 * @brief SolidSwitch 2 Click example
 *
 * # Description
 * This example demonstrates the use of SolidSwitch 2 Click board by controlling the output state.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the Click default configuration which maps outputs as follows:
 * OUT2   - IN0,
 * OUT3   - IN1,
 * OUT4-5 - PWM GEN,
 * OUT6-7 - PWM LED.
 *
 * ## Application Task
 * Changes the PWM GEN (max to min) and PWM LED (min to max) duty cycle and toggles the IN0 and IN1
 * pins every 250ms. The duty cycle values and INx toggle messages will be displayed on the USB UART.
