defining board type

[ithinkido]

What would be the correct way to define the LGT8F 328P board type similar to how this would work for an AVR 328P ?

eg.

#ifdef __AVR_ATmega328P__

Perfect ! Thank you for the link.

Is it possible that there is some sort of overlap between the (AVR) and (LGT8FX8P) board defnitions. I am getting false positives when using ifdef statements to seperate code for the oard types.

An example of code to demonstrate the false positives would be the following :

#ifdef __AVR__
#error AVR 
#endif

#ifdef __LGT8FX8P__
#error LGT
#endif



void setup() {
  // put your setup code here, to run once:

}

void loop() {
  // put your main code here, to run repeatedly:

}

Is there something I could do better to use the board definitions to separate code out dependent on the board type?

IIRC, it's normal __AVR__ is also defined on LGT board, because LGT boards are also AVR architecture.

I think you should test that way instead :

#ifdef __LGT8F__
#error LGT board
#else
#error Non LGT board
#endif

A bit confusing, but in the end, if it works, it works. Thank you for the answer
