识别和优化带有PAC1944和PIC18F57Q43的设备中的能量使用

/*!
 * @file main.c
 * @brief PAC1944 Click example
 *
 * # Description
 * This demo application shows an example of measuring voltage,
 * current and power in a selected part of the circuit. Note that
 * PAC1944 is a high side power monitor, therefore the desired
 * channel should be connected accordingly.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialization of I2C module, log UART and additional pins.
 * In addition, a default configuration is performed as followed:
 * Sample mode is 1024, adaptive accumulation;
 * INT pin is set as an alert;
 * SLW pin is set as slow sampling rate control;
 * All channels are on;
 * Channel 1 is set for bipolar measurements;
 * Channel 2 is set for bipolar measurements reduced by half;
 * Channel 3 and 4 are set for unipolar measurements.
 *
 * ## Application Task
 * The application sends a refresh command which stores the
 * measurement data in registers. Measurements are acquired
 * for voltage, current and power on channel 1 of PAC1944
 * click board. The last 8 measurements are averaged and
 * calculated in bipolar mode. Process is repeated every
 * two seconds.
