1Introduction Regarding the issue of automatically identifying the UART serial port baud rate, those with project experience or who have studied serial ports should know a little about the methods for automatic identification. Most likely, the common knowledge is to achieve this through baud rate matching, which is the most common and effective method. The … Read more
The Concept of Queue Before we start, let’s review the basic concept of a queue: Queue: A linear structure that follows the First In First Out (FIFO) principle, allowing insertion at one end (enqueue) and deletion at the other end (dequeue). Characteristics of a Queue Similar to a ticket queue, the first person to arrive … Read more
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
