使用TPL0501和PIC18F57Q43解锁电阻设置的新灵活性

 * @file main.c
 * @brief DigiPot2 Click example
 *
 * # Description
 * The demo application changes the resistance using DIGI POT 2 Click.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes SPI and LOG modules.
 *
 * ## Application Task
 * This is an example which demonstrates the use of DIGI POT 2 Click board.
 * Increments the wiper position by 10 positions every 5 seconds.
