the highest bit smod is related to serial communication. Smod = 1, and the baud rate doubles based on the original; Otherwise, do not double. Iii. Calculation of baud rate For methods 1 and 3, the baud rate is calculated as follows: (2 ^ smod/32) * (overflow rate of T1 ); For method 2, fosc * (2 ^ smod/64 ); The method 1 is determined by the crystal oscillator and is a fixed value. T1 is the timer 1. When the baud rate generator is used, it is genera

The Universal Synchronous Asynchronous Transceiver (USART) provides a flexible method for full-duplex data exchange with external devices using the Industrial standard NR asynchronous serial data format. The Usart uses a fractional baud rate generator to provide a wide range of baud rate options, supporting synchronous one-way communication and half-duplex single-line communication.1, STM32 firmware Library use of peripheral equipment, the main ideaIn

Use Windows Super Terminal to debug modem and serial port.The Super Terminal is a serial port debugging tool provided by windows. It is easy to use and widely used in the Basic Debugging of Serial Port Devices. 1. Attachment/communication/Super Terminal. In the naming conne

In Linux debugging serial program, but the following hardware is not in place, so, think of their own simulation of a serial port for use. Try the following code:#!/usr/bin/env python#Coding=utf-8ImportPtyImportOSImportSelectdefmkpty ():#Open a new TTYMaster1, slave =pty.openpty () slaveName1=os.ttyname (slave) master2, slave=pty.openpty () slaveName2=os.ttyname

1, learning USB time to play, feel the USB is really too complicated, read a book to see the head big, feel completely chaotic, as if not remember things like, hey 2, just do this, first engage in other to learn USB knowledge. 3, this STM32 analog USB to the serial port is a transplant official website of a routine, found that the official website of this routine bug still a lot, hehe 4, copy the code of th

21ic bought a 1 yuan movable board, transplanted RTT (RT-THREAD) Chinese embedded operating system. the system can run normally. Then, according to the tutorial on the RTT official website, a serial port driver is written. It was originally defined as the uart1 port, but the usart1 pin of the Board was not found. Although the stm32 can be mapped, there is still

Serialapp-ZigBee serial port application instance this example application Z-stack version ZStack-1.4.3-1.2.1 The serial application of serialapp in Z-stack is used to connect two cc2430eb boards to the computer through serial port, and data is transmitted to each other. The

The serial port receives sends the data to have two kinds of ways, one is the interrupt mode, the other is the DMA way, here mainly in the interruption way, looks at uses the serial port to send, receives the data the entire process. Here is an example of the Serialapp routine. Call the Haldriverinit () function in the
