Tear: Install linux6.0 -- Linux general technology-Linux technology and application information. The following is a detailed description. [I = s] This post was last edited by the empty sky at, September 17 ,.
When the red flag linux6.0 was installed on the CD, the system prompts that the hard disk could not be found. After a day, I checked the reason on the Internet. Some said that the hard disk could not be recognized by linux6.0, some say that the configuration is changed to the compatibili

Recently, I am working on a capacitive touch screen driver and using I2C bus interfaces to transmit data. So let's take a look at the I2C bus principles.
The I2C bus is a character transmission bus between chips launched by Philips. It adopts two-wire system, which consists of the serial clock line SCL and serial data line SDA. In the circuit design, the I2C bus interface is open or open collector output, and the pull-up resistance is required.

Note: Some users may need the superuser permission to use ADB. In this case, the home directory in step 1 should be/root. If you don't want to bother, add both home directories directly.

It seems that there are still a lot of people who use ATI graphics cards. It is a pity that a classic video card like 8500 cannot run 3D games under X.
!! Note 1: This article only applies to 8500 and above graphics cards. ATI does not officially mention support for radeon/7000/7200/7500.
!! NOTE 2: redhat9 has good 2D support for ATI graphics cards and supports 3D acceleration to a certain extent, if you do not belong to (1. You can enter X but need good 3D acceleration and have enough DIY spir
or more additional device IDs, because multiple devices are compatible with the device recognized by the initial hardware ID and are also driven by the same driver. When the device manager finds the ID defined by this segment, the Device Manager will find the correct inf file.The example specifies a device. The vid of the device is 0x045e, And the PID is 0x930a. The VID is allocated by the USB Management Board to each USB chip manufacturer. For example, the vid of

a low-speed serial bus protocol used in micro-control applications promoted by Philips. This option is required if you want to select the following video for Linux.
Mice: Mouse. Now you can select bus, serial port, PS/2, C T 82c710 mouse port, and pc110 digitizer pad as needed.
Joysticks: handle. Even if you drive the handle in Linux, it doesn't make much sense, and there are too few games.

Simulation of I2C bus multi-master communication research and Software Design
Author:■ Zheng Xuyang, Xi'an University of electronic science and technology, Li Bingbing, Huang Xinping
Abstract:This paper introduces the principle of multi-master communication simulating I2C bus, and proposes a new implementation method. This method uses delayed receiving comparison to implement arbitration, so that common Microcontroller (MCU) without I2C interfaces can implement multi-master communication that si
