使用TB6575FNG和PIC18F45K50释放无刷电机的潜力

 * \brief Brushless Click example
 * 
 * # Description
 * This example showcases how to initialize and use the Brushless Click. 
 * The Click has a brushless motor driver which controls the work 
 * of the motor through the BLDC terminal. 
 * In order for this example to work a motor and a power supply are needed. 
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * This function initializes and configures the logger and Click modules.
 * 
 * ## Application Task  
 * This is an example that demonstrates the use of a Brushless Click board.
 * Brushless Click communicates with the register via the PWM interface.
 * It shows moving in the left direction from slow to fast speed
 * and from fast to slow speed.
 * Results are being sent to the Usart Terminal where you can track their changes.
