Motion 2 Click

Motion 2 Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.

Software Support

Example Description

This example demonstrates the use of Motion 2 Click boards.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Motion2

Example Key Functions

• motion2_cfg_setup Config Object Initialization function.

  void motion2_cfg_setup ( motion2_cfg_t *cfg );

• motion2_init Initialization function.

  motion2_return_value_t motion2_init ( motion2_t *ctx, motion2_cfg_t *cfg );

• motion2_enable Enable motion sensor function.

  void motion2_enable ( motion2_t *ctx, uint8_t state );

• motion2_detect_state Get detection state function.

  uint8_t motion2_detect_state ( motion2_t *ctx );

Application Init

Initializes the driver and enables the motion sensor.

void application_init ( void ) 
{
   
    log_cfg_t log_cfg;  
    motion2_cfg_t motion2_cfg;  

    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, "---- Application Init ----" );
 
    // Click initialization.
 
    motion2_cfg_setup( &motion2_cfg );
    MOTION2_MAP_MIKROBUS( motion2_cfg, MIKROBUS_1 );
    if ( motion2_init( &motion2, &motion2_cfg ) == DIGITAL_OUT_UNSUPPORTED_PIN ) {
       
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );
 
        for ( ; ; );
    }
    
    motion2_enable( &motion2, MOTION2_MODULE_ENABLE );
    Delay_ms ( 100 );
    log_printf( &logger, "The sensor is ready.\r\n" );
    log_printf( &logger, "-----------------------\r\n" );
}

Application Task

It checks if the sensor has detected movement and therefore displays the desired message on the USB UART.

void application_task ( void ) 
{  
    uint8_t int_status;
 
    int_status = motion2_detect_state( &motion2 );
 
    if ( int_status == MOTION2_DETECT_OBJECT ) {
        log_printf( &logger, "Motion detected!\r\n" );
        log_printf( &logger, "-----------------------\r\n" );
        while ( int_status == MOTION2_DETECT_OBJECT ) {
            int_status = motion2_detect_state( &motion2 );
        }
        log_printf( &logger, "The sensor is ready.\r\n" );
        log_printf( &logger, "-----------------------\r\n" );
        Delay_ms ( 100 );
    }
}

Application Output

This Click board can be interfaced and monitored in two ways:

• Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
• UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
