使用LTC8500和STM32F302VC释放PWM的全部潜力

 * \file 
 * \brief Pwm2 Click example
 * 
 * # Description
 * This application send the PWM signal in one or more outputs.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Configures the Click board and sets all PWM channels on the Click board to
 * 50% duty cycle with the phase shift enabled.
 * 
 * ## Application Task  
 * The first 10 PWM channels of PWM2 Click board are switched back and forth 
 * from 25% duty cycle to 75% duty cycle every 10 seconds.
