HT16k33 and common cathod LED displays
« on: May 20, 2017, 10:21:57 am »
Hello,

I recently bought some HT16K33 chip to drive a bunch of 7 segments display. I have around 122 LEDs to drive, so this chip seemed to be perfect for me.

However, I only found some common anode 7-segments and the chip needs common cathode.
Anybody have an idea on how I can adapt this HT16K33 chip to work with common anode or if another chip could drive all this LEDs ?

I had a really hard time finding all the 7 segments I needed and I am not willing to buy other one with correct configuration.

Thanks for the help.
