Click library

Software Support

We provide a library for the AirQuality3 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 AirQuality3 Click driver.

Standard key functions :

Example key functions :

Examples Description

The demo application shows air quality measurement.

The demo application is composed of two sections :

Application Init

Configuring clicks and log objects. Settings the click in the default configuration. Call the procedure the wakeup function of the chip.

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.
AIRQUALITY3_MAP_MIKROBUS( cfg, MIKROBUS_1 );
airquality3_init( &airquality3, &cfg );
// Wake-up click procedure
airquality3_hardware_reset( &airquality3 );
airquality3_default_cfg( &airquality3 );
Delay_ms( 500 );
log_info( &logger, "---- Start measurement ----" );
}

Application Task

Reads CO2 and TVOC value in the air and logs this data on the USBUART.

void application_task ( void )
{
// Task implementation.
airquality3_get_co2_and_tvoc ( &airquality3, &air_data );
log_printf( &logger, "\r\n---- AirQuality data ----\r\n" );
log_printf( &logger, ">> CO2 data is %d ppm.\r\n", air_data.co2 );
log_printf( &logger, ">> TVOC data is %d ppb.\r\n", air_data.tvoc );
Delay_1sec();
}

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.
