Grid-EYE 2 Click

Grid-EYE 2 Click is a compact add-on board designed for thermal imaging and motion detection applications. This board features the AMG883543, an infrared array sensor from Panasonic with a 90° viewing angle and an 8x8 pixel matrix that measures temperatures from 0°C to 80°C with a resolution of 0.25°C. The sensor can detect objects up to 5 meters away and outputs temperature data via a digital interface. The board also supports the Click Snap feature, allowing the main sensor area to be detached for flexible positioning.

Software Support

We provide a library for the Grid-EYE 2 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 from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for Grid-EYE 2 Click driver.

Example Description

This example demonstrates the use of Grid-EYE 2 Click by reading and displaying the temperature measurements as an 8x8 pixels grid.

The demo application is composed of two sections :

Application Init

Initializes the driver and performs the Click default configuration which enables the data ready interrupt and sets data measurement to 10 frames per second.

void application_init ( void )
{
log_cfg_t log_cfg;
grideye2_cfg_t grideye2_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
grideye2_cfg_setup( &grideye2_cfg );
GRIDEYE2_MAP_MIKROBUS( grideye2_cfg, MIKROBUS_1 );
if ( I2C_MASTER_ERROR == grideye2_init( &grideye2, &grideye2_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
if ( GRIDEYE2_ERROR == grideye2_default_cfg ( &grideye2 ) )
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
}

Application Task

Waits for a data ready interrupt and then reads the grid temperature measurements and displays the results on the USB UART in a form of an 8x8 pixels grid.

void application_task ( void )
{
// Wait for data ready interrupt
while ( grideye2_get_int_pin ( &grideye2 ) );
if ( GRIDEYE2_OK == grideye2_read_grid ( &grideye2 ) )
{
grideye2_clear_status ( &grideye2 );
for ( uint8_t cnt = 0; cnt < GRIDEYE2_NUM_PIXELS; cnt++ )
{
if ( 0 == ( cnt % 8 ) )
{
log_printf( &logger, "\r\n" );
}
log_printf( &logger, "%.2f ", grideye2.grid_temp[ cnt ] );
}
log_printf( &logger, "\r\n" );
}
}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.GridEYE2

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. UART terminal is available in all MikroElektronika compilers.
