LightRanger 2 Click

LightRanger 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.

Example Description

This example measures the distance of the object from the sensor.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.LightRanger2

Example Key Functions

• lightranger2_cfg_setup Config Object Initialization function.

void lightranger2_cfg_setup ( lightranger2_cfg_t *cfg );

• lightranger2_init Initialization function.

err_t lightranger2_init ( lightranger2_t *ctx, lightranger2_cfg_t *cfg );

• lightranger2_default_cfg Click Default Configuration function.

void lightranger2_default_cfg ( lightranger2_t *ctx );

• lightranger2_write_byte This function writes a byte of data to the targeted 8-bit register board.

void lightranger2_write_byte ( lightranger2_t* ctx, uint8_t reg_address, uint8_t write_data );

• lightranger2_read_bytes Function read a sequential data starting from the targeted 8-bit register.

void lightranger2_read_bytes ( lightranger2_t* ctx, uint8_t reg_address, uint8_t* read_data, uint8_t n_bytes );

• lightranger2_get_range_continuous Function gets a range measurement in millimeters when continuous mode is active.

uint16_t lightranger2_get_range_continuous ( lightranger2_t* ctx );

Application Init

Initialization driver,enable Vl6180X sensor and sets default configuration for Vl6180X.

void application_init ( void )
{
    log_cfg_t log_cfg;
    lightranger2_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.

    lightranger2_cfg_setup( &cfg );
    LIGHTRANGER2_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    lightranger2_init( &lightranger2, &cfg );
    lightranger2_default_cfg( &lightranger2 );
    
    lightranger2_start_continuous( &lightranger2, 0 );
    Delay_ms ( 100 );
}

Application Task

Measures the distance of the object from the sensor and logs on terminal.

void application_task ( void )
{
    uint16_t distance;
    
    distance = lightranger2_get_range_continuous( &lightranger2 );
    Delay_ms ( 10 );
    
    if ( distance )
    {
        log_printf( &logger, "Distance: %u mm \r\n", distance );
        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.
