Overview
This repository provides an I2C driver for the IS31FL3197 chip, which is used to control LEDs on hardware like the Arduino GIGA Display Shield. It offers flexible LED control interfaces and supports low-power operation, making it suitable for embedded projects requiring visual feedback.
Key Features
- Individual LED Control — Direct manipulation of each LED's intensity, PWM, and current boost.
- Color Interface — Grouped control of all LEDs using RGB color tuples.
- Pattern Interface — Programmable color sequences with configurable timing, gamma correction, and loop options.
- Multiple Operation Modes — Supports PWM & Current Source, Pattern, and Current Source modes per LED.
- Power Efficiency — Patterns can run during MCU deep sleep, enabling low-power user feedback.
Philosophy
The driver is designed to provide intuitive, humanized control over the IS31FL3197's capabilities while maintaining flexibility for advanced embedded use cases.
