C # the serial communication tutorial Simplifies everything and only retains the core functions. This is probably the easiest to understand, For details about the serial port definition, see. C # With the support of the powerful. Net class library, you only need to perform the following three steps: 1. Create 2 open 3 send/accept 1 Creation: 1. The namespace req
1. register the mscomm32 control, download it online, and copy it to the c: \ windows \ system32 folder. I installed a 64-bit win7 System in C: in the \ windows \ syswow64 folder, open cmd, write the code regsvr32 c: \ windows \ system32 \ mscomm32.ocx, and press enter to prompt you that the registration is successful. 2. in the dialog box, add a control: Open the toolbox-> right-click and select items. After a while, select the Toolbox item. Under the COM component, find the mscomm32.ocx item

The previous DOS system provides the ability to communicate with a serial interface via DOS interrupts and BIOS interrupts. In the Windows environment, the development tools of C + + do not provide specific serial communication control methods like DOS and BIOS, nor allow users to directly control the interruption of the seri
In the C # serial communication development process, some home only provide communication protocol, this time developers to their own according to the protocol to encapsulate the method, some of the home more humane to provide a packaged communication protocol method for developers to call.1.

RXTX is a cross-platform serial communication component library, which is compatible with SUN's Java (tm) CommunicationAPI standard (except for the package name, the rest are the same), and RXTX is cross-platform, currently, the supported platforms include windows, linux, mac, Solaris, and wince (recompilation required ). In comparison, although sun's CommunicationAPI3.0 standard package also supports linux
The PS Key pskey_deep_sleep_wake_cts (0x23c) can is set to allow a transition on the UART CTS line to WAKE the host from D Eep Sleep; This can provide an alternative to sending a short "wake up" packet. 3.2.2. Wake with Pio The PIO port continues to drive output signals when the chip drops into deep Sleep. For a button on a headset, a common technique are to route the button's signal to an input PIO pin and also to the UART CTS Line. Activity on the CTS line can then

Because the project needs to write a host computer software, the previous period of time to contact QT, that the Framework class library will be better than MFC, and has cross-platform features, so the use of Qt5.2 wrote a serial communication based debugging host computer.Major problems encountered:1, the serial port can receive data, but the reception speed is
Sometimes you have to output the information of the Board to the computer to debug or the like, or the data collected by the sensor display to the computer.Of course, this is just the most basic serial communication, simply speaking, there is a USB cable attached.There is no function on mbed that can show printf. Need to configure it yourself. I use Win8, only to talk about Win8.1, download the driver of th
Serial Communication and overlapping I/O Windows 32 extends the file concept. Whether it is a file, communication device, named pipe, mail slot, disk, or console, it is opened or created using the createfile () API function. The declaration of this function is:Handle createfile (Lptstr lpfilename, // file nameDWORD dwdesiredaccess, // Access ModeDWORD dw

Since there are so many people asking this style, Beibei wrote it to Visual C ++ 4.2. Window 95 serial communication function set (only applicable to 32 bits) It should be noted that this is part of my program, so there are some parts irrelevant to the specific application.But I think the key is the principle, not the program itself. I will introduce it later to help you understand this long program. Heade
