使用TP4056和PIC32MZ2048EFH100焕发电池新生

 * @file main.c
 * @brief Charger3 Click example
 *
 * # Description
 * This example demonstrates the utilization of Charger 3 click.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * The application init sets up the UART LOG and I2C communication
 * drivers. The default configuration disables write protection
 * and sets the operation mode to charging.
 *
 * ## Application Task
 * Task consists of two operations. First, the desired battery
 * charging current is set by the user. Since setting the current
 * doesn't implicitly reveals the resistance, the value
 * of AD5175 digipot is directly read from the RDAC register,
 * calculated and displayed on the uart log.
 *
 * *note:*
 * While the resistance of the AD5175 can be directly set and read,
 * the total resistance value on the PROG pin should be accounted for
 * ( this means an additional 1kohm in series ) setting of the
 * battery charging current.
