使用BMA490L和PIC18F2620迈入运动感应的未来

/*!
 * @file main.c
 * @brief Accel15 Click example
 *
 * # Description
 * This library contains API for Accel 15 Click driver.
 * The library initializes and defines the I2C or SPI bus drivers 
 * to write and read data from registers. 
 * The library also includes a function for reading X-axis, Y-axis, and Z-axis data. 
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * The initialization of I2C or SPI module, log UART, and additional pins. 
 * After the driver init, the app checks communication, 
 * sensor ID, and then executes a default configuration.
 *
 * ## Application Task
 * Measures and displays acceleration data for X-axis, Y-axis, and Z-axis. 
 * Results are being sent to the USART terminal where the user can track their changes. 
 * This task repeats at data output rate which is set to 12.5 Hz.
