Click library

Software Support

We provide a library for the Environment 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 Environment Click driver.

Standard key functions :

Example key functions :

Examples Description

Example demonstrates use of the Environment click board.

The demo application is composed of two sections :

Application Init

Initialize driver and sets default configuration for BME680 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.
ENVIRONMENT_MAP_MIKROBUS( cfg, MIKROBUS_1 );
environment_init( &environment , &cfg );
environment_default_cfg( &environment );
}

Application Task

This is an example which demonstrates the use of Environment Click board.

void application_task ( void )
{
// Task implementation.
temperature = environment_get_temperature( &environment);
log_printf( &logger, " Temperature : %f%c", temperature, deg_cel[0]);
humidity = environment_get_humidity( &environment );
log_printf( &logger, " Humidity : %f%%", humidity);
pressure = environment_get_pressure( &environment );
log_printf( &logger, " Pressure : %.3fmbar", pressure);
gas = environment_get_gas_resistance( &environment );
log_printf( &logger, " Gas Resistance : %ld\r\n", gas);
Delay_ms( 2000 );
}

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.
