When you get to chips that arduino doesn't make an 'offical' board for (644P/1284P,etc) then your chart is going to be the reflection of just one persons or one companies decision on what 'arduino' abstracted pin number to use with which port/pins on the AVR chip in question. As a minimum your chart should state who's pins\_arduino.h file was used in the rendition of the pin outs. Otherwise there could be lots of confusion for some users of these 'non-standard-arduino' AVR chips Lefty ---

The solution is to create an editable PDF. I'm working on. ---

Ok, this is a editable version: [PinOut ATMega1284p - Editable Version](http://www.pighixxx.com/pgdev/Temp/atmega1284p_edit.pdf) If you like it, I can do a editable version for all processors. 😰 ---

I wasn't even a member of this forum, just a constant lurker. I had to register just so I could say THANK YOU and amazing work. This will be incredibly useful for someone with such a shoddy memory as I. 🙂 ---

First of all, great fucking job mate ! However I'm a bit confused now. As far as I know analog pin A01 is equivalent of (or you can set it as a) digital pin 14 and A02 is pin 15 and so on, but if I read your legend Gray colour means "digital pins" then I look at the pinout and gray colour says PCINT8. What Am I doing wrong. ---

I think it would be good to have a website for these in an easy laid out single website rather than searching down forum threads. ---
