使用A80604-1和PIC18F2682简化多LED的管理

/*!
 * @file main.c
 * @brief LEDDriver13 Click example
 *
 * # Description
 * This library contains API for LED Driver 13 Click driver.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and executes the Click default configuration which
 * starts the PWM module and sets the LEDs current to minimum.
 *
 * ## Application Task
 * This is an example that demonstrates the use of the LED Driver 13 Click board™.
 * The app controls the LEDs brightness by changing the PWM duty cycle.
 * The PWM duty cycle percentage will be logged on the USB UART.
