serial port sniffer

Method 1: The serial port accepts the data, the timer to determine whether the timeout accepts data completion. Method 2:DMA Accept +idle interrupts Implementation of the idea: the use of stm32f103 serial 1, and configured to idle interrupt idle mode and enable DMA receive, and simultaneously set the receive buffer and initialize the DMA. Then after the initiali

When talking about serial port parallel port, you can always think of some computer wiring. Yes, these serial ports are all related to some computer buses and plug-in cables. All these lines are managed through protocols. So today we will introduce the serial

Note: Use the virtual serial port with the last download (also uploaded 115 network disk) These days under the Win7 test a serial communication software, my notebook has no serial port, had to find a virtual serial

The basic way of the user's common data communication can be divided into parallel communication and serial communication.Parallel communication refers to the use of multiple data transmission lines to transmit a single data. Characterized by fast transmission speed, suitable for short-distance communication, but requires high transmission speed of applications.Serial communication refers to the sequential transmission of a single bit of data using a

These two days need to develop a program to implement the GSM at command into CDMA at the command set (in order to tie in with another GSM at command of the third party SMS program access to our CDMA Modem), considered, decided to use the virtual serial port of the way to achieve, Is that we develop a gateway program control modem, while in the system simulation of a new

Find a broken circuit board under the table today see a chip GM8125, the main function of this chip is to expand the serial port.GM8125 can be a full-duplex standard serial port expansion into 5 standard serial port, and through the external pin to control the

Using a serial port terminal as the Linux console, you can remove the need for additional keyboards, display cards, and monitors, and use the Linux host as an embedded black box for any purpose. It is not difficult to connect a serial port terminal to a computer's serial

The Hal Library is too inflexible to use HAL Serial port interrupt receive The HAL Library is too inflexible to use, too restrictive, and then, if you have time, you will use the registers and the HAL library to mix operations.If the use of serial port interrupt reception, after receiving data, the library did a clos

How do you want to buy a computer or assemble a computer, you first need to know some hardware knowledge, in this article for you to specifically introduce the serial port and the hard disk, and the difference between the two. I hope to help you. In order to facilitate understanding, you can understand the difference between the serial and the hard drives: Coll

In the actual development, often encountered the serial port of the default output IO port is occupied by other modules, so we have to use the serial port IO port mapping function, refers to the original implementation of the func

Connect the two serial ports with crossover lines. Assume that the two serial ports are/dev/ttys0 and/dev/ttys1 respectively, you can directly execute Cat/dev/ttys0 in a shell, then execute echo "test. ">/dev/ttys1. If both serial ports are good, executing CAT/dev/ttys0 will output 'test. "If not, you can use CAT/proc/interrupts to check whether there is any inte

First, overview:The Usart is a universal synchronous asynchronous transceiver for flexible full-duplex data exchange with external devices, which supports a variety of communication modes and provides multiple baud rates via the fractional baud rate generator.Second, serial IO:For stm32f407 there are 6 serial ports, for each serial

Solution to LINUX serial port programming Articles on Serial Port Programming in Linux are everywhere on the Internet, but most of them are from one article, and they all write some basic operations, such as controlling the Serial Port
