A recent attempt to migrate a gateway program from the VxWorks platform to the Linux platform. In the serial port has encountered some problems, here record.First, under VxWorks, use the devs command to view the device: -> devs DRV name 0/null 1/tyco/0 1/tyco/1 2/pcconsole/0 2/pcconsole/1 9 Host: 4/ram 11/vio 4/ahci01:1 value = 0 = 0x0 The source program used the

rate)Baud rate of Mode 3 = (2^SMOD/32) • (T1 overflow rate)Fosc is the crystal oscillator frequency. The Smod is the highest bit of the Pcon register. T1 overflow rate is the frequency of timer T1 overflow.T1 Overflow Rate =fosc/{$ * [256-(TH1)]}Mode 1, when the timer is full overflow, automatically enter the interrupt service program, and then we need to manually again to the timer to install the initial value.Mode 2, when the timer is full overflow, the single-chip opportunity automatically i

I found a lot of good information when studying the stm32 serial port to receive sending interruptions, and now the backup is here. For your reference and convenience. TC === txe By the way, I will write a post about serial port data processing recently, starting from query and interruption, as well as data processing

Tutorial 12: Serial Port module ①-send The serial port is a typical experiment, and many of you may have done a bad job, but I will introduce it as an example. We know that the serial port can be sent and received. The objective o

Author: gauss (resend) Source: www.linuxforum.net uses a serial port terminal as the Linux console, eliminating the need for additional keyboards, display cards, and monitors, while Linux hosts can be used as an embedded black box for any purpose. It is not difficult to connect the serial port terminal to the computer'

Chip Microcomputer have two usart modules and two sets of independent register groups; when the following register hits, X indicates 0 or 1, 0 indicates the register corresponding to the 0 module, and 1 indicates the register corresponding to the 1 module. Among them, the control bits related to the serial port Mode settings are located in the uxctl register, the receiving-related control bit is in the uxr

Virtual serial port is occupied, software available Serial Port Limited COM1-COM4, how to release and delete the occupied serial port A: You can delete a numeric entry in the Registry to clear these configurations: Enter Regedit

We have explained a lot about the configurations of CISCO switches. Here we will mainly explain the port security configurations of CISCO 3550 switches. Scenario: There is a CISCO3550 switch in a certain unit. For the sake of network security, the security requirements for some ports are high, that is, only the specified host can be connected, for example, if you
