Pi Pico

I suggest that we immediately retire any references to the Pico version of RISC OS on the Pi, and pretend that it never existed, before things get really confusing…

Is the new Pico of any interest to Risc OS?

Maybe there is a way to make a new RISC OS Pico for the Raspberry Pi Pico that runs text mode Basic via the serial terminal only? Could be fun! Although the graphic modes could be a problem :(

RISC OS (in its current form) can’t run on Cortex-M series CPUs. Cortex-M only supports the Thumb instruction set, and there are some major differences in supervisor/interrupt modes & memory mapping.

Is the new Pico of any interest to Risc OS?

Yes, if one of the two BBC Basic interpreters written in C is compiled for it :)

Not RISC OS, but acorn and bbc basic related;

It’s only the Thumb instruction set.

It looks promising for the sort of things I have used the LPC1114 for – same instruction set; I use the IAR toolset under Wine on Ubuntu. I would imagine that IAR will target the Pico if they haven’t already.

For the same 5 USD for Pi Pico you now get an LPC845 board – this one has ADC + DAC + hardware state machine + debugger. Free IDE. IAR support also.

But I guess Pi Pico will still become more popular – because of its name.

If the regular Pi is anything to go by, it’ll also succeed due to a massive library of example projects, tutorials, and being supported for many years after its release date.
