Click library

Software Support

We provide a library for the NDIRCO2 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 NDIRCO2 Click driver.

Standard key functions :

Example key functions :

Examples Description

This application measures absolute CO2 concetration.

The demo application is composed of two sections :

Application Init

Initializes I2C driver and performs driver reset and determines number of averaging measurements.

void application_init ( void )
{
log_cfg_t log_cfg;
// Logger initialization.
log_cfg.level = LOG_LEVEL_DEBUG;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, "---- Application Init ----" );
// Click initialization.
NDIRCO2_MAP_MIKROBUS( cfg, MIKROBUS_1 );
ndirco2_init( &ndirco2, &cfg );
Delay_ms( 300 );
ndirco2_reset( &ndirco2 );
log_printf( &logger, "NDIR CO2 is initialized \r\n" );
Delay_ms( 200 );
}

Application Task

Reads CO2 concentration data in ppm unit after each completed measurement. One measurement is finished after 300 ms, and period between two measurements is 2 seconds. Results of measurements logs on USBUART.

{
uint16_t co2_data;
log_printf( &logger, "CO2 concentration is: %d ppm \r\n", co2_data );
}

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.

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.
