pending spi_message structures under Master, and the worker thread will process each of these message requests on a first-in, one-out basis, after each message transfer is complete, corresponding to the Spi_ The complete callback function of the message structure is called to notify the Protocol driver to prepare the next frame of data. This is the spi_message of the queue. When a worker thread wakes up, the relationship between Spi_master, Spi_message, and spi_transfer can be used to describe:

that the initial level of the clock signal is high. In addition, we use Cpha to indicate that the clock along the sampled data, Cpha to 0 means that the first clock changes along the sampled data, while the Cpha of 1 indicates that the second clock changes along the edge to sample data. The kernel uses a combination of Cpol and cpha to represent the working mode that the current SPI requires: Cpol=0,cpha=1 Mode 0 Cpol=0,cpha=1 Mode 1 Cpol=1,cpha=0 Mode 2 Cpol=1,cpha=1 Mode

Beijing Bus Card app how to recharge the role of the application does not say, you can recharge such an app, the specific details of the function we can Baidu to search for a detailed introduction. November 5, "Beijing card" official app officially online, there are already Android version available for download, iOS version of the one-card app is also in the design and development. The app is a one-stop online service platform for one card

In the "Query algorithm" and "associated place names and sites," two articles, has been implemented through the name or site route query algorithm, but in reality, from the beginning to the end of the journey is not necessarily the whole ride, for example, there are the following 3 routes: R1:s1->s2->s3->s4->s5 R2:s6->s7->s2->s8 R3:s8->s9->s10 If you want to S1 from the site to S7, if you use inquiry query route, there is no suitable ride plan. However, the distance between S2 and S7 is only

features are: can send and receive serial data at the same time, can be used as a host or slave, provide frequency programmable clock, send end interrupt sign, write conflict protection, bus competition protection.In this chapter, we will use the SPI of the STM32 to read the external SPI FLASH chip (w25q64) to achieve a function similar to the previous section.W25q64 is a large-capacity SPI FLASH product launched by Winbond, W25q64 has a capacity of

Tags: can use path establish Dbus execute command opensuse Modify workRecently after installing the Opensue Leap42.1, to learn about Python, I installed the Anaconda3, and added the Anaconda3 installation path to the path, but after restarting the system, "Could not Start" appears. D-bus. Can call Qdbus? "and cannot enter the system. This is mainly because the installation path of the Anaconda3 is added to the error caused by path. After trying some m

frequency of the CPU to a multiple of the external frequency, so as to increase the frequency by increasing the frequency. Therefore, after 486We are exposed to two new concepts: External frequency and frequency doubling. The relationship between them and the clock speed is the external frequency X multiplier = the clock speed. The external frequency of a CPU and today'sDay we often say that the FSB (front side bus, Front End

Bus Standard: It can be regarded as a standard interface between the system and each module, module and module.There are currently the following types:1.ISA, using a separate CPU bus clock, is IBM in order to adopt a full 16-bit CPU and launched. Thus the CPU can use a higher clock than the bus frequency, which is advantageous to the CPU performance improvement.

Computer composition principle-system bus and computer composition principle1. Basic concepts of Bus 1. Why should I use a bus? Von noriman divides computers into five parts: memory, memory, controller, input device, and output device. Many channels are required to connect these devices.2. Bus

I2C bus Definition The I2C (Inter-Integrated Circuit) bus is a two-line serial bus developed by Philips to connect the microcontroller and its peripheral devices. The I2C bus was created in 1980s and was initially Audio and video devices Development is now mainly used in server management, including communicatio

Bus, English is called "buses", that is, our Chinese "public car", which is very image, for example, the route of the public car is certain, any of us can take a public car to the route of any one of the public car site. If we compare our people to electronic signals, this is why English is called "bus" instead of "car". Of course, from a professional point of view, the

I2C bus signal timing Summary Idle bus statusThe SDA and SCL signal lines of the I2C bus are in the idle state at the same time.At this time, the output-level FET of each device is in the cutoff state, that is, the bus is released.By the two signal lines of the respective pull-up resistance to raise the level. Start

With the rapid development of related technology and China's communication market, the main network of the mainstream SDH equipment rate has risen to 10G, and 2.5G SDH transmission equipment by these more high-end equipment extrusion, network application level began to move down, gradually into the edge layer, replacing the original in the edge of the 622M equipment. On the other hand, with the rapid growth of the bandwidth demand of data and Internet service, more and more requirements are put

In the article "Query algorithm" has implemented the transfer algorithm, but, using stored procedures InquiryT2 query from "Dong Pu" to "car road intersection" of the bus route, found that it took 5 minutes to find out the results, such efficiency is clearly not suitable for practical applications. Therefore, it is necessary to optimize and improve the original transfer algorithm. In this paper, we will give an improved transfer algorithm, compared wi
