General Description

LED Matrix programmed via 1MHz I2C compatible interface.

Each LED can be dimmed individually with 8-bit PWM data, and each CSx has 8-bit DC scaling (Color Calibration) data which allowing 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, HTR3229 store the open or short information in Open-Short Registers.
