Hello
Thanks to you, I've changed (not all yet) some 'Int' to 'uint8_t'... result... my sketch length on Mega 2560:
Before was ~133000 bytes
Now is ~113000 bytes!!!
Amazing!
Finishing the changes, my next step will be apply 'Progmem' to manipulate my string arrays to LCD.
Thanks once again by your help!
Best regards
Pedro Ferrer
