WarmCat 6 digit x 14 segment Backpack
Library and example code for the 6x14 segment i2c (HT16K33) modular display backpack.
This backpack consists of a 6-digit alphanumeric display, driven by the HT16K33. Connection to the Arduino is simple, with just two wires (SDA & SCL), in addition to power and ground. A separate pin "Vi2c" is provided should you wish to drive the logic at a different voltage to the display; for most uses this can just be linked with VDD.
Up to 8 of these backpacks can be daisychained by soldering the address jumpers.
