High efficiency and low standby power consumption are two major challenges in today's switching power supply design. Resonant topology or LLC topology is becoming increasingly popular because it ca...[Details]
Abstract: In order to generate a stable excitation signal, the design of a digital frequency synthesizer is implemented on FPGA using Verilog hardware language. The design includes accumulator, wav...[Details]

1 What is an LED floodlight?
LED downlights are also called spotlights, projection lamps, and spotlights. They are mainly used for architectural decorative lighting and commercial space lighti...[Details]
Every time I go home and walk up the stairs, I am always scared. The corridor lights are often broken, and no one changes the bulbs, or they are not smart enough and need to be operated manually. E...[Details]
The capacity of a battery depends on the amount of charge and discharge, in addition to some factors of the battery itself. Obviously, if the charge and discharge of the battery can be recorded all...[Details]
