Hello, I was reading on the Kicad tutorial wiki page, and noticed something weird with the schamatic of the Teensy 2.0 dev board [1].

The i/o pins are in reverse order. Each label (PB0, PB1, etc) is associated with a pin number. And the schematic in the tutorial shows PB0 is associated with pin 28, but I think it should be pin 2.

Can someone please verify the correctness of the component? I really hope I got it all wrong!

@b1gtuna: The kicad component goes exactly in the opposite order (starts upper-right on the teensy, then clockwise), which makes sense because the teensy is normally mounted on the underside of the board, with its topside looking down.

@flabbergast, doh! that makes a lot of sense now. Thanks.

Seems like this is something I did.. I probably just made the numbering up as I went. As long as the numbering is the same on the schematics symbol as on the component footprint, I think it's really up to the designer to choose =) It may be backwards to the norm with pins numbered counter clockwise (positive direction mathematically, I know and point this out all the time to others...). When I made this I was very new to electronics in every regard =D

The tutorial also looks like a broken version of something from the old GH or something that was never finished...

Hard to imagine there was a time when you were new to all these . I got around it by remapping the pins in the firmware. Works well!

Well, I'm still not very good at electronics in general... This digital matrix scanning thing is just very simple. My skill lies rather in routing out traces in KiCAD =)

Thanks for pioneering this for us!


Without access to the Phantom files and your help, I would have never been able to generate keyboard PCBs.
