In another topic a discussion arised about the UNO R4 and the capacity of integer.
Looking into the IDE board select doesn't provide UNO R4, only Arduino UNO.
Which board to select to make 32 bit integer, not 16 bit as for the UNO R3?
Which version of the IDE do you have and have you installed the R4 boards ?
I suspect it's an "old" version. Where do I find that information in my "old" IDE?
It's about this topic.
The general problem is not really R4 related. It's for every board/processor that is not supported by the IDE out of the box. The core programs and compiler for all these boards must be installed via the boards manager, as already pointed out. Then you can select the new board via the tools->board menue. That's the same for IDE 1.x or IDE 2.x
And if the new board contains a 32-bit MCU, you will get 32-bit integer.
[Edit] It may even be necessary to add a boards manager URL under File->preferences, if the board is not supported by Arduino itself.
I take my hat off. Thank You for clearifying those things.
The end result surpriced a lot. Working in PDP-, Digitals computers as well as IBM360 int was always 16 bit as I met it.
But, but the world changes, develops..
