digitalPinToInterrupt on ATTiny841

Hello,

On the following line you associate INT0 with PB2:

ATTinyCore/avr/variants/tinyx41_cw/pins_arduino.h

Line 94 in e5046a5

#define digitalPinToInterrupt(p) ((p) == PIN_PB2 ? 0 : NOT_AN_INTERRUPT)

But on the ATTiny841, INT0 is on PB1. Did I miss something ?

Thanks,

Nicolas

And just a few days agpo someone asked why this version wasn't in board manager. It's stuff like this!!! Was wrong on both directions of pin mapping for the the x41, because the files had been based on the 84, and because Atmel's designers had been sniffing glue or something, the INT0 pin which was PB2 on the 84, was moved to the strictly worse PB1 for the follow-on product.

Thanks for reporting. We need a ton more people doing that.

Thank you. Yes, strange to use one of the crystal pin for this interrupt...

Especially when the chip is a followon tp a chip that had it 9n a different pin. M9re than anything I think what doomed Atmel to being bought out was a lack of managers who were willing to walk the engineering floor wielding whips to keep the engineers in line, and keep that darned dartboard that they taped product package diagrams to in order to choose pinouts locked up.
