Sweeping the floor is just my superficial job. My real identity is a researcher. Computer circles are really amazing. They can explain mapping so well. I really admire them. Mapping is equivalent to r...
RT, I have been writing WinCE drivers for a while, but I am ashamed that I still don't understand the difference between kernel-mode drivers and user-mode drivers. I would like to ask for your advice....
I am using a 1PG positioning module to control the servo to return to the origin. When it reaches the DOG switch, the servo does not crawl to a stop but stops immediately, and the PGO signal light doe...
My graduation project is to display shell commands on both the LCD and the HyperTerminal of the experimental box. After I ported the kernel, if I use the file with QT, i.e. root-qtopia-china.cramfs-32...
I was very happy to receive a keyboard from the forum, but when I opened it, I was shocked to see that one corner was damaged. I was so sad that I couldn't even cry! :Cry:...
Hello everyone, I just started to use the STM32 development board. The main chip is stm32f103zet6.When doing spi communication, I use KEIL MDK to do single-step debugging. After executing the SPI_I2S_...
Today's computer peripherals are pursuing high speed and high versatility. In order to meet user needs, seven companies led by Intel launched the USB (Universal Serial Bus) bus protocol in 1994, wh...[Details]

There are three types of mobile TV: one is based on analog TV broadcasting network, another is based on mobile communication network, and the other is based on digital broadcasting network. The f...[Details]
In this article, the high-performance DSP developed by TI can be used as an effective confidentiality method if it is applied to PC encryption cards.
As an effective network security solution,...[Details]
The solidification and modularization of intelligent video analysis algorithms are the current trends in the application of intelligent video analysis technology. It perfectly combines intelligent ...[Details]
1 Introduction
Ultrasonic waves have strong directivity, slow energy consumption, and can propagate over long distances in a medium, so they are used for distance measurement. Ultrasonic detec...[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]
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]
Contact resistance
is the resistance to current flow through a closed pair of contacts. This type of measurement is performed on devices such as connectors,
relays
, and switches. The...[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]
Since the No. 4 blast furnace of Handan Iron and Steel was put into operation in 1993, its external equipment has been seriously aged, and the original PLC control system TDC3000 of the hot blast furn...[Details]
