Click library

  • Author : MikroE Team
  • Date : Dec 2019.
  • Type : I2C type

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 :

  • Config Object Initialization function.

    void ndirco2_cfg_setup ( ndirco2_cfg_t *cfg );

  • Initialization function.

    NDIRCO2_RETVAL ndirco2_init ( ndirco2_t ctx, ndirco2_cfg_t cfg );

Example key functions :

  • CO2 Concentration Read function

    void ndirco2_read_co2 ( ndirco2_t ctx, uint8_t set_check_mode, uint16_t output_data );

  • Average Complete Check function

    uint8_t ndirco2_check_average_complete ( ndirco2_t *ctx );

  • Mode Set function

    void ndirco2_set_mode ( ndirco2_t *ctx, uint8_t select_mode );

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;
    ndirco2_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 ----" );

    //  Click initialization.

    ndirco2_cfg_setup( &cfg );
    NDIRCO2_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    ndirco2_init( &ndirco2, &cfg );

    Delay_ms ( 300 );

    ndirco2_reset( &ndirco2 );
    ndirco2_write_register( &ndirco2, NDIRCO2_AVERAGING_COUNT_REG, 0x03 );
    ndirco2_set_mode( &ndirco2, NDIRCO2_CONTINUOUS_OP_MODE );
    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.


void application_task ( )
{
    uint16_t co2_data;

    ndirco2_read_co2( &ndirco2, NDIRCO2_CHECK_EACH_MEASURE, &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.

Other mikroE Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.NDIRCO2

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.
