Big leds / sorry

Archiver

Hi Mitch

No I have one MAX per 256 LEDS, giving you the option of 1/2/4 LEDs /
Dot (the LEDs come on together within the DOT) - The dot space is
about 1" per block of 4 giving you a 8 x 8 array covering about 8"
square


Cheers
Chris

Is this 1/2/4 LED/dot option under software control? What is the most
significant effect of going from 1 -> 2 -> 4 LEDs / dot? Intensity?
