use a single-chip microcomputer to implement a time series circuit when using a timer. The time series circuit is powerful and has many applications in the control of industrial and household electrical equipment. For example, you can use a single-chip microcomputer to implement a corridor light switch with a button. After the button is pressed once, the light will automatically go off after three minutes. When the button is pressed twice in a row, the light will always go off, when the button

technology-based system, we can explore the internal device and compile its internal operation mechanism to achieve more flexible solutions than traditional instruments or PLC. -------------------- With the support of the Distributed Computer Operating System, interconnected computers can work together to complete a task. It can also be explained as follows:A configuration method for computer hardware and corresponding functional configuration method

Continue to learn iLBC Codec... 1. iLBC decoder Process 1 is the iLBC decoding process without frame loss. When the decoder receives Payload, it first parses the parameters required for decoding from bitstream. Here, the decoding parameters start from the LPC, and then start the reconstruction. The next sub frame reconstruction is consistent with the encoding sequence, the reconstructed residual signal is obtained by decoding the third-level shape/gain vector and multiplying them and then addin

MES function, as a result, mes systems in many factories are actually a hodgedge. Each system has its own processing logic, database, data model, and communication mechanism. Because mes applications are often systems that meet key tasks, it is difficult for such systems to be upgraded along with technological updates.A mes system based on a unified hardware and software platform usually uses industrial PC, PLC, HMI, and other equipment as the main c

, therefore, since its birth, PostScript Language has completely different features from ESC and PLC, and is more in line with the software design philosophy. It is a printer language unrelated to the device, that is to say, when defining an image, the characteristics of the output device (such as the printer resolution and paper size) can be ignored, and the process of processing text and graphics is the same, this brings great flexibility to the pro

Old Wu is on the road (Story 3 before the company was founded) Part 1I wrote about the reasons and motivation for entrepreneurship. Now I think it is really simple, naive, and reckless. However, according to self-denial and self-improvement, we call it "a little effort to do things when you are young". Thank you for your praise. This article will write the first barrel of gold. I mentioned in the previous article that my girlfriend is a salesman in a small software company. It was about a mo

Inc. indicates the nature of the company. Company limitid is usually abbreviated to CO. LTD. or simplified to Ltd. But it only refers to the nature of the company, which is a limited company and not any other company. Company should not appear between the company name and Co. Ltd, because Co. already contains the company's meaning. Again, incorporation means:Company/registration/merger. If it is added after the company name, it is mostly in the form of word segmentation, but it has become an inh

the OPC server uses the OPC custom interface. The software consists of two modules: OPC data collection and data storage. The Win32 Multi-thread technology is used for communication between modules. OPC Data Collection is used as a working thread to run in the background. Data Storage is the primary thread of the system. The thread function of the worker thread cyclically reads data from the OPC server, and the data changes constantly start the writing events of the master thread. In addition,
