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
Previously, we discussed a lot about MATLAB vectors and matrices. In this chapter, we will discuss multidimensional arrays. In MATLAB, all variable data types are multidimensional arrays; a vector is a one-dimensional array, and a matrix is a two-dimensional array. First, let’s look at some special types of arrays. Special Arrays in MATLAB In MATLAB, … Read more
