Communication Mode Parallel Suitable for short distance communication, the parallel communication control is simple and the relative transmission speed is fast (8 bits are transmitted together). Serial Can only be transmitted by one person. Sync (Understanding) Establish the direct control of the receiver clock by the sender clock, so that the two sides achieve full synchronization. At this point, the distance between the bits of the transmitt

Environment:Alicloud ok6410a Development Board, Windows ce6.0 System Recently, GPRS communication has been implemented, but the GPRS module (q2403a) on hand is a five-line serial port (rxd, txd, Gnd, RCS, CTS), and the boss is reluctant to buy new modules. Therefore, you need to change the debug serial port COM1 to a common serial port (this is also the 5-line

Installation Configuration minicom-------------------------------------------------- # lsmod | grep usbserial(If you use the serial port directly, but do not use USB to switch serial device, this step can be skipped) If there is usbserial, the system supports USB to the serial port. Install minicom (fedora comes with minicom, this step can be skipped) apt-get I

Winform serial communication platform, winform Serial Communication Next to the last card reading, you need to make a weighbridge read. The following figure shows how to read the lbs. The weighbridge always sends data to the serial port, so it is necessary to intercept the data to determine whether the data is legal and then calculate the result. I encountered a

C ++ hardware information to obtain the hard disk serial number and the hard disk serial number This section describes how to obtain the serial number of a hard disk, not the serial number of a hard disk partition. The core is throughDeviceIoControlInterface to obtain the version and data information of the hard disk.

The following problems exist: 1. after the device is connected, you must use software such as the serial port assistant to open the serial port and disable the software before using php to send the at command for reading the serial port. Otherwise, the device will be suspended, why? 2. Why can't I receive text messages from telecom phone numbers?

This requires the use of Java to communicate with the serial port. Serial Port Java code has been developed, but it cannot always debug programs at the p

Analog serial port Driver Based on Listen 8 common IO port The format of standard serial communication data is:Start bit (1) + Data bit (8) + check bit (1) + stop bit (1) Another important part of serial communication is to set the baud rate,The baud rate is the number of bits transmitted by the serial port w

(1) ft232r: ftdi (www.ftdichip.com) recently released a USB Interface Conversion Chip to convert USB to serial UART interfaces, or to synchronize, asynchronous bit-bang interface mode. Ftbench is a real cross-platform solution. It has versions suitable for various operating systems. It is prepared for the Linux kernel and the source code is open. It is part of the Linux kernel. It is easier to design and use this chip. The specific model is ft232rl. T

In general, only the root user can access the serial device using PuTTY, if you want to increase access to the serial device for ordinary users, you can follow the following steps:(for example, Ubuntu 14.04.3 system, the first serial device will be recognized as a /dev/ttyusb0)(1) Enter the catalogue /ETC/UDEV/RULES.D(2) New file 70-ttyusb.rules(3) Add the follow
