sides of the error is a bit large, it is easy to lead to communication errors, so many serial communication protocol will have check code, such as GPS protocol, through the data frame check code can filter out due to transmission errors, avoid anomalies.The original text also has the reference code and the debugging serial port artifact, see in detail: http://um

such as tcsetattr (FD, tcsanow, newtio) Serial Port usage detailsAfter configuring the relevant properties of the serial port, you can open and read/write the serial port. It is used in the same way as file operations. The diff

Many serial peripherals are used in the automotive terminal project, such as DVD movement, GPS, Bluetooth, radar, and tire pressure monitoring. The main CPU (TCC89XX) and small MCU (STM32) through serial communication. For a moment, the serial port is a little too slow to us

sending and receiving dual-end processors with Low Speed. Therefore, hardware Throttling is required. The other pins are related to the modem. The data set ready of the DSR data device is used to indicate that the modem is in usable state. Data Terminal ready indicates that the data terminal can be used. These two signals are used to check whether the modem is connected. This pin is set by the modem when t

, this series of products provide optional photoelectric isolation (2 KV) and Surge Protection (25 kv esd) functions ｡ This product features: Optional photoelectric isolation (2KV) and Surge Protection (25KV ESD) features; Automatic Control of Data flow ADDC (Automatic Data Direction Control) features; RS-485 Data Control l: ADDC can be controlled through the RTS; built-in terminal resistance; chip hardware traffic control to ensure no data loss; adva

Serial communication When exchanging information between the terminal and the computer or between the computer and the computer, in addition to using the parallel communication mode, the serial communication mode is often used. Parallel communication refers to the data of everyone at the same time, it is a bit of data transmission speed, the disadvantage is how m

transient interference within a certain amount of energy, and the duration cannot be long. Moreover, it is difficult to implement it by having to have a good channel to connect the earth. In practical application, the above two solutions are combined for flexible use, 14. In this method, the isolation interface isolates large transient interference, while the bypass element protects the isolation interface from high transient voltage breakdown.Figure 14IX.

Understanding Serial Communications There are many kinds of serial communication protocols, such as rs232,rs485,rs422, even the popular USB is serial communication protocol. And the application of serial communication technology is everywhere. Perhaps everybody sees most is the computer

Change it to ttyUSB0 (because I am A USB-to-Serial port ). Configure the baud rate, data bit, and stop bit, and enter "E". the baud rate is 115200 8N1 (data bit 8, no parity check, stop bit 1 ), type "F" and "G" for hardware/software traffic control respectively, and select "No" (note: If this parameter is not set to "NO", you cannot enter a character on the terminal
