Click library

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

Software Support

We provide a library for the TiltNshake 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 TiltNshake Click driver.

Standard key functions :

  • tiltnshake_cfg_setup Config Object Initialization function.

    void tiltnshake_cfg_setup ( tiltnshake_cfg_t *cfg ); 
  • tiltnshake_init Initialization function.

    err_t tiltnshake_init ( tiltnshake_t *ctx, tiltnshake_cfg_t *cfg );

Example key functions :

  • tiltnshake_read_status_and_axis Function for read status and axis

    void tiltnshake_read_status_and_axis ( tiltnshake_t *ctx, uint8_t *status, float *out_x, float *out_y, float *out_z )
  • tiltnshake_enable Function for enabling chip

    void tiltnshake_enable ( tiltnshake_t *ctx );
  • tiltnshake_disable Function for disabling chip

    void tiltnshake_disable ( tiltnshake_t *ctx );

Example Description

This application is multifunctional 3-axis digital accelerometer that can also be configured as a 45-degree Tilt sensor.

The demo application is composed of two sections :

Application Init

Initializes device.


void application_init ( void )
{
    log_cfg_t log_cfg;
    tiltnshake_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.
    tiltnshake_cfg_setup( &cfg );
    TILTNSHAKE_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    tiltnshake_init( &tiltnshake, &cfg );

    log_info( &logger, " Application Task " );
}

Application Task

Reads 3-axis accelerometer measurement and logs results on the USB UART.

void application_task ( )
{
    uint8_t status = 0;
    float out_x = 0;
    float out_y = 0;
    float out_z = 0;

    tiltnshake_enable( &tiltnshake );
    tiltnshake_read_status_and_axis( &tiltnshake, &status, &out_x, &out_y, &out_z );
    tiltnshake_disable( &tiltnshake );

    if ( TILTNSHAKE_DATA_READY == status )
    {
        log_printf( &logger, " X: %.2f\r\n", out_x );
        log_printf( &logger, " Y: %.2f\r\n", out_y );
        log_printf( &logger, " Z: %.2f\r\n", out_z );
        log_printf( &logger, "----------\r\n");
        Delay_ms ( 500 );
    }
    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.TiltNshake

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.
