Library only works for Arduino Uno and others based on the ATmega328. The pins are hard coded into the library for better performance, only port D and the SPI Pins are used.

LAT / STB / LT -- Digital Pin 2
OE / EN --------- Digital Pin 3
LA / A ----------- Digital Pin 4
LB / B ----------- Digital Pin 5
LC / C ----------- Digital Pin 6
LD / D ----------- Digital Pin 7
R1 / R1 ----------- Digital Pin 11
CLK / SK --------- Digital Pin 13

The library increases the Timer2 frequency so that the PWM runs on 32 kHz. Affected are only the pins 3 and 11, both occupied by the interface.

Χρησιμοποιούμε Timer2 έτσι ώστε το PWM να λειτουργεί στα 32 kHz. Timer2 οι ακίδες 3 και 11.
