PCA9685 I2C PWM controller

Overview

This test application 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/drivers/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/drivers/pca9685 BOARD=...
