* @brief Initialize the PCA9685 PWM device
*
* The function initializes the PWM device with the given parameters that are
* used for all channels. After calling this funcion, the PWM device is
* used for all channels. After calling this function, the PWM device is
* operational (powered on). That is, all outputs are active with the given
* parameters and the same duty cycle value as before the call.
*
* @note
* - PCA9685 works with internally with a resolution of 12 bit = 4096.
* Using a resolution that is not a power of two, will cause inaccuracy due
* to aligment errors when scaling down the internal resolution to the
* to alignment errors when scaling down the internal resolution to the
* configured resolution.
* - Frequencies from 24 Hz to 1526 Hz can be used with PCF9865.
