Each device on the IIC needs an address register to determine its own address. Each device on the IIC needs an address register to determine its own address: Many devices are used to determine the address by hardware.Some in the factory when the address is set up, the user can not change, some identified several, the remaining several by the hardware to determine (for example, there are three users determined by the user, leaving 3 control address of the pin), this class more; There are address

Nowadays, there is no uniformity in the naming of the same thing on the Internet. It seems like there are many types of things, so it is necessary to clarify the clues first, find out the equivalence relationships between different names: 1. CPU external frequency = External frequency 2. CPU frequency = clock speed 3. Frontend bus frequency 4. System bus frequency 5. MultiplierRelationships: The externa

The last time I talked about a client that was writing a RABBITMQ-based message bus in the face of concurrency problems and the final implementation of the solution. It's a simple and not prone to concurrency problem scenario, and if you read that article, I've given the pros and cons of the final implementation scenario.The core issue is whether client-created connection with RABBITMQ server is shared or exclusive. One more popular example of this pr

Last year wrote a relatively long SQL, although not how to write now. On the blog to commemorate a bit.Calculate the share rate of bus driving, the logic is as followsMorning 6 to 9 o'clock morning peak, night 16:30-19:30 late peak, the rest of the time flat peak.According to the number of passengers travelling on the Od five-minute bus (the number is calculated in the previous table), according to the peak

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

widely heard. for programming in Linux or windows, the addresses operated by the program are all virtual addresses. Virtual Address is a combination of hardware MMU and Software Memory Management to facilitate more efficient use of RAM. Memory Management is a big article. I will not talk about details here. For details, refer to the memory addressing chapter of utlk. Logical Address virtual address can be operated by software developers Based on System Programming and bare coding. 3. physical

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

The message bus and activity system penetrate into the Linux desktop-general Linux technology-Linux programming and kernel information. The following is a detailed description. D-BUS is a promising message bus and activity system that is starting to penetrate into Linux®Desktop. Understand the reason for creating it, its purpose, and development prospects. 　　 D-

The overall solution of a recent project was designed as a distributed system, so it struggled with the CAN bus or RS485 communication. Therefore, I searched some documents about RS485 and CAN bus on the Internet. In addition to further understanding of RS485 communication characteristics, I also learned the characteristics of CAN bus and its comparison with RS48

Last night, I started to check the LCD and found that the front bus was not very well mastered. Later I summarized the reasons: First, I understood the bus principle very early, and second, there was no big routine during bus learning, third, it was just returned from the Dragon Boat Festival holiday and it was not in the status. Forget it. If you don't have a re
