The Mycom is a serial communication class. The following is the serial communication test program source code, will mycom class in this project, you can achieve a simple serial communication, I hope readers through this program to the serial communication process has a preliminary understanding: Using System; Using

Many app or game account is bound phone serial number IMEI or Mac, sometimes the phone is a friend spoof, resulting in an account is blocked, unable to reproduce the registered account, what can I do? Share a little secret today to register your account again in this case.First of all, we download and install a stone-cut simulator on the mobile phone, the function of the stone-cut simulator is to allow the mobile phone to simulate the new IMEI and Mac

The RS232 interface is a standard for serial communication jointly developed by the American Association of Electronic Industry (EIA) and bell system, modulation regulator manufacturers and computer terminal manufacturers in 1970. Its full name is "Technical Standard for Serial Binary data exchange interfaces between data terminal devices (DTE) and data communication devices (DCE)", which requires a 25-pin

1. Check whether the kernel supports USB to serial port 2. Set minicom 3. link the android Development Board and restart the system. Note: 1, if not normal link, please check the serial first TXD-RX, RXD-TX, GND-GND is correct, link OK, you can see the onlie, instead of offline. See the figure below: 2. If the minicom file is garbled, enter gedit. bashrc, add the export lang = zh_CN.UTF-8 at

Properties set in the control serial port Cache size. It is recommended that the data received per second be more than 10 times Important: this setting is important when the data volume received in the cache triggers a notification event. It is best to set no more than 10 trigger events per second. That is, when the amount of data received per second is 1000, set 100 ~ 400 trigger. This problem is time-consuming. For later reference, the following is

Hybrid application development-Serial Communication (1), application development-Serial CommunicationCRC verification 　　Cyclic Redundancy check(Cyclic Redundancy Check, CRC) is a hash function that generates a short fixed-digit verification code based on network data packets or computer files, it is mainly used to detect or verify possible errors after data transmission or storage. It uses the division and

The 16c2550 serial port chip can be used to expand two serial ports. Its operation method and register usage are exactly the same as 8250, so we can use the classic 8250 driver in Linux to drive st16c2550. 8250 the driver remains unchanged. You need to add the 16c2550 initialization code. In the initialization code, you need to set the chip selection and IRQ pin for 16c2550, configure the read/write timing

Win32 serial Programming Author: Han yaoxu In industrial control, Industrial Computer (generally based on Windows) often needs to communicate with smart meters through serial ports. Serial Communication is convenient and widely used.Generally, the Industrial Computer communicates with each smart meter through RS485 bus. The RS485 communication mode is half-du

Serial port is commonly used in the data transmission between the computer and the external serial device, because the serial communication is convenient and easy to use, so widely used. Now the international serial port new technology and new specifications launched, in combination with all aspects of social needs, th

In Win32, two programming methods can be used to implement serial communication. One is to use ActiveX controls. This method is simple but not flexible. The second is to call Windows API functions. This method can clearly master the serial communication mechanism and be free and flexible. This article only introduces the API Serial Communication Section.
