Basic Principles of Arduino Serial Communication Communication Methods and Implementation Serial communication is a method of transmitting data in a bit-wise order. In Arduino, serial communication is mainly achieved through UART (Universal Asynchronous Receiver-Transmitter). UART utilizes two pins, TX (transmit) and RX (receive), to complete the data sending and receiving tasks. Data is transmitted in … Read more
Some serial port tools do not support a baud rate of 1500000. In this case, it is necessary to make modifications. This article takes the Rockchip RK3562 Development Board as an example to introduce how to modify the system serial port baud rate on Linux. Note: The serial port baud rate of the Rockchip solution … Read more
Your device connects to the other device. If it can automatically detect the baud rate without knowing the other party’s serial port baud rate, wouldn’t it be very convenient? 1 Overview Regarding the issue of automatic detection of UART serial port baud rate, those with project experience or who have studied serial communication should know … Read more
