使用IR2104S和PIC18F57Q43开发高功率电机控制系统

/*!
 * @file main.c
 * @brief Driver2 Click example
 *
 * # Description
 * This is an example that demonstrates the use of the Driver 2 Click board.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes driver module and sets PWM.
 *
 * ## Application Task
 * Start motor example with change in motor speed using changes in PWM duty cycle.
