Currently, both the on-board and PND devices have the function of automatically correcting the system time. The implementation method is generally when GPS is used (of course, for devices with CMMB module, you can also use CMMB for calibration ). However, because the serial port device is an exclusive device, the GPS serial port cannot be used by the navigation software and calibration program at the same t

Principles, differences and Applications of SPI, I2C, and UART Serial Bus 1. UART is a two-line interface. One transmission and one receiving interface can communicate with each other in full duplex mode, and the number of lines is relatively small. Data is transmitted asynchronously, with strict timing requirements on both parties, and the communication speed is not fast. It is used most frequently for multi-host communication.2. Compared

C # implement simple serial communication,Preface Based on the study and research attitude, the c # language is used to implement simple serial communication tools.I. Serial Communication Principle The concept of Serial communication is very simple. The Serial port sends and

RS-232 serial port, serial port by bit to send and receive bytes. Although it is slower than byte parallel communication, the serial port can use one line to send data while the other line to receive data. Typically, the serial port is used for ASCII character transmission. Communication is completed using three wires:

LINUX serial port application developmentSerial Port OverviewThere are two basic data communication methods:Parallel Communication;Serial CommunicationSerial Communication is a commonly used computer interface, such as RS-232-C interface. This standard requires a db25-core pin connector or a DB9-core pin connector. The chip usually has UART Controller, which can work in interrupt (interrupt mode) or DMA (Di

Commax v2.3Serial Port ing master Software Description: Commax is a professional RS232/422/485 serial port and network TCP/IP communication for data conversion software. The local serial port data is transmitted to the remote computer through the network, and the remote computer sends control commands to the local serial port to control the local
