DESCRIPTION:

  • Implement C version of PCA9685 PWM Servo Controller with a client library and example binary which lets you set PWM values for all or a single servo

TESTING:

  • Able to move servos with the controller
# idle
./pca9685-servo-controller -f 50 0 0

# high value
./pca9685-servo-controller -f 50 0 900 500

# low value
./pca9685-servo-controller -f 50 0 600 500
QNXE-716

# all servos
./pca9685-servo-controller -f 50 1000 500
