nuttx VS parm_extended

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/

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.

You should definitely have a look at NuttX.

Maybe Nuttx can be an alternative. Have a look: https://nuttx.apache.org/

Zephyr, RIOT, NuttX are all open source RTOSes happy about contributions

Microcontrollers are a good start. Boards are cheap and sensors are plentiful. You could get a yet unsupported board and port RIOT, Zephyr or NuttX.

Shameless self-plug: I wrote a [blog post](https://zdimension.fr/crabs-all-the-way-down/) about this, where I talk about implementing an ARM CPU in logic circuits and running code in it

I do have a website! I wrote a lengthy blogpost about this project a few weeks back: https://zdimension.fr/crabs-all-the-way-down/

Crabs All the Way Down: Running Rust on Logic Gates I rarely read articles as wide and deep than this one. Tom Niget makes and simulates a CPU that supports most of the ARM Thumb instruction set. Then he jumps through many hoops to showcase several applications: a plotter, a BASIC interpreter/REPL, a webserver, a terminal emulator... Impressive! All the ARM/Thumb CPU and code is open source.
