Click library

  • Author : MikroE Team
  • Date : dec 2019.
  • Type : I2C/SPI type

Software Support

We provide a library for the Accel6 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 Accel6 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void accel6_cfg_setup ( accel6_cfg_t *cfg );

  • Initialization function.

    ACCEL6_RETVAL accel6_init ( accel6_t ctx, accel6_cfg_t cfg );

  • Click Default Configuration function.

    void accel6_default_cfg ( accel6_t *ctx, uint8_t range_data, uint8_t bw_data, uint8_t lpw_data );

Example key functions :

  • Functions for set offset

    void accel6_data_offset ( accel6_t ctx, uint8_t set_offset, float offset_data );

  • Functions for read orient

    void accel6_get_orient ( accel6_t ctx, uint8_t z_orient, uint8_t *xy_orient );

  • Functions for read axis data

    float accel6_get_axis ( accel6_t *ctx, uint8_t axis );

Examples Description

This application allows acceleration measurement in three perpendicular axes.

The demo application is composed of two sections :

Application Init

Initializes Driver init and settings accelerometer data range, bandwidth, mode and sleep timer which are necessary for the init chip.


void application_init ( void )
{
    log_cfg_t log_cfg;
    accel6_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.

    accel6_cfg_setup( &cfg );
    ACCEL6_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    accel6_init( &accel6, &cfg );

    accel6_soft_reset( &accel6 );
    Delay_1sec();
    log_info( &logger, "---- Device reset done ----" );

    accel6_default_cfg( &accel6, ACCEL6_PMU_RANGE_4g, 
                                          ACCEL6_PMU_BW_125Hz, 
                                          ACCEL6_PMU_LPW_NORMAL_MODE | 
                                          ACCEL6_PMU_LPW_SLEEP_10ms );

    log_info( &logger, "---- Device configuration done ----" );

    Delay_1sec();
}

Application Task

Reads the accel X / Y / Z axis data in mg, Temperature data in C, detects the orientation of the X,Y and Z axis and checking on which axis the tap is detected. All data logs on usb uart for every 500 ms.

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.
