int led = PH6+3;//this is equal to PH6 or D9?!?
why is it offset by 3? I should be able to use PH6 without the +3 in the arduino IDE. I am using a custom board but I have double checked that the pins are matching to where i want them to go. It would be way easier to use the PIN NAMES rather then arduino names.
Im using a ATMEGA2560 on my custom board.

I'm using bare-metal avr instead of arduino but PH6 is propably a macro constant and this is equal to some constant + 3. Did you copy/paste this code or whats the problem? There is no macro for pin that you want to use?

Its more I want to be able to accurately use the pins by what the Atmel datasheet calls them. So somewhere there is a header file I need to find and fix the Macro Constants?

I think you are using this macros wrong and there is a macro for your pin. What pin do you want to use?

@user2175468 No, avr io definitons are consistent as it's just bit position in a Byte. If you want something more consistent, you can make your own core (if it doesn't exist already) with better mapping. You can take a look on MightyCore or MegaCore, there are several layouts mappings

You can, but you should use direct port manipulation instead of arduino super slow wrappers
