Click library

  • Author : Katarina Perendic
  • Date : okt 2019.
  • Type : I2C/SPI type

Software Support

We provide a library for the Weather 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 Weather Click driver.

Standard key functions :

  • Config Object Initialization function.

    ‍void weather_cfg_setup ( weather_cfg_t *cfg );

    - Initialization function.

    ‍WEATHER_RETVAL weather_init ( weather_t *ctx, weather_cfg_t *cfg );

  • Click Default Configuration function.

    ‍void weather_default_cfg ( weather_t *ctx );

Example key functions :

‍This demo-app shows the temperature, pressure and humidity measurement using Weather click.

The demo application is composed of two sections :

Application Init

‍Configuring clicks and log objects. Setting the click in the default configuration to start the measurement.

void application_init ( void )
{
log_cfg_t log_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, "---- Application Init ----" );
// Click initialization.
WEATHER_MAP_MIKROBUS( cfg, MIKROBUS_1 );
weather_init( &weather, &cfg );
weather_default_cfg( &weather );
}
#define WEATHER_MAP_MIKROBUS(cfg, mikrobus)

void weather_default_cfg(weather_t *ctx)
Click Default Configuration function.
WEATHER_RETVAL weather_init(weather_t *ctx, weather_cfg_t *cfg)
Initialization function.
void weather_cfg_setup(weather_cfg_t *cfg)
Config Object Initialization function.

Application Task

‍Reads Temperature data, Relative Huminidy data and Pressure data, this data logs to USBUART every 1500ms.

void application_task ( void )
{
weather_data_t weather_data;
// Task implementation.
weather_get_ambient_data( &weather, &weather_data );
log_printf( &logger, " \r\n ---- Weather data ----- \r\n" );
log_printf( &logger, "[PRESSURE]: %.2f mBar.\n\r", weather_data.pressure );
log_printf( &logger, "[TEMPERATURE]: %.2f C.\n\r", weather_data.temperature );
log_printf( &logger, "[HUMIDITY]: %.2f %%.\n\r", weather_data.humidity );
Delay_ms( 1500 );
}
void weather_get_ambient_data(weather_t *ctx, weather_data_t *weather_data)
Weather 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.Weather

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.
