Code size reduction (30478 of 30720 bytes)

Using Arduino Microcontrollers
20

Thank you everyone for looking over the code. I can verify that replacing all of the

const uint8_t bla = xx;

with

#define bla xx

retained the exact code size.

@westwf The font is pretty large, 8 bytes / char. Most symbols use only 7x7 pixels so I could save 128 bytes there. I had a quick look at the optiboot. Looks like the way to go.

Thanks again!
