i tried to make demo board just as described in datasheet. when i turn it on led is working .... ok
now i try to make use of dimming pin. i connect dim pin to my avr microcontroler.
first i want to just turn led off. i read in documentation that when dim pin is low, HG drive is off.
so i set my avr to output 0 on this pin. i also added pull down resistor just in case.
--> led is still on
just in case i try to output 1 on this pin ...
what am i doing wrong ? shouldnt it work that way ? when DIM is low ... (connected to ground), led should be off ...
thank you for your help.
