Hello Everyone,
I'm a beginner learning mostly by trial and error and I'm really struggling to use a 7 segment LEd display. I've recently bought a adafruit HT16K33 7 segment in the hope of getting it to work as I have has success with I2C LCD displays.
I can't find a node to run the display but there is alot of info on the product page for the display and I was wondering how hard it would be to create a node for this display from this info?

> What's better than a single LED? Lots of LEDs! The matrices use a driver chip that does all the heavy lifting for you: They have a built in clock so they multiplex the display. They use constant-current drivers for ultra-bright, consistent color,...
any help would be appreciated.

Is there a node.js module for it? If so, then the NR node would just be a wrapper around the node.js module. Would save a lot of time and effort if so. Looks like Adafruit only has support for the 14 segment device, in NPM.
