Original address: http://blog.csdn.net/sup_heaven/article/details/8461593Just as a memo!!!A debugging Baidu map multi-marker event monitoring problem, do not know how to solve, later read the original author jz1108 only know to use closures. Think the original author jz1108 about Baidu map of the article written good, so reproduced to CSDN, in order to respect the original author jz1108, hereby explain.Before we introduced the driving navigation, today said the

Overview:I²C is the abbreviation for inter-integrated Circuit, pronounced as "eye-squared cee" or "Eye-two-cee", which is a two-wire interface.I²C uses only two bidirectional lines, one Serial Data line (SDA) and the other Serial Clock (SCL).SCL: The rising edge enters data into each EEPROM device, and the falling edge drives the EEPROM device output data. (Edge Trigger)SDA: Bidirectional data line, for OD gate, with any number of OD with OC Gate into "line with" relationship. Output stageThe

be opened. The specific operation is generally in the emergency switch beside the instructions, passengers can also follow the driver arrangement, calm disposal. ② correct use of safety hammer In addition to escaping from the car door, the vehicle can also be used to break the window glass to escape. Each bus is usually equipped with a lot of safety hammers. But the average passenger may not know how to use the s

North Bridge Chip is responsible for contact memory, graphics and other data throughput of the largest components, and the South-South chip connection. CPU is through the front-end bus (FSB) to connect to the North Bridge chip, and then through the Bei Qiao chip and memory, graphics card Exchange data. The front-end bus is the CPU and the outside Exchange data the most main channel, therefore the front-end

BackgroundBased on the design of the bus, the design idea of the internal hardware of the computer (transmitting data via the bus) is borrowed. In distributed systems, there is a need for mutual communication and remote invocation between different subsystems, the direct way is "point-to-point" communication mode, but this will expose some obvious problems: the system tightly coupled , configuration and ref

I believe that most of the fans are not unfamiliar to Alipay, in particular, the net to buy people, now Alipay in everyone's quick to use more and more widely used, and now it can be filled with bus cards, the following for everyone to pay the Po-filled bus card method, want to know how it can be filled with public transport cards to refer to. Note: Mobile phones must be NFC, it is reported that at present

Registering a SDIO driver will call the following function: /*** Sdio_register_driver-register a function driver* @drv: SDIO function Driver*/int sdio_register_driver (struct sdio_driver *drv){Drv->drv.name = drv->name;Drv->drv.bus = sdio_bus_type;Return Driver_register (DRV->DRV);} In fact, very good understanding sdio_driver is actually driver encapsulation, and the driver bus for Sdio_bus_type. The drive of this device is very simple. Look at the s

We have a list of bus routes. Each are routes[i] a bus route that the i-th bus repeats forever. For example if routes[0] = [1, 5, 7] , this means then the First Bus (0-th indexed) travels in the sequence 1->5->7->1->5->7 ->1-> forever.We start at bus stop S (initially not on

first, Otto Brief introductionOtto is the library of square launch, address: Https://github.com/square/ottoLet's take a look at Otto's official introduction.An enhanced guava-based event bus with emphasis on Android support. Otto is a event bus designed to decouple different parts of your application while still allowing them to communicate efficiently. forked from guava, Otto adds unique functionality to a

Because the socket can relates to can bus protocol, socket, Linux network device driver and so on. Therefore, in order to be able to fully understand the principle of socket can. We need to know some of the following aspects of knowledge: (1) Can bus protocol; (2) Socket principle; (3) Linux network device driver; When familiar with the following three aspects of the knowledge point, we will analyze the L

An (Controller Area Network) is a serial communication network with high reliability and support for distributed and real-time control. Can works in Multi-master mode. Any node on the network can actively send information to other nodes on the network at any time, regardless of the master or slave node, without the need for station addresses and other node information. Flexible communication. The CAN protocol model has only three layers, namely, only the physical layer, data link layer, and appl

In addition to supporting RABBITMQ's automated configuration, Spring Cloud bus supports Kafka, which is now widely used. In this article, we will build a Kafka local environment and use it to try the support of Spring Cloud Bus for Kafka to realize the function of message bus. Since this article will be modified based on the implementation of the previous rabbit,

1 basicIn the device driver often see and platform related fields, distributed in several corners of the driver, which is a more important mechanism in the 2.6 kernel, the principle of understanding it, for the future analysis of the driver is very helpful, the following brief introduction: In the linux2.6 device model, concerned with the bus, device, drive these three entities, the bus will be the device a

We have previously introduced driving navigation. Today we will talk about bus navigation. What is bus navigation? The bus navigation function tells users the bus travel plan from A to B, rather than the specific bus route information, which requires the attention of

A little understanding of the S3C2440 On-Chip Bus (AMBA)-key string structure and the S3C2440 On-Chip Bus (AMBA) Recently, I have been keeping an in-depth understanding of the S3C2440 AMBA bus, and its progress is slow. Most of the time I spent on the opening of my thesis, I can only squeeze a little time for embedded. The key string used for one year is broken,

To recap, in the previous introduction to Spring Cloud Config, we left a suspense: how to implement real-time updates to configuration information. Although, we have been able to implement the property update of the application triggering the content modification in the Git warehouse through the/refresh interface and the Git warehouse Web hook. However, if all triggering operations require us to manually maintain the application location of Web hooks, this will become more and more difficult to

The Windows Azure Service Bus allows a public connection point between the inside and outside of the Web service to connect internal and external services without changing the Enterprise Firewall or other security configurations. When using Azure cloud services, it is not scientific to use IP addresses to establish connections due to scaling. The relay service can act as a good public connection point. Of course, it is generally recommended to use a

1. Starting from the ibm pc xt architecture... In the initial PC design, CPU, ram, and I/O are connected by a bus, and all components must work in the synchronous mode, the CPU determines the frequency at which other devices operate. This will bring about a locked to each other effect, that is, everyone is limited to a universal clock frequency (clock frequency) that all devices can withstand, the overall performance of the system is not high. 2. The
