Info to build driver for HT16K33 LED Matrix Backpack

[eugenedakin]

Hello,

This is my first time posting on the forums and its good to be here!

Where can I find information on how to build my own driver to drive the Ht16K33 LED matrix backpack? I program with Xojo and have made many previous Raspberry Pi drivers for LEDs, IC's, etc. Most of the examples have libraries in other languages. Is there a datasheet for the matrix backpack so that I can program my own driver? I found the HT16K33 datasheet, and the small 1.2" 8x8 ultra bright Yellow-G datasheet, and unfortunately have not found the matrix backpack datasheet (http://adafru.it/1048).


Thanks for your helpful suggestions. :)

The tutorial for LED backpacks has the HT16K33 datasheet:

The chip itself is just an I2C device, and you can use our Arduino/Python libraries as working code references:

Thanks for your reply Mike.

I'll give it a go.

Warm regards.
