SparkFun RGB Sensor - BH1749NUC (SPX-14733)
The PCA9536 is a 4-bit I/O digital expander, which communicates via an I2C bus. The expander can read or write four separate I/O. This IC is used on the SparkX RGB breakout to turn on/off the various RGBW LEDs to illuminate the object under test.
This library handles the initialization of the PCA9536 and supports standard pinMode, digitalRead, and digitalWrite functions.
