Beaglebone Black Tutorial Beaglebone black device Connection Beaglebone Black The material to be prepared before developmentAfter the above introduction, I believe you have a general understanding of beaglebone, you need to notice that the completion of one thing may have many different ways. Therefore, depending on th

Why use the advantages of Beaglebone BeagleboneCurrently, a typical microcontroller-based board is priced at about 120 yuan, while Beaglebone Black is priced at about 330 yuan. What else did you get for the extra money besides the more powerful processors?1.2.1 Built-in networkThe built-in network is not just the onboard Ethernet interface, but also all the available network toolkits in Linux. With these to

We have previously introduced the basic concepts of the CANopen bus protocol. Now we will take a look at the CANopen bus protocol equipment. First, let's take a look at the features of these devices through the following aspects. We will also know why CANopen bus is becoming increasingly popular in the market. Object Directory) The object dictionary is the centra

For beginners, compared to other bus data, in the domestic canopen data is not much. And not all materials are suitable for beginners to see. Here are some suggestions, interested in CANopen, you can refer to the order of study.Premise: Need to know about can bus, can see the data of CAN2.0 bus.Of course, the computer system, microcontroller and programming also need to have a certain foundation.The first s

To learn about networking, you must understand the bus protocol. So today we will introduce the CANopen bus protocol. This Protocol is embodied in multiple devices. For more information, see the article. The CANopen bus protocol includes the Communication sub-Protocol Communication Profile) and the Device sub-Protocol Device Profile ). Communication Sub-Protocol describes the main form of the object diction

Nowadays, many communication electronic devices are highly intelligent. To some extent, it is comparable to computers. In the communication settings, we will introduce the use of the CANopen bus. Considering that CANopen bus is a good open and low-cost Field Bus supported by most European and American manufacturers, it is necessary to enhance the study of CANopen

CANopen is a high-level communication protocol in the Control LAN road (Controller area Network, CAN), including communication sub-protocols and equipment sub-protocols commonly used in embedded systems, is also commonly used in industrial control of a fieldbus.Since the can bus only defines the physical layer and the data link layer, and does not define the application layer, the CANopen communication prot

Sync is a method of CANopen to manage the synchronous data receiving and dispatching of each node, which is equivalent to the network beats, and the synchronized PDO performs real-time data transmission according to this network beat. Sync belongs to the production/consumption mode of communication, there is only one sync producer in the network, there are generally many consumers, whose network identifier is high priority, generally set to 0x80, basi

Recently, I sorted out my information about Can, CanOpen, and J1939 on the Internet. I want to upload dozens of documents to my online storage for your reference. I don't know if it will infringe on you. If you infringe on your rights, please let us know...My Network Disk address: http://www.yimuhe.com/u.php?

Tags: OS use AR SP data on BS to manage applications 1. What are the similarities and differences between can and CANOPEN:Can only defines the physical layer and the link layer, but does not define the user layer. You can define some communication conventions on the network as needed. CANOPEN defines the user layer based on CAN, that is, the agreement between users, software, and network terminals for information exchange. 2. From the perspective of

mapping is described in Object 0x21. The following table shows that sub-index 0 corresponds to the number of objects to be mapped, and the child index 1~8 corresponds to the object to be mapped. Transmission Type　　PDO communication has three trigger modes: Internal event driven or internal timer trigger, synchronous trigger, remote request trigger. 1) Trigger synchronously. Synchronous triggering PDO refers to the CANopen node receiving a synchroniz

SDO is an abbreviation of Service data Object Interface (Obiect), as the name implies to provide service data access interface, service data is some real-time requirements are not high data, usually refers to node configuration parameters, so SDO is generally used to configure and obtain the configuration parameters of the node. Its priority is only higher than the heartbeat (Heartbeat).Since SDO is called a service, there must be a service provider and user, the provider is the SDO server, the

Beaglebone Black Development Board installation driverBeaglebone Black Development Board installation driver, before using Beaglebone Black Development Board to do anything before the first need to install the driver. The following content shows how the Beaglebone black Board driver is installed under Windows, Mac OS X, and Linux operating systems.

About the driving disorder, the author wants to use the PWM module, although Beaglebone comes with, but did not give a description of the document AH. All by groping! And some places are not right.2.
