Accel 5 click

Accel 5 click features an ultra-low power triaxial accelerometer sensor, labeled as the BMA400. 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 : MikroE Team
• Date : dec 2019.
• Type : I2C type

Software Support

We provide a library for the Accel5 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 Accel5 Click driver.

Standard key functions :

• Config Object Initialization function.

void accel5_cfg_setup ( accel5_cfg_t *cfg );

• Initialization function.

ACCEL5_RETVAL accel5_init ( accel5_t *ctx, accel5_cfg_t *cfg );

• Click Default Configuration function.

void accel5_default_cfg ( accel5_t *ctx );

Example key functions :

• Functions for write one byte in register

void accel5_write_byte ( accel5_t *ctx, uint8_t reg, uint8_t reg_data );

• Functions for read byte from register.

uint8_t accel5_read_byte ( accel5_t *ctx, uint8_t reg );

• Functions for read data from register.

uint16_t accel5_read_data ( accel5_t *ctx, uint8_t reg );

Examples Description

This application allows linear motion and gravitational force measurements.

The demo application is composed of two sections :

Application Init

Initializes Driver init and settings accelerometer data range and mode.

void application_init ( void )
{
log_cfg_t log_cfg;
    accel5_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.

    accel5_cfg_setup( &cfg );
    ACCEL5_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    accel5_init( &accel5, &cfg );
}
  

Application Task

Reads the accel X / Y / Z axis data, every 500 ms.

void application_task ( void )
{
    x_axis_data = accel5_get_axis( &accel5, ACCEL5_X_AXIS );
    log_printf ( &logger, " X axis : %d \r\n  ", x_axis_data );
    
    y_axis_data = accel5_get_axis( &accel5, ACCEL5_Y_AXIS );
    log_printf ( &logger, " Y axis : %d \r\n  ", y_axis_data );

    z_axis_data = accel5_get_axis( &accel5, ACCEL5_Z_AXIS );
    log_printf ( &logger, " Z axis : %d \r\n  ", z_axis_data );
    
    Delay_ms( 500 );
}  

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.Accel5

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.
