As we all know, Win95 has the function of setting passwords, but I wonder if you have noticed that when returning to Win95 from the "suspend" state, the system does not require us to enter a password....
1. After creating TFFS, formatting FLASH and mounting it, I can see "/tffs" using the devs command in SHELL. I can execute LS and CD commands, but when I execute the copy command, it says that the sym...
I recently got an omap board and tried the basic stuff in it. But an error occurred during the reflash phase when re-burning uboot. Now uboot won't start. I don't have a jtag emulator, is there any ot...
I am a rookie who has just started working. I am engaged in power supply research and development. During this period, I read a lot of books and I don’t understand a lot of things. There is no one to ...
Often, we want to make a design, but it is difficult to buy chips because we need a small amount and we just want to play around with it or do some experimental experiments. Then you can apply for sam...
All electronic design engineers and scientists have performed electrical signal analysis, or signal analysis for short. Through this basic measurement, they can gain insight into signal details and...[Details]
Editor's note: In order to help technicians or engineers who have knowledge of PIC microcontroller assembly language quickly master the method of using C language to program PIC microcontrollers, t...[Details]
1. Introduction
At present, most lighting equipment still uses traditional energy for lighting. Making full use of solar energy as the energy supply for lighting equipment is of great si...[Details]

Overview:
This paper introduces a method of connecting a CAN-bus network with Ethernet to form a medium-sized remote monitoring/data transmission network.
CAN (Controller Area Network) is ...[Details]
Many battery-powered systems require a visual indicator to show when the battery needs to be replaced. LEDs are commonly used for this purpose, but they consume at least 10mA of current. This con...[Details]
1 Introduction to LED
With the development of science and technology, people have higher and higher requirements on automobile light sources. LED (Light Emitting Diode) has gradually attracted...[Details]
summary
This article will briefly analyze the success and shortcomings of high-frequency DC-DC switching power supplies in the process of miniaturization (the second basic goal), and propose m...[Details]
Don’t just look at the power when choosing a power supply
We know that a power supply with a low rated power can hardly meet the power supply needs of the system, which may cause frequent free...[Details]
The principles to be followed are as follows:
(1) In terms of component layout, related components should be placed as close as possible. For example, clock generators, crystal oscillat...[Details]
LonWorks fieldbus technology is widely used, for example, in intelligent buildings, industrial control, environmental protection, etc. Echelon's LonWorks system has been used in the products of tho...[Details]
Abstract: Based on the analysis of the characteristics of the IRIG-B (DC) code type, a design method for IRIG-B (DC) time code decoding is proposed. This method consists of a small number of periph...[Details]
Traditional synthesis techniques are increasingly unable to meet the needs of today's very large and complex FPGA designs implemented in 90nm and below process nodes. The problem is that traditio...[Details]
Some people think: as long as the program runs well, it doesn't matter how the original program is written. But this is absolutely not the case. Software is not completed in one go, and it is neces...[Details]
Traditionally, when using PLC to control stepper motors, a dedicated stepper motor control intelligent module is usually added to the PLC, and then connected to the drive power supply to realize th...[Details]
