Arduino for STM32

I don't understand the difference completely,

Most common microcontrollers have more capabilities than can be utilized at one time because the physical standard sizes limit the number of physical pins. Chip architects and engineer decide how the default "pins" will be configured. Internal ...

Find the closest uC in your family:

for cmake, my guess is it could live 'outside' as a 'different' (experimental) core at least for a while, maybe as it progresses, it may evolve differently.


I you have a few minutes, I think you will find this interesting: Optimizing Arduino Code: no setup(), no loop()

When dealing with Windows 32/64 one can dig deeper than OS tools with specific utilities:

For example:

Portmon is a utility that monitors and displays all serial and parallel port activity on a system. It has advanced filtering and ...

i've a 'strange' feeling that we'd perhaps move to use more of 'cmake' or 'platform io' types of setups.
But that would break a lot of compatibility with 'Arduinoish' way of doing things.

Opinion: I have always thought of Arduino being an entry/intermittent approach to getting non ...

Most take the "closest board config with the same or same family uC" and do a copy, paste, edit.

ould I be better off going with a "Black Pill" that has more memory?

Yep: According to my Freshman year Prof 50 years ago, "... You can never have too much memory." (And he was talking about the Fortran system at the Uni.)

... I just scored 40 STM32f103C6 chips at a reasonable price (£1 each at least its reasonable in todays market) And the 32KB flash would be fine for many of my smaller projects that I might use a atmega328 for.

If you are just doing Arduino small projects that would have/could-be done with ...

Maybe. For me arduino is just a hardware abstraction layer + IDE which is much more pleasant to use (for me) than STs‘ own HAL + IDE


I think if carefully considered, it is a software (simplified commands, functions similar to BASIC ) and hardware is not abstracted but simplified into basic ...

So you used DMA in the Arduino Mega2560 board?


No.
My point was that the mechanics taking the majority of 750mS would be unchanged; therefore DMA would have only marginally affected the full loop{} time. Generally for non-graphic applications, the complexity of DMA is not justified, IMO ...
