  • Integrating rustix on NuttX
    Hi Rust experts, we are willing to integrate rustix on NuttX RTOS, the initial effort was done by rustix author: https://github.com/bytecodealliance/rustix/tree/nuttx but it hit the wall since we don't know the right way to integrate cargo with the old-school NuttX's Makefiles. Any help or suggestion is welcome. More about NuttX here: https://nuttx.apache.org and here: https://nuttx.apache.org/docs/latest/. Source: over 1 year ago
  • Embedded Systems Weekly #116
    Open Source Autopilot for Drone Developers PX4 is an advanced and open source autopilot flight stack for drones. PX4 can flight completely autonomously for pre-programmed missions, or, obviously, it can help a pilot who remote-controls the drone. It runs on NuttX RTOS. - Source: dev.to / over 1 year ago
  • Anyone know of exceptional open source RTOS C projects?
    You should definitely have a look at NuttX. Source: over 1 year ago
  • Query: Alternatives to Zephyr?
    Maybe Nuttx can be an alternative. Have a look: https://nuttx.apache.org/. Source: about 2 years ago
  • Jump up to embedded programming from Arduino
    If you are going to use STM32, try Nuttx. Nuttx is an RTOS so you don't have to write all the drivers, interrupts, etc. Yourself but you do need to write your own applications and tinker with the protocols, pinmaps, etc. And have a decent understanding of how everything works. A good starting point is to watch Nuttx channel on YouTube. Source: almost 3 years ago

  • Debugging FreeRTOS with QEMU in VSCode
    In this post, I will step through an example setup that shows how to debug a FreeRTOS application in the Visual Studio Code (VSCode) editor using QEMU to emulate an Arm Cortex-M3 microcontroller. No actual hardware is required for this example, except a laptop or desktop as your development environment. - Source: dev.to / about 1 year ago
  • When wouldn’t you use Python?
    Https://freertos.org/ for example is a popular OS, that has realtime capabilities and fits in 9KB of RAM. https://micropython.org is basically a µC OS too, understands Python 3 Syntax and works with 16KB of RAM already. It might appear more convoluted at first, but you can get it to be real-time too by following the same principles as in any RTOS (react to stuff by means of ISR, allocate memory only initially and...

  • Looking for Resources to build a RTOS
    Just mentioning but, you can port FreeRTOS to your MCU and compiler and you are done. All thats left is tell the RTOS what to do. Ofc there is alot to learn about rtos. FreeRTOS. Source: about 2 years ago
