Circular … WebFeb 5, 2024 · For a serial circular buffer, you need two indices. One is the front index and the other one is the rear index. When you get a character from the serial port, you place it at the location of the front index and increment the index. In your program loop, you check to see if there are any available characters. philmorA circular buffer is an array of constant length, and we use it to store data in a continuous loop. It is also known as a ring buffer because it stores the data circularly. Data is read from the buffer in a FIFO (first in, first out) manner, meaning that the oldest data is read first.We use the buffer to store and transfer … See more In this tutorial, we’ll learn the concept of a circular buffer in engineering and computer science.
