This library provides a hardware driver for a variety of displays bases on the Holtek KT16K33 controller chip, including four-digit, seven-segment LEDs; four-digit, 14-segment LEDs; 8x8 and 16x8 monochrome matrix LEDs; and bi-colour 8x8 matrix LEDs. It also supports four-digit, 14-segment LEDs based on the VK16K33 controller from Freenove.
The library also supports generic seven-segment displays wired up to an HT16K33, which can drive up to eight these LEDs. The HT16K33 may be on a board of your own design, or on a third-part one, such as the Adafruit 16x8 LED Matrix Driver Backpack. LED units you can connect range from single digits up to combinations of multi-digit units.
Note Connect your HT16K33 column pins to each LED’s digit selection pin, and its row pins to the LED’s segement selection pins.
The library comprises a core driver for the HT16K33 and child classes for each of the currently supported display products: just load in the driver for the display your project features.
The library supports both CircuitPython and MicroPython applications running on a variety of MCU-based devices, including members of the the AdaFruit Feather family, Sparkfun Feather devices and the Raspberry Pi Pico.
Please see the the documentation section for details of the general and device-specific driver APIs:
You can now install the library using the Python Package Index.
You can view HT16K33 Python’s source code at GitHub.
