Lumissil IS31FL3729 Matrix LED Drivers

Lumissil IS31FL3729 Matrix LED Drivers are general-purpose 16×8, or 15×9 LED Matrix programmable via a 1MHz I²C compatible interface. The LEDs can be individually dimmed, and each CSx has 8-bit DC scaling (color calibration) data. This allows 256 steps of linear PWM dimming for each dot and 256 steps of DC current adjustable level for each CSx. Additionally, each LED open and short state can be detected. The IS31FL3729 stores the open or short information in Open-Short Registers.
