Barometer 10 click

Barometer 10 Click is a compact add-on board that measures air pressure in a specific environment. This board features the LPS28DFW, an ultra-compact piezoresistive absolute pressure sensor that functions as a digital output barometer from STMicroelectronics. The LPS28DFW comprises a sensing element and an IC chip for signal processing in one package, converts pressure into a 24-bit digital value, and sends the information via I2C serial interface. It has a selectable dual full-scale absolute pressure range of up to 1260hPa and 4060hPa, with an absolute pressure accuracy of 0.5hPa over a wide operating temperature range.

Software Support

We provide a library for the Barometer 10 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 10 Click driver.

Example Description

This example demonstrates the use of the Barometer 10 Click boardâ„¢. The demo application reads and calculates pressure and temperature data.

The demo application is composed of two sections :

Application Init

The initialization of the I2C module, log UART and additional pins. After the driver init, the app executes a default configuration.

void application_init ( void )
{
log_cfg_t log_cfg;
barometer10_cfg_t barometer10_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
barometer10_cfg_setup( &barometer10_cfg );
BAROMETER10_MAP_MIKROBUS( barometer10_cfg, MIKROBUS_1 );
if ( I2C_MASTER_ERROR == barometer10_init( &barometer10, &barometer10_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
if ( BAROMETER10_ERROR == barometer10_default_cfg ( &barometer10 ) )
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
log_printf( &logger, "------------------------\r\n" );
}

Application Task

This example displays the Pressure [mBar] and Temperature [degree Celsius] data. Results are being sent to the UART Terminal, where you can track their changes.

void application_task ( void )
{
static float pressure, temperature;
if ( BAROMETER10_OK == barometer10_get_pressure( &barometer10, &pressure ) )
{
log_printf( &logger, " Pressure: %.2f [mbar] \r\n", pressure );
}
if ( BAROMETER10_OK == barometer10_get_temperature( &barometer10, &temperature ) )
{
log_printf( &logger, " Temperature : %.2f [deg c] \r\n", temperature );
}
log_printf( &logger, "------------------------\r\n" );
Delay_ms( 1000 );
}

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.Barometer10

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.
