星标公众号，让嵌入式知识 “投喂” 不停歇！ 大家好，我是杂烩君。本篇整理了FreeRTOS的一些经典问题。 FreeRTOS 有 5 种任务状态。关键点：任务状态不是通过 TCB 中的成员变量存储的，而是通过任务所在的链表隐式表示——在就绪列表中就是就绪态，在延时 ...

[导读]在嵌入式实时系统开发中，任务调度延迟直接影响系统的响应速度和确定性。FreeRTOS作为主流开源RTOS，其调度机制设计直接影响着系统性能。本文通过硬件测量与软件分析相结合的方式，深入探讨任务调度延迟的测量方法与优化策略。 在嵌入式实时系统 ...

[导读]在实时操作系统(RTOS)驱动的嵌入式系统中，中断服务例程(ISR)是响应外部事件的"第一道防线"，其执行效率直接影响系统响应速度。以FreeRTOS为例，尽管其任务调度机制高效，但中断延迟仍可能成为性能瓶颈——尤其在工业控制、汽车电子等高可靠性场景中 ...

IT之家3 月 5 日消息，据外媒 linuxiac 报道，近期 FRANK OS 开发团队正式推出了 1.0 正式版，该系统定位轻量级，面向基于 RP2350 微控制器的硬件平台，主打 Windows 95 复古外观风格。 据介绍，FRANK OS 并未基于 Linux 内核开发，而是构建在 FreeRTOS 之上，项目开发者自行 ...

星标公众号，让嵌入式知识 “投喂” 不停歇！ 大家好，我是杂烩君。今天继续来分享FreeRTOS相关的内容——队列 Queue。 队列本质是一块连续内存，被划分成等大小的槽，每个槽存一个数据单元。发送方把数据拷贝进槽，接收方从槽里拷贝出来——两边是独立 ...

Abstract: This work studies the reliability of a FreeRTOS operating system when affected by Single Event Upset faults. The methodology is based on fault injection to target the most relevant variables ...
