vcds can bus

After the Linux pc/phone started, Dbus-daemo started. This is if a program is started, there will be a connection mount to the Dbus-daemon, while maintaining the service of the program. You can use the Dbus-send command to see which service is on top of system bus or session bus, that is, what programs are currently is associated with the Dbus-daemon: 1 View the service that is mounted on system

in the Maemo platform, D-bus is a very important middleware (middleware) solution, primarily for communication between processes. There are already a lot of services using D-bus, and then there are different ways to implement them. D-bus is run through the Maemo platform, inseparable from the D-bus. This part of the

What does the bus do? Plainly, it is used to transfer data between parts of the computer. For example, my main memory stored in the data CPU to use, need a line to pass it, the CPU internal registers between, register and Alu, CU and various parts and so on, and so on many places, in short, the parts need to transfer data The transmitted data is divided into three kinds, corresponding to three kinds of functions of the

In the front of "talking about I2C bus" and "talking about the SPI Bus", we introduce the I2C, SPI Bus for the short transmission distance, simple protocol, small amount of data, mainly for IC (integrated circuit) communication between the "lightweight" occasions. But can bus is different, can

Since I bought a car, I seldom take the bus. However, the perception of the bus for a long time, these daily Mercedes-Benz in the city on the road of the big guys, year after day, without a clear say to carry who on the road, but does not affect them always on schedule from the starting point, shun smooth to reach the end.

Now analyze the algorithm:1, Direct LineFirst of all, according to two site names to obtain the respective IDs o

---- Any microprocessor must be connected to a certain number of components and peripheral devices. However, if each component and peripheral device are connected directly with a set of lines, the connection will be complicated and even difficult to implement. In order to simplify the design of hardware circuits and system structure, a group of lines are commonly used and configured to connect with components and peripheral devices with an appropriate interface circuit. This group of common conn

Some time ago to implement a RABBITMQ message bus, the implementation of the process itself is also constantly have to think, summarize and revise. You need to consider the various dimensions: efficiency, performance, network, throughput, and even the ability to envision the possible use of the API scenarios, patterns. But can have one thing, oneself willing to do, walk, eat, take a bus when all thinking ho

Windows, Mac OS, Android also has "binder" subsystem. Linux has sockets, FIFO, shared memory and other mechanisms, which are not very good for the application layer. Kdbus attempts to create a mechanism that is similar to other systems for Linux.D-bus is the closest approach to this standard on Linux. Pros:

Time: 2016-12-12 huaqing Vision1. PrefaceThe CAN (Controller area Network) bus, which is a control LAN bus, is an effective serial communication network that supports distributed control or real-time control. It is widely used in industrial field control, intelligent buildings, medical devices, transportation and sensors due to its high performance, high reliability, unique design and suitable price, and ha

I²C transmits data between devices connected to the bus using only two lines (SDA and SCL). Each device is identified by a unique address (whether it is a microprocessor, LCD driver, memory, or keyboard interface) and can be used as a transmitter or receiver depending on the function of the device. The LCD driver may be just a receiver, and the memory can send and receive data. In addition to transmitters and receivers, the device can be used as a hos

However, this member cannot be used directly to set and read the device name.The method for kernel operation is dev_name and Dev_set_name.
