Principles, differences and Applications of SPI, I2C, and UART Serial Bus 1. UART is a two-line interface. One transmission and one receiving interface can communicate with each other in full duplex mode, and the number of lines is relatively small. Data is transmitted asynchronously, with strict timing requirements on both parties, and the communication speed is not fast. It is used most frequently for multi-host communication.2. Compared

Arrive at the bus station on time today and get ready to take the bus. The bus stop is only one stop away from the bus stop. It takes up to three to five minutes to ride a bike. Because there is a traffic light intersection, the light change time is about 2 minutes. There are many

I believe that you have gained some understanding of this bus protocol through a series of articles on the CAN bus protocol. Now let's summarize this agreement. First, let's take a look at the bit timing requirements of the CAN bus protocol, and then we will analyze the characteristics of the CAN bus protocol. CAN

This blog post for the original blogger, please specify the reprint.Urban public transport and metro data reflect the urban mass transit, and the data can be used to excavate the city's traffic structure, road network planning, bus location and so on. However, such data is often held in a specific sector and is difficult to obtain. Internet map has a lot of information, including bus, subway and other data,

Forward the blog about I2C by Mr. Netease DP, which is easy to find during learning.Recently, it was found that the primary device reset may cause an I2C deadlock when accessing the I2C device. The result is high in the SCL and low in the SDA. After that, it is found that the I2C bus is pulled from the device. After the power is down from the device, SDA becomes high and becomes available after power-on The message is normal. After that, SDA will au

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

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

Duanxx STM32 learning: stm32 bus AMBA, AHB, APB A few days ago I looked at the main peripherals and circuit design of STM32. Today I began to look at the program design of STM32. Here I am using the STM32 library V3.5, so I am too lazy to see what registers The first problem encountered was the internal bus ahb and APB of STM32. Here I checked some information and recorded it.AMBAAMBA (Advanced Microprocess

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

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

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

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.

In the previous article, we briefly introduced the content of the CAN bus protocol. Now let's take a look at the physical layer and packet type of the CAN bus protocol. Based on my previous learning experience, I know that in the protocol, we usually use the packet structure and frame form for data transmission. The CAN Bus Protocol has a similar definition. The

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
