使用TPS25750S和STM32G431RB确保更快、更安全、更多功能的设备充电

/*!
 * @file main.c
 * @brief USB-C Power Click example
 *
 * # Description
 * This example demonstrates the use of the USB-C Power Click board™
 * by configuring the PD controller to attempt to become a Power Source.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * The initialization of I2C module, log UART, and additional pins.
 * After the driver init, the app executes a default configuration,
 * depending on PD Device Mode, the app performs the patch bundle update tasks
 * for loading a patch bundle in burst mode to the PD controller.
 *
 * ## Application Task
 * The application display status information about 
 * the PD controller data role and power of the connection.
 * Results are being sent to the UART Terminal, where you can track their changes.
 * 
 * ## Additional Function
 * - static void usbcpower_display_status ( void )
 * - static void usbcpower_display_pwr_status ( void )
 *
 * @note
 * For the advanced configuration, use the TPS25750 Application Customization Tool:
 * https://dev.ti.com/gallery/search/TPS25750_Application_Customization_Tool
