I do miss some fundamental information.
When looking up all the boards I have purchsed, I can not find uot wether to use the
MCU-pin number or the MCU pin aberrative name or the boards description pin name?
Which is correct?
Sorry confused.

What boards do you have.
If they are Arduino boards, you use the pin names/numbers printed on the PCB, not the controller IC pin numbers.
Reference ALL your pin allocations to the PCB data.
So

groundFungus:
Pin 7 is not a PWM pin.
Pin 7 is not an external interrupt pin.
A0 is not a PWM pin. It is a non PWM pin that can be set to be a digital input, digital output or analog input. 50% will cause an error.

What's smaller than a Feather but larger than a Trinket? It's an Adafruit ItsyBitsy M4 Express featuring the Microchip ATSAMD51! Small, powerful, with a ultra fast ATSAMD51 Cortex M4 processor running at 120 MHz - this microcontroller board is...

Thank's replying, but what I do wnant, is some of the attached picture.
which ones is the best I do not know.
But adafruit_products_pro5.png show at least pin-number to be used in programming? I think.
I do not dare to ask ARDINO or ADAFRUIT to create such pictures on all board.
I really do not.
