the working mechanism of ROS: Simply put, Ros is a DistributedThe operating system communicates and controls through node nodes, subject topic, service services, etc. This mechanism is like two people chatting, everyone is a node, this software chat function is topic, two people only through to chat, if a person with whatsup, another person with, is not receive the other party information. And the service is like the expression pack or the circle of friends, two people chatting at t

a UART-to-do its serial communication. For those familiar with the Arduino, the Tx/rx pins on an Arduino is the the and the main UART pins. In its more basic form the UART hardware consists of a transmit (TX) line and a receive (RX) line. The software configures how fast data was sent (the baud rate) and the specifics of the protocol.Baud Rate　　Since The UART module is asynchronous, there are no external c

Late 1,Flash storage: In the Easyflash to increase the log storage, read function, so that Easylogger and its seamless docking. So that the log can be stored more easily in the non-file system , and has the function of historical day retrieval; 2, configuration file: File system under the configuration file; 3, File transfer: File system supporting files according to the c

Since the first set of mechanical keyboard, has modified the interface scheme, installed LED lights, etc., but always can not meet their DIY desire.So the simplest way to think of it is to use a ready-made master, and the master comes from an abandoned keyboard, such as:This master control is also the matrix mode, only need to measure the corresponding key and then weld the line, complete the diagram as followsUsing the O 5-foot red axis mechanical shaft. Friends who play LOL should be familiar

MachineryCATIA SolidWorks function is too weak, often crashes, UG finite element analysis ability is not strong; CATIA is used to develop aircraft, optimization design ability should be weakDrawings-Supports dynamic editing (parametric constraints), see Modeling-programming control (see http://cdmd.cnki.com.cn/Article/CDMD-10143-1012316916.htmResearch on kinematics simulation of industrial robot based on CATIA+V5Adams to see if CATIA can complete the basic kinematics simulation and multibody dy

The world's leading semiconductor supplier and the world's leading arm? Cortex? -STMicroelectronics (ST), a m microcontroller manufacturer, further strengthens the ease-of-use and design flexibility of the stm32 series microcontroller, and releases a cost-effective and easy-to-expand prototype development board for all stm32 products. Stm32 nucleus o perfectly integrates ease of use, flexibility, connection functions, and compatibility with mainstream tool resources. It is an ideal development p

Every time I use a microwave oven to eat something hot, I feel bored, and I can't do anything at all. Four students at the University of Pennsylvania recently converted a microwave oven named μwave to help us eliminate this boring wait. After each set time, μwave automatically finds the same video from YouTube for you to view. Time Matching is very useful and won't make you feel half sorry. It doesn't matter what you find. It's just like a lot of people are watching the news. As a work complet

What are the PHP reference books? Please ask what types of books are on the board. For example, the computer as a server in the form of Yifi can be used to do the receiving of information or exchange of information between the motion Ditto in 3G mode Is that these types of [programs] don't know if there's any teaching Basically, all the books I've read are teaching the basics. For example, how the form is built ... Computer (server side) and computer (client) between the passing information I wo

development field, the main development tool is Keil or IAR, this development more accurate is the single-chip development or hardware development, and the recruitment of embedded development, development environment is based on the Linux operating system, this development is generally divided into several levels: drive development, Operating system layer development, application layer development. The knowledge needed to develop the latter is not at the same level as the former.If you've playe

Recently done projects, using the Arduino control device, read data, and then transfer to the server via the mobile network.I chose the sim900a module of the hot atom. A listener is deployed on the server, and the Arduino control sim900a sends the data to the server by means of TCP.One day, suddenly think, sim900a can visit the webpage? If you can, it is easier to submit the data directly through the Web pa
