Click library

  • Author : Stefan Ilic
  • Date : May 2023.
  • Type : I2C type

Software Support

We provide a library for the Barometer 12 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 from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for Barometer 12 Click driver.

Example Description

This library contains API for the Barometer 12 Click driver.

The library initializes and defines the I2C bus drivers to write and read data from registers. This demo application shows an example of atmospheric pressure and temperature measurement.

The demo application is composed of two sections :

Application Init

The initialization of the I2C module and log UART.

After driver initialization and default settings, the app display device ID.

void application_init ( void )
{
log_cfg_t log_cfg;
barometer12_cfg_t barometer12_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
barometer12_cfg_setup( &barometer12_cfg );
BAROMETER12_MAP_MIKROBUS( barometer12_cfg, MIKROBUS_1 );
if ( I2C_MASTER_ERROR == barometer12_init( &barometer12, &barometer12_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
if ( BAROMETER12_ERROR == barometer12_default_cfg ( &barometer12 ) )
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
static uint16_t device_id;
err_t err_flag = barometer12_get_device_id( &barometer12, &device_id );
if ( BAROMETER12_ERROR == err_flag )
{
log_error( &logger, " Communication Error. " );
log_info( &logger, " Please, run program again... " );
for ( ; ; );
}
log_printf( &logger, " Device ID : 0x%.4X \r\n", device_id );
log_printf( &logger, "----------------------------\r\n" );
Delay_ms( 1000 );
log_info( &logger, " Application Task " );
}

Application Task

This is an example that shows the use of a Barometer 12 Click boardâ„¢.

Logs the atmospheric pressure [ Pa ] and temperature [ degree Celsius ] data. Results are being sent to the Usart Terminal where you can track their changes.

void application_task ( void )
{
float pressure;
float temperature;
barometer12_get_pressure_and_temperature( &barometer12, &pressure, &temperature );
log_printf( &logger, " Pressure : %.2f Pa\r\n", pressure );
log_printf( &logger, " Temperature : %.2f C\r\n", temperature );
log_printf( &logger, "----------------------------\r\n" );
Delay_ms( 1000 );
}
void application_task(void)
Definition: main.c:84

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Barometer12

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. UART terminal is available in all MikroElektronika compilers.
