Speed Radar Click

Speed Radar 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.

Click Library

• Author : Nenad Filipovic
• Date : Jul 2023.
• Type : UART type

Software Support

Example Description

This example demonstrates the use of Speed Radar Click board by processing the incoming data and displaying them on the USB UART.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.SpeedRadar

Example Key Functions

• speedradar_cfg_setup Config Object Initialization function.

void speedradar_cfg_setup ( speedradar_cfg_t *cfg );

• speedradar_init Initialization function.

err_t speedradar_init ( speedradar_t *ctx, speedradar_cfg_t *cfg );

• speedradar_default_cfg Click Default Configuration function.

err_t speedradar_default_cfg ( speedradar_t *ctx );

• speedradar_send_command Speed Radar send command function.

err_t speedradar_send_command ( speedradar_t *ctx, uint8_t *cmd )

• speedradar_get_direction Speed Radar get direction function.

uint8_t speedradar_get_direction ( speedradar_t *ctx )

• speedradar_get_detection Speed Radar get detection function.

uint8_t speedradar_get_detection ( speedradar_t *ctx );

Application Init

Initializes the driver and performs the Click default configuration.

void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    speedradar_cfg_t speedradar_cfg;  /**< Click config object. */

    /** 
     * 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.
    speedradar_cfg_setup( &speedradar_cfg );
    SPEEDRADAR_MAP_MIKROBUS( speedradar_cfg, MIKROBUS_1 );
    if ( UART_ERROR == speedradar_init( &speedradar, &speedradar_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    if ( SPEEDRADAR_ERROR == speedradar_default_cfg ( &speedradar ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }
    
    speedradar_process( &speedradar );
    speedradar_clear_app_buf( );
    Delay_ms ( 100 );
    log_info( &logger, " Application Task " );
    log_printf( &logger, " ---------------------- \r\n" );
    Delay_ms ( 100 );
}

Application Task

The demo application sends a command that returns and displays the speed [km/h] and magnitude [dB] of the dominant movement for the forward and backward planes of the spectrum, measured frontal to the sensor. Results are being sent to the UART Terminal, where you can track their changes.

void application_task ( void ) 
{
    speedradar_send_command( &speedradar, SPEEDRADAR_CMD_GET_DETECTION_STR );
    Delay_ms ( 50 );
    speedradar_process( &speedradar );
    if ( app_buf_len >= PROCESS_C00_RSP_LEN  )
    {
        speedradar_adv_det_display( );
        speedradar_clear_app_buf( );
        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.
