README

pca9685

Yet another library for driving servos via a PCA9685 chip. These chips are used in many popular i2c-interface PWM controller boards compatible with the Arduino, Raspberry Pi, and other single board computers and microcontrollers. Clean and simple, uses gobot for backend. Includes a simple servo calibration tool. See ./examples.

Written in part because the gobot ServoDriver library only uses 8 bits of resolution, while the pca9685 chip supports 12 bits. This library uses all 12 bits.
