1. the generation and development of CAN Bus Controller Local Network (CAN-Controller Area Network) is a multi-host Local Network launched by Bosch for modern automobile applications, its outstanding performance has been widely used in industrial automation, a variety of control equipment, transportation tools, medical instruments, construction, environmental control and many other departments. The local network of controllers will be popularized in C

limitations when accessing data over an Intranet or Internet. You are also responsible for implementing data synchronization between front-end and back-end systems, handling distributed change tracking, and dealing with problems that occur when used in an occasionally connected environment. The smart client applications discussed in this article can be built using Windows presentation Foundation (WPF) or Silverlight. Because Silverlight has a subset of the WPF features, the techniques and meth

S3c_set_platdata (PD, sizeof (PD), s3c64xx_device_spi0); The above function is to specify the GPIO configuration that the controller uses, the number of slices of pins and the clock configuration. This information is used in the subsequent controller driver. registering the platform_driver of the SPI Controller In the previous section, we registered the SPI

Give the car to the users of the software to detailed analysis to share the query bus tutorial. Tutorial Sharing: 1, first open the car to the app, positioning your current city; 2, in the Home page, click on the Search bar, you can search the bus lines, stations, locations to conduct real-time inquiries. Well, the above information is small make up for the car to the users of

GStreamer bus system is mainly used to provide users with internal elements event information. Using the GStreamer bus system, just call Gst_bus_add_watch and register a callback. The problem, however, is when the interface is invoked, and the thread used to handle the bus event. The callback is implemented internally with the glib source mechanism, and the sourc

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

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

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
