Quote I would be interested to see any instances where pins had to be mapped one way because another wouldn't work that couldn't be sorted in the design/layup stage... guys?

Every commercially produced motherboard and shield requires different pin allocations. Many of these allow complete applications to be built on cheap plug-and-play H/W - no soldering required.

so Raspberry have poisoned the whole gig with no-one knowing where they stand

Millions of ST and Microchip designs with no such uncertainties.

I do understand why pin-mapping is supported (and you give an excellent argument above), but I can't help but balk at changing the bed-rock of SETPIN - even without a default config.

we shall have to agree to disagree I think, either that or it's pistols at dawn

Not really true for ST - I have often "moved things around".

It strikes me as no big deal at all. YMMV.

Just about every current PIC and AVR has configurable pins. Only the early versions tie functions to particular pins. Whether we like it or not the concept is here to stay and is becoming more popular with every new chip. It has a lot of advantages over the fixed method when you are laying out a PCB, and the PicoMite, unlike the Maximite range, is intended to be PCB mounted for embedded control.

The PicoMite is a whole new MMBasic platform. There hasn't been anything like it before. It's given us the opportunity to try different approaches. You may not like some of the choices made, Cap'n, but that doesn't mean that they are either right or wrong. User pressure *might* eventually lead to fixed pin allocations or people might find that they like the current system. We don't know yet, it's not been around long enough.

Anyone can have their own fixed pin allocations. A block of setup code that you drop into all your programs. Perhaps as a subroutine.

Just adding to this thread so all Picomite documentation suggestions are in one place for easy reference.

As posted in another thread:
MM.INFO$(VERSION) is not listed in Picomite User Manual MMBasic Ver 5.07.01 Page 68-69 (although it works).
