使用SX1509QB和PIC32MZ2048EFH100实现轻松的外设连接和控制

/*!
 * @file main.c
 * @brief Expand9 Click example
 *
 * # Description
 * This is an example that demonstrates the use of the Expand 9 Click board™.
 * The library initializes and defines the I2C bus drivers 
 * to write and read data from registers. 
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * The initialization of I2C  module, log UART, and additional pins. 
 * After driver initialization the app set default settings.
 *
 * ## Application Task
 * This is an example that demonstrates the use of the Expand 9 Click board™.
 * This example shows the capabilities of the Expand 9 click by toggling each of 16 available channels.
 * Results are being sent to the Usart Terminal where you can track their changes.
