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

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 contro

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

After returning more than 1000 posts and judging nearly papers, I took a long breath. Recently, the serial port solution has finally been finalized, and it will soon end. Otherwise, it will take a lot of time and delay is the devil. I found a code for reference. # Include # Include # Include # Include # Include # Include # Define rxd 0 // receive# Define txd 0 // send# Define LSB 0 // The baud rate is adjus

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

On the topic "sending and receiving short messages via serial port", I will organize some technical questions I have discussed with netizens into the following text. I hope this article will help more friends who are interested in SMS. Because I am a hobbyist and have limited time and money, I have no power to test many models of mobile phones and modules one by one. There may be such errors, and I hope the
