Click library

• Author : MikroE Team
• Date : May 2020.
• Type : I2C type

Software Support

We provide a library for the Grideye Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

This library contains API for Grideye Click driver.

Standard key functions :

• Config Object Initialization function.

  void grideye_cfg_setup ( grideye_cfg_t *cfg );

• Initialization function.

  GRIDEYE_RETVAL grideye_init ( grideye_t ctx, grideye_cfg_t cfg );

• Click Default Configuration function.

  void grideye_default_cfg ( grideye_t *ctx );

Example key functions :

• Generic write function.

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

• Generic read function.

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

• Write data function

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

Examples Description

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

The demo application is composed of two sections :

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 );
}  

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Other mikroE Libraries used in the example:

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

Additional notes and informations

Depending on the development board you are using, you may need USB UART click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.
