Pointers in C language are variables that store the address of another variable. This variable can be an int, char, array, function, or any other pointer type. The size of a pointer depends on the computer architecture. However, in a 32-bit computer architecture, the size of a pointer is 2 bytes. Consider the following example … Read more

Follow the Embedded Learning Station to get more fresh hot topics. Before discussing the learning path, let’s first understand what embedded development is. Simply put, an embedded system consists of two parts: software and hardware. It is application-centered and can achieve software and hardware tailoring. Software includes: specific business applications and operating systems (simple applications … Read more
Optimizing Program Size in Embedded C/C++ Development: Structure Optimization In <span>C</span> and <span>C++</span> programming, the memory layout of structures (<span>struct</span>) has a significant impact on program performance and memory usage, especially in embedded development where <span>RAM</span> is limited to <span>16K</span>, <span>8K</span>, or even <span>4K</span>; every byte counts, and there is no room for waste. This … Read more
What is python-ds? First, let’s understand what python-ds is. Python-ds is a Python library designed to simplify and enhance data structure operations. It provides a rich set of data structures, including linked lists, stacks, queues, graphs, hash tables, and more, along with methods for operating on these structures, greatly reducing the workload of manually implementing … Read more
This article provides an overview without technical details or usage instructions. The Zephyr kernel uses a generic data structure library, which can also be utilized in applications. The data structures include: Linked List Packet Buffer Red-Black Tree Circular Buffer It is important to note that the APIs for accessing these data structures are not thread-safe. … Read more
Overview The search time complexity of a linked list is O(N). As the number of members managed by the linked list increases, the algorithmic cost of searching increases. To address this, Zephyr provides an implementation of a red-black tree, where the time complexity for search and delete operations is O(log2(N)) for a tree of size … Read more
