使用TC78B042FTG和PIC18F4682优化BLDC控制

/*!
 * @file main.c
 * @brief Brushless8 Click example
 *
 * # Description
 * This example showcases how to initialize and use the Brushless 8 Click. 
 * This application is a schowcase of controlling speed 
 * and direction of brushless motor with hall sesnor.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init 
 * Initializes the Click board to appropriate settings based on selected mode.
 * Initialization settings are sent through I2C bus and the motor itself is
 * controlled via PWM or DAC over I2C.
 * Modes:
 *     - BRUSHLESS8_PWM
 *     - BRUSHLESS8_DAC
 *
 * ## Application Task  
 * This example demonstrates the use of Brushless 8 Click board.
 * Brushless 8 Click communicates with the device via I2C driver in order to 
 * set adequate voltage level for connected motor.
 * Current PWM/DAC settings being output are sent via logger.
 * Results are being sent to the Usart Terminal where you can track their changes.
 * 
 * @note Take into consideration that the jumper on Brushless 8 Click board
 * has to be set adequately for selected mode ( @b VSPSEL ).
