Welcome to the PCA9635-Arduino-Library wiki!

The PCA96350-Arduino-Library is a simple library for the NXP PCA9635 PWM 16 LED driver. It is being done as an experiment to explore how Arduino libraries are created. I plan to implement the methods digitalWrite and analogWrite. The PCA9635 chip is only available in surface mount, so I might also include a simple break out board design if you want also want to explore this chip.

I believe that the PCA9635 has been superseded by the PCA9685. I plan to write a library for this chip too. The PCA9685's oscillator can be controlled, so this might be useful for controlling servos and steppers.
