vcds can bus

I2C transmits data between devices connected to the bus using only two wires (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 sender or receiver based on the functions of the device. the LCD driver may be a receiver, while the memory can send and receive data. in addition to transmitters and receivers, the device can act as a host or slave when

This article can realize Baidu bus line search, you can select more than one line, the specific implementation code as follows: First, the bus route details search The details of the bus line are mainly divided into two steps, 1. Get the uid,2 of the bus line. Get the details of the

Knowledge summary of LIN Bus development 2018-1-23 1.LIN Bus Introduction Lin Bus (Local interconnect Network) is inevitably used in the development of automotive electronics. As a can bus as a low-cost auxiliary bus, Lin bus in t

This period of time the message bus was re-refactored. This refactoring mainly focuses on the components of the message bus and the simplification of the pubsub client, as well as some ideas about the message bus. Simplifying the complexity of the clientThe previous client needs to connect two distributed components at the same time. Access to the message

Full stack workshop training 13 --- Android --- message bus Mechanism The blog post published yesterday tells about the content of network requests using asynchronous tasks in Android. At the end of the asynchronous task, Handler mechanism is used to notify the original Activity to update the interface. The netizen traburiss pointed out that, the onPostExecute of the asynchronous task is already in the UI thread, and Handler is used to execute the tas

Label: style blog HTTP color ar use SP strong data Reprinted please indicate the source: http://blog.csdn.net/lg2lh/article/details/8042008 The basic protocol of PCI is not introduced here. Because the General chip protocols are well integrated, I only need to know about them. I don't need to know the protocol too much because I don't have to do chips. The explanation here is based on the PLX 9054 (9052) chip. I am only a beginner and hope to criticize and correct it. I. Address in

About I2C and SPI bus protocols Iicvs SPI Currently, in the low-end digital communication application field, we can see IIC (Inter-Integrated Circuit) and SPI (serial peripheral interface) everywhere. The reason is that these two communication protocols are very suitable for close-range and low-speed chip communication. Philips (for IIC) and Motorola (for Spi) have developed these two standard communication protocols for different backgrounds and mark

1. Bus system structureThe system consists of a matrix consisting of multiple interconnected 32-bit AHB buses 8 Main bus –CORTEX-M4 with FPU core I-bus, D-bus and S-bus –dma1 memory bus –dma2 memory

1. Analysis of I²C driver in embedded LinuxThe I²c (inter2integratedcircuit) bus is a two-wire serial bus developed by Philips to connect microcontrollers and peripherals. In embedded system, the microcontroller can set up and query the components of each system at any time through the I²c bus, in order to manage the configuration of the system or master the func

the bus in arm The bus in arm is used for communication between different parts. There are two different types of devices connected to the bus: ARM processor, which is the main device of the bus, has the right to arbitrate on the bus, can initiate the data transmission requ

Even after four years of study in Wuhan, I feel that Wuhan is incomparable with Beijing in many aspects, such as city construction and quality. However, there is one aspect that Beijing envy, that's the speed of public transportation in Wuhan! Even when I see traffic congestion in Beijing, I miss it even more ......Take the bus 521 and catch up with another 521. At that time, some people reminded us to pay attention to safety. As a result, the driver
