使用LTC3110和PIC18F26K20实现能量优化

/*!
 * @file main.c
 * @brief UPS 3 Click Example.
 *
 * # Description
 * This application demonstrates the use of UPS 3 Click board. 
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialization driver enable's - GPIO, also write log.
 *
 * ## Application Task
 * With this example we show the operation of UPS 3 Clicks.
 * This example shows an autonomously transition from charge to backup mode.
 * Results are being sent to the Usart Terminal where you can track their changes.
