LSM6DSL Click

LSM6DSL Click measures linear and angular velocity with six degrees of freedom. It carries the LSM6DSL high-performance 3-axis digital accelerometer and 3-axis digital gyroscope.

Click library

• Author : MikroE Team
• Date : Jan 2020.
• Type : SPI type

Software Support

We provide a library for the Lsm6Dsl 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 form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

This library contains API for Lsm6Dsl Click driver.

Standard key functions :

• Config Object Initialization function.

  void lsm6dsl_cfg_setup ( lsm6dsl_cfg_t *cfg );

• Initialization function.

  LSM6DSL_RETVAL lsm6dsl_init ( lsm6dsl_t ctx, lsm6dsl_cfg_t cfg );

• Click Default Configuration function.

  void lsm6dsl_default_cfg ( lsm6dsl_t *ctx );

Example key functions :

• 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 );

• 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 );

• 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 );

Examples Description

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

The demo application is composed of two sections :

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 );
} 

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Other mikroE Libraries used in the example:

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

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. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.
