The best part about real-time OS (RTOS) availability in 2024 is that we developers are positively spoiled for choice, but as a corollary this also makes it a complete pain …read more Continue reading Making Sense of Real-Time Operating Systems in 2024
If operating systems weren’t so useful, we would not be running them on every single of our desktop systems. In the same vein, embedded operating systems provide similar functionality as …read more Continue reading Getting Started With FreeRTOS And ChibiOS
Back in 1996, the Tamagotchi was a triumph of hardware miniaturization. Nearly 25 years later, our expectations for commercially designed and manufactured gadgets are naturally quite a bit higher. But that doesn’t mean we can’t be impressed when somebody pulls off a similar feat in the DIY space.
The Xling …read more
Security researchers have found serious vulnerabilities in FreeRTOS, an open source operating system that’s commonly used in embedded devices including those in smart homes and critical infrastructure. FreeRTOS is a lightweight real-time operati… Continue reading FreeRTOS Flaws Puts Many IoT, ICS Devices at Risk
The FreeRTOS operating system widely used by IoT devices can be abused by computer hackers to take down the instances. A team of security researchers recently announced that it contains many bugs allowing hackers numerous pathways to the target IoT…R… Continue reading A Multitude of Freertos Security Bugs Allow Hackers to Abuse Iot Devices
The bugs let hackers crash IoT devices, leak their information, and completely take them over. Continue reading AWS FreeRTOS Bugs Allow Compromise of IoT Devices
A security researcher has discovered several critical vulnerabilities in one of the most popular embedded real-time operating systems—called FreeRTOS—and its other variants, exposing a wide range of IoT devices and critical infrastructure systems to ha… Continue reading Critical Flaws Found in Amazon FreeRTOS IoT Operating System
[Michael Becker] has been using FreeRTOS for about seven years. He decided to start adding some features and has a very interesting C++ class wrapper for the OS available.
Real Time Operating Systems (RTOS) add functionality for single-thread microcontrollers to run multiple programs at the same time without threatening the firmware developer’s sanity. This project adds C++ to the rest of the FreeRTOS benefits. We know that people have strong feelings one way or the other about using C++ in embedded systems. However, as the 24 demo projects illustrate, it is possible.
One nice thing about the library is that …read more
We live in a connected world, but that world ends not far beyond the outermost cell phone tower. [John Grant] wants to be connected everywhere, even in regions where no mobile network is available, so he is building a solar powered, handheld satellite messenger: The MyComm – his entry for the Hackaday Prize.
The MyComm is a handheld touch-screen device, much like a smartphone, that connects to the Iridium satellite network to send and receive text messages. At the heart of his build, [John] uses a RockBLOCK Mk2 Iridium SatComm Module hooked up to a Teensy 3.1. The firmware is …read more
