Advanced Embedded Programming: Completely Solving Data Loss Caused by Communication Data Overwrite - Ring Buffer

01Introduction The Ring Buffer (also known as Circular Buffer) is a data structure used to efficiently store and manage data within a fixed-size array. It is particularly suitable for scenarios that require continuous reading and writing of data, such as audio processing, network communication, and real-time data stream processing. Below are the basic concepts, implementation … Read more

Zephyr Kernel Data Structures - Ring Buffer

Overview The ring buffer is one of the commonly used data structures in embedded software development, storing content in a first-in-first-out manner, and is used to implement asynchronous “stream” replication of data. Zephyr provides a struct ring_buf abstraction to manage such data structures. Various drivers in Zephyr (UART, Modem, I2S, etc.), as well as shell, … Read more
