LSM303AGR Click

LSM303AGR Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.

Example Description

This demo example returns magnetic and acceleration values from the LSM303AGR sensor.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.LSM303AGR

Example Key Functions

• lsm303agr_cfg_setup Config Object Initialization function.

void lsm303agr_cfg_setup ( lsm303agr_cfg_t *cfg );

• lsm303agr_init Initialization function.

err_t lsm303agr_init ( lsm303agr_t *ctx, lsm303agr_cfg_t *cfg );

• lsm303agr_default_cfg Click Default Configuration function.

void lsm303agr_default_cfg ( lsm303agr_t *ctx );

• lsm303agr_get_acc_axis_x Reading the raw X axis data and calculating the value.

float lsm303agr_get_acc_axis_x ( lsm303agr_t *ctx );

• lsm303agr_get_mag_axis_x Reading the raw X axis data and calculating the value.

float lsm303agr_get_mag_axis_x ( lsm303agr_t *ctx );

• lsm303agr_get_mag_axis_y Reading the raw Y axis data and calculating the value.

float lsm303agr_get_mag_axis_y ( lsm303agr_t *ctx );

Application Init

Driver initialization and setting operating modes of accelerometer and magnetometer.

void application_init ( void )
{
    log_cfg_t log_cfg;
    lsm303agr_cfg_t cfg;

    /** 
     * 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.

    lsm303agr_cfg_setup( &cfg );
    LSM303AGR_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    lsm303agr_init( &lsm303agr, &cfg );
    lsm303agr_default_cfg ( &lsm303agr );
   
}

Application Task

Reading accelerometer and magnetometer axis X,Y,Z and displaying it on terminal.

void application_task ( void )
{
    //  Task implementation.

    log_printf(&logger, "======== Accelerometer data ========\r\n");
    
    read_data = lsm303agr_get_acc_axis_x ( &lsm303agr );
    log_printf(&logger, "X Axis : %f\r\n", read_data);

    read_data = lsm303agr_get_acc_axis_y ( &lsm303agr );
    log_printf(&logger, "Y Axis : %f\r\n", read_data);

    read_data = lsm303agr_get_acc_axis_z ( &lsm303agr );
    log_printf(&logger, "Z Axis : %f\r\n", read_data);
    
    log_printf(&logger, "======== Mangetometer data ========\r\n");
    
    read_data = lsm303agr_get_mag_axis_x ( &lsm303agr );
    log_printf(&logger, "X Axis : %f\r\n", read_data);

    read_data = lsm303agr_get_mag_axis_y ( &lsm303agr );
    log_printf(&logger, "Y Axis : %f\r\n", read_data);

    read_data = lsm303agr_get_mag_axis_z ( &lsm303agr );
    log_printf(&logger, "Z Axis : %f\r\n", read_data);

    Delay_ms ( 1000 );
}

Application Output

This Click board can be interfaced and monitored in two ways:

• Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
• UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
