InetrfaceProducts NXP / PCA9632

This is a driver code for the PCA9632 is an I2C-bus controlled 4-bit LED driver optimized for Red/Green/Blue/Amber (RGBA) color mixing applications. In Individual brightness control mode, each LED output has its own 8-bit resolution (256 steps) fixed frequency Individual PWM controller that operates at 1.5625 kHz with a duty cycle that is adjustable from 0 % to 99.6 % to allow the LED to be set to a specific brightness value. This library including device class and "LedPwmOut class API" for ease of use.

The PCA9632 is an I²C-bus controlled 4-bit LED driver optimized for Red/Green/Blue/Amber (RGBA) color mixing applications.

High-level API is available

A high-level API that can be used as the "PwmOut" of bed-SDK is available.
This API enables to make instances of each LED output pins and control PWM duty cycle by assignment.
For detail information, refer API document of LedPwmOut Class class which is included in PCA962xA class library.
