Grid Eye Click

Grid-Eye 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 : MikroE Team
• Date : May 2020.
• Type : I2C type

Software Support

Example Description

64 individual thermal sensors build an image on a display. The detecting distance is 5m.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Grideye

Example Key Functions

• grideye_cfg_setup Config Object Initialization function.

void grideye_cfg_setup ( grideye_cfg_t *cfg );

• grideye_init Initialization function.

err_t grideye_init ( grideye_t *ctx, grideye_cfg_t *cfg );

• grideye_default_cfg Click Default Configuration function.

void grideye_default_cfg ( grideye_t *ctx );

• grideye_generic_write Generic write function.

void grideye_generic_write ( grideye_t *ctx, uint8_t reg, uint8_t *data_buf, uint8_t len );

• grideye_generic_read Generic read function.

void grideye_generic_read ( grideye_t *ctx,  uint8_t reg, uint8_t *data_buf, uint8_t len );

• grideye_write_data Write data function.

void grideye_write_data ( grideye_t *ctx, uint8_t wr_addr, uint16_t wr_data );

Application Init

Initalizes I2C driver, applies default settings, and makes an initial log.

void application_init ( void )
{
    log_cfg_t log_cfg;
    grideye_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 ----" );

    grideye_cfg_setup( &cfg );
    
    GRIDEYE_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    grideye_init( &grideye, &cfg );

    grideye_default_cfg ( &grideye );
}

Application Task

This example demonstrates the use of Grid-EYE Click board by reading full grid and displaying values via USART terminal.

void application_task ( void )
{
    uint8_t i;
    uint8_t j;
    uint16_t grid_array[ 64 ];
    uint16_t grid_array_tmp;

    grideye_read_grid( &grideye, &grid_array );

    for( i = 1; i < 9; i++ )
    {
        for( j = 1; j < 9; j++ )
        {
            log_printf( &logger, "| " );
            grid_array_tmp = grid_array[ i * j ];
            
            log_printf( &logger, "%d ", grid_array_tmp );
        }
        log_printf( &logger, " \r\n" );
        log_printf( &logger, "-------------------------------------- \r\n" );
    }
    Delay_ms ( 1000 );
}

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.
