Accel 10 click

Accel 10 Click features an ultra-low power triaxial "femto" accelerometer sensor with embedded intelligence, labeled as the LIS2DW12TR. This Click board™ allows linear motion and gravitational force measurements in ranges of ±2 g, ±4 g, ±8, and ±16 g in three perpendicular axes.

Click library

• Author : Nenad Filipovic
• Date : Jan 2020.
• Type : I2C/SPI type

Software Support

We provide a library for the Accel10 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 Accel10 Click driver.

Standard key functions :

• Config Object Initialization function.

void accel10_cfg_setup ( accel10_cfg_t *cfg );

• Initialization function.

ACCEL10_RETVAL accel10_init ( accel10_t *ctx, accel10_cfg_t *cfg );

• Click Default Configuration function.

void accel10_default_cfg ( accel10_t *ctx );

Example key functions :

• Check data ready function.

uint8_t accel10_check_data_ready ( accel10_t *ctx );

• Read Accel data function.

void accel10_get_data ( accel10_t *ctx, accel10_data_t *p_accel_data );

• Read temperature function.

int8_t accel10_read_temperature ( accel10_t *ctx );

Examples Description

This example demonstrates the use of Accel 10 click board.

The demo application is composed of two sections :

Application Init

Initializes the driver and checks the communication by reading the device ID. After that, performs the click default configuration.

void application_init ( void )
{
    log_cfg_t log_cfg;
    accel10_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.

    accel10_cfg_setup( &cfg );
    ACCEL10_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    accel10_init( &accel10, &cfg );
    Delay_ms( 500 );
    
    log_printf( &logger, "---------------------\r\n" );
    log_printf( &logger, "    Accel 10 Click\r\n" );
    log_printf( &logger, "---------------------\r\n" );
    
    // Checking communication
    if ( accel10_check_id( &accel10 ) == ACCEL10_SUCCESS )
    {
        log_printf( &logger, "  Communication  OK\r\n" );
        log_printf( &logger, "---------------------\r\n" );
        Delay_ms( 100 );
    }
    else
    {
        log_printf( &logger, "  Communication ERROR\r\n" );
        log_printf( &logger, "  Reset the device\r\n" );
        log_printf( &logger, "---------------------\r\n" );
        for ( ; ; );
    }
    
    accel10_default_cfg ( &accel10 );
    log_printf( &logger, "  Default config.\r\n" );
    log_printf( &logger, "---------------------\r\n" );
    Delay_ms( 100 );
}
  

Application Task

Reads the accel values for X, Y, and Z axis and also reads the temperature in Celsius and displays the results on the USB UART each second.

void application_task ( void )
{
    if ( accel10_check_data_ready( &accel10 ) == ACCEL10_STATUS_DATA_READY )
    {
        accel10_get_data ( &accel10, &accel_data );
        Delay_ms( 10 );
        
        log_printf( &logger, "  Accel X :  %d\r\n", accel_data.x );
        log_printf( &logger, "  Accel Y :  %d\r\n", accel_data.y );
        log_printf( &logger, "  Accel Z :  %d\r\n", accel_data.z );
    
        temperature = accel10_read_temperature( &accel10 );
        Delay_ms( 10 );

        log_printf( &logger, " Temperature :  %d C\r\n", ( int16_t ) temperature );
        log_printf( &logger, "---------------------\r\n" );
        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.Accel10

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.
