使用TMCS1108A2U和PIC18LF45K42清晰查看交流或直流电流特性

 * @file main.c
 * @brief HallCurrent11 Click example
 *
 * # Description
 * This library contains API for Hall Current 11 Click driver.
 * The demo application reads ADC value and current ( A ).
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes I2C driver and log UART.
 * After driver initialization the app set default settings.
 *
 * ## Application Task
 * This is an example that demonstrates the use of the Hall Current 11 Click board™.
 * In this example, we read and display the ADC values and current ( A ) data.
 * Results are being sent to the Usart Terminal where you can track their changes.
