Use textWrite's delay on smaller sizes with faster ARM processors #2

Closed PaulStoffregen closed 10 years ago

PaulStoffregen commented 10 years ago

On Arduino Uno, this delay is only needed for text sizes 2 and 3. Uno just isn't fast enough to send another SPI command before size 1 renders.

On Teensy 3.1 runs much faster, so this delay is needed to avoid garbled text.
