[backcolor=rgb(239, 245, 249)][size=14px]This is the internal circuit of an LED bulb I copied. I don't quite understand it. The output voltage of the bridge stack should be 310V. Why is such a small c...
What are the pull-up and pull-down capabilities of a 0-10V dimmer? I want to connect 100 dimmer power supplies in parallel. Will the dimmer's driving capacity be insufficient?...
1: When laying out the board, first shrink the wiring area, hold down the right button, and see if the drawing board can be moved up, down, left, and right. If not, move it in the opposite direction u...

1 The significance of using RTOS on MSP430
It is understandable that it is meaningless to use RTOS on MSP430. Because the hardware resources of MSP430 are limited (for exampl...[Details]
Google's driverless technology is not only an eye-catching technology, but also a subversion of the car usage model.

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]
I. Introduction
In the field of power conversion, isolated converters (forward, flyback, and double-ended) with low output DC voltage all use MOSFET as the rectifier device. Since these devi...[Details]
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]
5. Identifiers and keywords of C language
A complete PIC microcontroller C language program usually consists of six parts: include files (i.e. header files 1, variable definitions, variable de...[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]
