Click library

Software Support

We provide a library for the Barometer2 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 Barometer2 Click driver.

Standard key functions :

Example key functions :

Examples Description

The example starts off with the initialization and configuration of the click and logger modules, tests the communication channel and reads and displays temperature and pressure values every second.

The demo application is composed of two sections :

Application Init

Initializes and configures the click and logger modules and tests the communication for errors.

{
log_cfg_t log_cfg;
uint8_t test;
// 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.
BAROMETER2_MAP_MIKROBUS( cfg, MIKROBUS_1 );
barometer2_init( &barometer2, &cfg );
barometer2_default_cfg( &barometer2 );
// Test communication
if ( test == BAROMETER2_WHO_AM_I )
{
log_printf( &logger, "---- Communication OK!!! ----\r\n" );
}
else
{
log_printf( &logger, "---- Communication ERROR!!! ----\r\n" );
for ( ; ; );
}
// Software reset
barometer2_software_reset( &barometer2 );
Delay_1sec();
Delay_1sec( );
log_printf( &logger, "---- Start Measurement ---- \r\n" );
}

Application Task

Reads and displays temperature and pressure values every second.

{
float temperature;
float pressure;
log_printf( &logger, " Temperature : %f ", temperature );
log_printf( &logger, " Pressure : %f \n", pressure );
log_printf( &logger, "--------------------------\n" );
Delay_ms( 1000 );
}

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.
