ET6038
General Description
ET6038 is a with 36 independent constant current low resistance LED drive output channels, each channel has 256 steps PWM regulation function, the chip also has 16 steps global current regulation function, the maximum driving current of 42.6mA.
ET6038 using I2C bus structure, with a separate address and continuous address writing function, through the code to configure a variety of register Settings, to achieve the setting of various parameters.
