In the previous article, you should know which interface your printer uses. After connecting the printer to the computer using the data cable, select the appropriate port in the driver to print it. The following describes the serial port printer driver operation steps. 1. Select the correct port number in the driver. You can view the serial port number of your computer in the Device Manager. (For WINXP, rig

The registers associated with the serial 1 interrupt are IE, iph, and IPSerial interrupt allow bit ES in interrupt allow register ie.The total interrupt of the EA:CPU allows the control bit, EA=1,CPU open total interrupt, ea=0,cpu off total interrupt. Each interrupt source is controlled by the EA first, followed by the interrupt of each interrupt source to allow control bit control.Registers IE2, IP2H, and IP2 associated with the

Now most of the LG TV comes with a serial port (RS232), in fact, through this serial port can completely manipulate the LG TV, and the function than with the remote control powerful. By using the serial port to send instructions, you can do some simple operation of the TV, such as Switch TV, adjust the volume, Exchange channels. You can also perform complex contr

There are two ports that can be controlled for serial blocking (simultaneous control of Read and write): One is the opening of the serial port, whether the open function with O_ndelay, the second one can be opened after the serial port through the FCNTL () function to control.Definition of blocking:For Read,block refers to when the

Neither the terminal nor the console is the concept of personal computers, but the concept of a small, medium-sized mainframe computer shared by many people.A host, even a lot of terminals, the terminal for the host to provide a human-computer interface, everyone through the terminal using the host resources. The terminal has two kinds of character dumb terminal and graphic terminal.Console is another human int

In order to make this experiment more obvious, I will use the serial interrupt, in the interrupt service program to read the serial number input, and then display the value on the digital tube. First, the digital tube configuration Before carrying out this experiment, we need to use the digital tube for the display of the experimental results, first of all, we require the truth table of the digital tube, I

Arm Embedded systems often encounter multiple serial port application requirements, and arm chip system native UART number is limited, so it is necessary to extend more interfaces through other high-speed bus. In this paper, Toradex based on the NXPI.MX6D/6Q processor Apalis i.mx6d/q arm computer module, the Linux system through the Exar scheme to expand the 8-channel serial port. The Apalis i.mx6d/q module

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 initialization is completed, when the external to the

Previously, when I was playing gec2410, I had the idea that I was debugging it in Linux. Because the target board is powered or the serial port sent to the PC during the reset, this was already implemented in windows, so I wanted to see the results in Linux, but after setting up a serial port in Linux, I found no response at all. I thought I did not install the cross-compilation environment, so after instal
