Arduino library for IS31FL3729 LED Matrix from Lumissil Microsystems.
The IS31FL3729 is a general purpose 16×8 (or 15×9) matrix LED driver programmed via an I2C bus interface. Each LED can be dimmed individually with 8-bit PWM data, and each current sink has 8-bit DC current scaling for color calibration. The combination enables 256 steps of linear PWM dimming for each dot and 256 steps of DC current adjustment for each current sink.
IS31FL3729 Features:
- Supply voltage range: 2.7V to 5.5V
