PCA9685 I2C PWM controller
Overview
This test appliation demonstrates the usage of the PCA9685 driver interface and can be used to test each PCA9685 PWM device with shell commands.
The application bases on the test application for PWM peripheral drivers which is under following copyright:

Usage
To use the test application, compile it with
make -C tests/driver_pca9685 BOARD=...
Please check the default configuration parameters in
$(RIOTBASE)/drivers/pca9685/include/pca9685_params.h and adopt them
if necessary.
If the active LOW output enable pin /OE is used, the GPIO has to be defined as parameter, e.g.
CFLAGS="-DPCA9685_PARAM_INT_PIN=\(GPIO\(0,6\)\)" \
make -C tests/driver_pca9685 BOARD=...
