You may not be familiar with this topic any more. There are a lot of online materials, because this is an important aspect of programming in Linux, and there are many people who understand this aspect; here I just want to give a brief introduction to this knowledge for beginners:To put it bluntly, serial programming connects the computer to the machine to be controlled with a serial port, and then sends specified data or controls to the lower computer through programming, or transmission, and th

baud rate bit/s. The default value is 9600. Bit Rate = baud rate X binary digits corresponding to a single modulation state. RS232 is to use a maximum distance of 30 m on close-range transmission. RS485 is used for long distance transmission with a maximum distance of 1200 m 3. databits: Get or set the length of standard data bits for each byte. The default value is 8. When a computer sends an information package, the actual data is not 8 bi

CDB ("STC"), then save the exit and add it. (If it is Kile3, then Uv3,kile4 is UV4)To use: When setting options for the target, click on the Device page and select STC in database. When you create a new project, select "STC" in the Select a CPU Date Base file.Note: The STC database provided by Acer's official website is REG51.H

they meet the different user's display requirements. (3) When doing integration projects, the diversity of input and output data. First of all we want to integrate other manufacturers of equipment, to the platform software is very convenient to access. Second, there are a lot of other manufacturers to integrate their own home equipment, on the issue of output data involved. There is no uniform standard and it is very diverse. (4) The multiplicity of communication links, for the same device may

Modicon (Modicon), a standard communication protocol used in electronic controllers. Through the Modbus protocol, the controller can communicate between each other, the controller through the network (for example, Ethernet) and other devices. At present, in the rs232/rs485 communication process, the control equipment produced by different manufacturers is widely adopted Modbus protocol into an industrial network for centralized monitoring.

simple. To improve this, you only need to do the following: in terms of hardware, add hardware circuits for specific mobile storage media, while in medium and large systems, hardware circuits related to mobile storage media (such as SD card and CF card) are ready-made, so the hardware can be ignored. Inside the BootLoader program, you only need to add instructions for storing and accessing mobile storage media (such as CF cards and SD cards) based on the file system. Based on the existing hardw

It is based on the ARM920T core and can process up to 200 MIPS, at the same time, the processor is configured with USB, Ethernet, infrared serial port supporting RS485, IIC, SPI, SSC, and other output interfaces, which are used to develop embedded products more conveniently. Note that because many processors have limitations and are not described in the processor technical materials, you must carefully read the processor metric description.

Generally, it supports programming in several advanced languages at the same time. Generally, different communication protocols can be used for communication between the upper and lower computers, or RS232 serial communication or RS485 serial communication, when using a compu

Serial Port is short for serial port, also known as serial communication interface or COM interface. Serial communication refers to the communication mode that uses the serial communication protocol (Serial Communication) to transmit data from one bit to one bit on a signal line. Serial Port according to electrical standards and protocols, including RS-232-C, RS-422, RS485 and so on. 1. Serial Communication In serial communication, data is

, you only need to log on to the video server over the network to view the monitoring images. Because of the TCP/IP architecture, the video server is very convenient to use. Any monitoring site only needs an IP address and can be configured with a fixed IP address to install the video server. A standard video server also requires RS232, rs422, or RS485 control interfaces and level input/output interfaces. The serial port can be used to conveniently im
