IR Grid 5 Click

IR Grid 5 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 demonstrates the use of the IR Grid 5 Click board by reading and displaying the sensor temperature as well as the object temperature image from the 32x24 pixel array.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.IRGrid5

Example Key Functions

• irgrid5_cfg_setup This function initializes Click configuration structure to initial values.

void irgrid5_cfg_setup ( irgrid5_cfg_t *cfg );

• irgrid5_init This function initializes all necessary pins and peripherals used for this Click board.

err_t irgrid5_init ( irgrid5_t *ctx, irgrid5_cfg_t *cfg );

• irgrid5_default_cfg This function executes a default configuration of IR Grid 5 Click board.

err_t irgrid5_default_cfg ( irgrid5_t *ctx );

• irgrid5_get_device_id This function reads the device ID from the IR Grid 5 EEPROM.

err_t irgrid5_get_device_id ( irgrid5_t *ctx, uint16_t *device_id );

• irgrid5_get_fw_version This function reads the firmware version from the IR Grid 5 flash memory.

err_t irgrid5_get_fw_version ( irgrid5_t *ctx, uint8_t *fw_ver );

• irgrid5_get_measurement This function reads object temperature image and sensor internal temperatures from the IR Grid 5 device.

err_t irgrid5_get_measurement ( irgrid5_t *ctx, float *obj_image, float *sensor_temp );

Application Init

Initializes the log interface and the IR Grid 5 Click driver. Reads and displays the device ID and firmware version.

void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    irgrid5_cfg_t irgrid5_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.
    irgrid5_cfg_setup( &irgrid5_cfg );
    IRGRID5_MAP_MIKROBUS( irgrid5_cfg, MIKROBUS_POSITION_IRGRID5 );
    if ( I2C_MASTER_ERROR == irgrid5_init( &irgrid5, &irgrid5_cfg ) ) 
    {
        log_error( &logger, " Communication init." );

    }

    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }

    uint16_t device_id[ 4 ] = { 0 };
    if ( IRGRID5_OK == irgrid5_get_device_id ( &irgrid5, device_id ) )
    {
        log_printf ( &logger, " Device ID: %.4X%.4X%.4X%.4X\r\n", 
                     device_id[ 0 ], device_id[ 1 ], device_id[ 2 ], device_id[ 3 ] );
    }

    uint8_t fw_ver[ 3 ] = { 0 };
    if ( IRGRID5_OK == irgrid5_get_fw_version ( &irgrid5, fw_ver ) )
    {
        log_printf ( &logger, " FW version: %u.%u.%u\r\n", 
                     ( uint16_t ) fw_ver[ 0 ], ( uint16_t ) fw_ver[ 1 ], ( uint16_t ) fw_ver[ 2 ] );
    }
    
    log_info( &logger, " Application Task " );
}

Application Task

Reads the sensor internal temperature and the object temperature image from the pixel array and displays them on the USB UART terminal every 500ms.

void application_task ( void )
{
    float sensor_temp = 0;
    float obj_image[ IRGRID5_NUM_PIXELS ] = { 0 };
    if ( IRGRID5_OK == irgrid5_get_measurement ( &irgrid5, obj_image, &sensor_temp ) )
    {
        log_printf( &logger, " Sensor temperature: %.1f degC\r\n", sensor_temp );
        log_printf( &logger, "--- Object temperature image ---\r\n" );
        for ( uint16_t pixel_cnt = 0; pixel_cnt < IRGRID5_NUM_PIXELS; pixel_cnt++ ) 
        {
            log_printf( &logger, "%.1f ", obj_image[ pixel_cnt ] );
            if ( 31 == ( pixel_cnt % 32 ) ) 
            {
                log_printf( &logger, "\r\n" );
            }
        }
        log_printf( &logger, "--------------------------------\r\n" );
    }
}

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.
