Library Description
The library contains all the necessary functions for successful work with IR Grid 3 Click board.
Key functions:
void irgrid3_deviceConfiguration() - Functions for device configurationExamples description
The application is composed of the three sections :
void applicationTask()
{
irgrid3_getPixelTemperature(&Ta,&pixelTemp[0]);
mikrobus_logWrite("Ambient temperature: ",_LOG_TEXT);
FloatToStr(Ta,demoText);
mikrobus_logWrite(demoText,_LOG_LINE);
mikrobus_logWrite(" ", _LOG_LINE);
mikrobus_logWrite("--- Pixel temperature matrix 32x24 ---", _LOG_LINE);
for ( cnt = 0 ; cnt < 768 ; cnt++)
{
FloatToStr(pixelTemp[cnt],demoText);
demoText[ 5 ] = 0 ;
mikrobus_logWrite(demoText, _LOG_TEXT);
mikrobus_logWrite("|", _LOG_TEXT);
Delay_1ms();
if(((cnt % 32) == 0) && (cnt > 0))
{
mikrobus_logWrite(" ", _LOG_LINE);
}
}
mikrobus_logWrite(" ", _LOG_LINE);
Delay_ms( 500 );
}
Note: The sensor needs about 4 minutes for calibration.

I2CAdditional notes and information
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.
