使用 TPAFE0808 和 STM32F446RE 实现多通道信号控制与系统监测

 * @file main.c
 * @brief ADAC 4 Click example
 *
 * # Description
 * This example demonstrates the use of the ADAC 4 Click board which features 
 * an 8-channel, 12-bit DAC and ADC. The application configures each DAC channel 
 * with incremental values and measures the corresponding output voltage using 
 * the integrated ADC, as well as logs the device die temperature.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the logger and the Click board driver, and applies the default configuration.
 *
 * ## Application Task
 * Iterates through all 8 DAC/ADC channels, sets an output voltage, reads back the 
 * corresponding ADC voltage, and logs both values. Also reads and logs the die temperature.
