LSM6DSL Click

LSM6DSL 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 app measures linear and angular velocity with six degrees of freedom.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Lsm6Dsl

Example Key Functions

• lsm6dsl_cfg_setup Config Object Initialization function.

void lsm6dsl_cfg_setup ( lsm6dsl_cfg_t *cfg );

• lsm6dsl_init Initialization function.

err_t lsm6dsl_init ( lsm6dsl_t *ctx, lsm6dsl_cfg_t *cfg );

• lsm6dsl_default_cfg Click Default Configuration function.

void lsm6dsl_default_cfg ( lsm6dsl_t *ctx );

• lsm6dsl_set_accel_config This function set accel configuration to the target LSM6DSL_CTRL1_XL register of LSM6DSL sensor.

void lsm6dsl_set_accel_config ( lsm6dsl_t *ctx, uint8_t odr_sel, uint8_t full_scale );

• lsm6dsl_set_gyro_config This function set gyro configuration to the target LSM6DSL_CTRL1_XL register of LSM6DSL sensor.

void lsm6dsl_set_gyro_config ( lsm6dsl_t *ctx, uint8_t odr_sel, uint8_t full_scale );

• lsm6dsl_get_axis This function get axis value from the two target 8-bit register address of LSM6DSL sensor.

uint16_t lsm6dsl_get_axis ( lsm6dsl_t *ctx, uint8_t reg_address_low );

Application Init

Initialization driver.

void application_init ( void )
{
    log_cfg_t log_cfg;
    lsm6dsl_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 ----\r\n" );

    //  Click initialization.

    lsm6dsl_cfg_setup( &cfg );
    LSM6DSL_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    lsm6dsl_init( &lsm6dsl, &cfg );

    lsm6dsl_default_cfg( &lsm6dsl );

    log_printf( &logger, "---------------------------------------\r\n" );
    log_printf( &logger, "|            LSM6DSL Click            |\r\n" );
    log_printf( &logger, "---------------------------------------\r\n" );
    log_printf( &logger, "|     Accel       |       Gyro        |\r\n" );
    log_printf( &logger, "---------------------------------------\r\n" );

    Delay_ms ( 100 );
}

Application Task

This is a example which demonstrates the use of LSM6DSL Click board. LSM6DSL Click communicates with register via SPI by write to register and read from register, measured acceleration and gyroscope coordinates values ( X,Y,Z ) Result are being sent to the uart where you can track their changes. All data logs on usb uart for aproximetly every 3 sec.

void application_task ( void )
{

    lsm6dsl_get_accel( &lsm6dsl, &accel, LSM6DSL_FULLSCALE_XL_2 );
    
    Delay_ms ( 10 );
    
    lsm6dsl_get_gyro( &lsm6dsl, &gyro, LSM6DSL_FULLSCALE_G_245 );
    
    Delay_ms ( 10 );

    log_printf( &logger, " Accel X : %f |  Gyro X : %f |\r\n", accel.accel_x, gyro.gyro_x );

    log_printf( &logger, " Accel Y : %f |  Gyro Y : %f |\r\n", accel.accel_y, gyro.gyro_y );

    log_printf( &logger, " Accel Z : %f |  Gyro Z : %f |\r\n", accel.accel_z, gyro.gyro_z );

    log_printf( &logger, "---------------------------------------\r\n" );

    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    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.
