HT16K33

ht16k33-async is an async driver for the Holtek HT16K33 "RAM Mapping 16*8 LED Controller Driver with keyscan".

Currently, only the 28-pin SOP package type is supported.

Features

• Uses the embedded-hal-async hardware abstraction.
• Supports no_std for embedded devices.
• Supports all 20/24/28-pin SOP package types.
• Displays all 128 LEDs.
• Support dimming.
• Reads keyscan.
• Manages interrupts.

Examples

The examples are written using embassy for Raspberry Pi Pico. As the Pico is a 3.3V device, you will need to use an I2C level shifter like the TCA9517 to talk to the HT16K33.
