Piezo Accel 2 Click - 25g is a compact add-on board for precise vibration and motion monitoring in condition-based maintenance applications. This board features the 830M1-0025, a triaxial piezoelectric accelerometer from TE Connectivity, capable of detecting motion and acceleration along all three axes (X, Y, Z). The 830M1-0025 offers a ±25g range with a sensitivity of 50mV/g, providing reliable and accurate analog voltage outputs. It integrates a built-in RTD temperature sensor for simultaneous vibration and temperature monitoring, and the onboard MCP3562R 24-bit ADC converts these signals into high-resolution digital data. Communication is made through an SPI interface with additional interrupt and clock functionality for easy integration with a host MCU.

We provide a library for the Piezo Accel 2 25g Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.
Package can be downloaded/installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.
This library contains API for Piezo Accel 2 25g Click driver.
piezoaccel225g_cfg_setup Config Object Initialization function.
void piezoaccel225g_cfg_setup ( piezoaccel225g_cfg_t *cfg );piezoaccel225g_init Initialization function.

err_t piezoaccel225g_fast_cmd_write ( piezoaccel225g_t *ctx, uint8_t fast_cmd );piezoaccel225g_reg_read_multi This function reads a desired number of data bytes starting from the selected register by using SPI serial interface.
err_t piezoaccel225g_reg_read_multi ( piezoaccel225g_t *ctx, uint8_t reg, uint8_t *data_out, uint8_t len );This example demonstrates the use of Piezo Accel 2 25g Click board by reading and displaying the ADC values of X, Y, and Z axis, and the internal temperature sensor measurements. Those data can be visualized on the SerialPlot application.
The demo application is composed of two sections :
Initializes the driver and performs the Click default configuration for ADC measurements.
void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    piezoaccel225g_cfg_t piezoaccel225g_cfg;  /**< Click config object. */
    /** 
     * Logger initialization.
     * Default baud rate: 115200
     * Default log level: LOG_LEVEL_DEBUG
     * @note If USB_UART_RX and USB_UART_TX 
     * are defined as HAL_PIN_NC, you will 
     * need to define them manually for log to work. 
     * See @b LOG_MAP_USB_UART macro definition for detailed explanation.
     */
    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, " Application Init " );
    // Click initialization.
    piezoaccel225g_cfg_setup( &piezoaccel225g_cfg );
    PIEZOACCEL225G_MAP_MIKROBUS( piezoaccel225g_cfg, MIKROBUS_1 );
    if ( SPI_MASTER_ERROR == piezoaccel225g_init( &piezoaccel225g, &piezoaccel225g_cfg ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    if ( PIEZOACCEL225G_ERROR == piezoaccel225g_default_cfg ( &piezoaccel225g ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }
    log_info( &logger, " Application Task " );
}
Reads the ADC values of X, Y, and Z axis, and the internal temperature sensor measurements and displays them on the USB UART (SerialPlot) every 5ms approximately.
void application_task ( void )
{
    piezoaccel225g_adc_data_t adc_data;
    if ( PIEZOACCEL225G_OK == piezoaccel225g_read_adc_data ( &piezoaccel225g, &adc_data ) )
    {
        log_printf ( &logger, "%lu;%lu;%lu;%lu;\r\n", adc_data.raw_x, adc_data.raw_y, 
                                                      adc_data.raw_z, adc_data.raw_temp );
    }
}We recommend using the SerialPlot tool for data visualization. The temperature measurements should be visualized independently. The data format for plotter is as follows: X;Y;Z;TEMP;
The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Additional notes and informations
Depending on the development board you are using, you may need USB UART Click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. UART terminal is available in all MikroElektronika compilers.
