星标公众号，让嵌入式知识 “投喂” 不停歇！ 嵌入式Linux开发中，线程同步是绕不开的核心场景——消息队列数据就绪、外设状态变化、多线程资源协作，这些场景下你是否遇到过这些问题？ 用轮询判断条件，CPU占用率飙升； 用sleep做延时等待，要么响应不 ...

The Zephyr Project supports a compact, multi-threaded, open-source, real-time operating system designed for IoT applications. Its small footprint and connectivity make it ideal for ...

在本文中，我们将深入探讨pthread_rwlock_t，以及通过示例代码演示如何使用它来保护线程间资源。 在Linux多线程编程中，保护共享资源是一个至关重要的任务。一个常见的场景是多个线程需要同时读取某个共享资源，但只有一个线程能够写入。这就是典型的读写锁 ...
