This directory is intended for project specific (private) libraries. PlatformIO will compile them to static libraries and link into the executable file.

There are plenty of drones (and other gadgets) you can buy online that use proprietary control protocols. Of course, reverse-engineering one of these protocols is a hacker community classic. Today, ...

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 ...

星标公众号，让嵌入式知识 “投喂” 不停歇！ 大家好，我是杂烩君。 今天我们来简单分享：FreeRTOS任务怎么拆、优先级怎么配、CPU 占用怎么看。 把"串口接收 + 数据解析 + 指令执行 + 结果反馈"全塞一个任务，解析环节一出问题整条链路全挂，而且任务执行时间 ...

I’m already loving this device, and I haven’t even touched one. Arduino announced it has collaborated with M5Stack to develop the new compact and powerful Nesso N1 IoT development kit. This system ...

Qualcomm subsidiary Arduino has announced the VENTUNO Q, a new single-board computer that ships with Ubuntu pre-installed. This isn’t a board aimed at casual makers or tech tinkerers bored with their ...

Abstract: Radar technology has been a cornerstone of numerous applications, from aviation to meteorology, offering invaluable capabilities for object detection and tracking. Traditional radar systems, ...

[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 ...
