Let's imagine you have a real-time problem that you can solve with the Raspberry Pi hardware but you need something much faster than an Arduino. Is it possible to bypass the OS of a Raspberry Pi to have used some kind of bootloader like an Arduino, and run with the same structure in real-time as with Arduino (i.e. no time-sharing), but much faster?

    Have a look at Teensy 4.0, it'll be much easier to set up and program than a bare-metal RPi.

    What task do you actually want implemented?

    First, understanding the limits of what you can and what you can't do. I've tried myself with arduino, but for some applications I found it quite slow.

  • Yes, Anono is very slow, get a stm32 board which is 10 times faster then Anono. Anono just makes you stupid. You can let one Rpi coordinate multiple STMs. aliexpress.com/w/wholesale-stm32-arm.html – tlfong01 10 mins ago

That is very much the premise of Ultibo.

What is Ultibo?

Imagine if you could have the simplicity and freedom of Arduino with the power and features of a Raspberry Pi. With the ease of a microcontroller and the flexibility of a real computer, Ultibo gives you a platform for creating anything without the limitations of a traditional operating system.

If Ultibo is not what you want there are plenty of other bare-metal (no operating system) examples for the Raspberry Pi.
