Barometer 13 click

Barometer 13 Click is a compact add-on board that measures air pressure in a specific environment. This board features the BMP585, a barometric pressure sensor from Bosch Sensortec. It has a nominal operating pressure range of 30 up to 125kPa and a temperature operating range from -40 to +85°C. The sensor provides true absolute pressure and temperature readings due to on-chip linearization and temperature compensation.

  • Author : Nenad Filipovic
  • Date : Sep 2023.
  • Type : I2C/SPI type

Software Support

We provide a library for the Barometer 13 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 13 Click driver.

Example Description

This example demonstrates the use of Barometer 13 Click board™ by reading and displaying the pressure and temperature measurements.

The demo application is composed of two sections :

Application Init

The initialization of I2C or SPI module and log UART. After driver initialization, the app sets the default configuration.

void application_init ( void )
{
log_cfg_t log_cfg;
barometer13_cfg_t barometer13_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
barometer13_cfg_setup( &barometer13_cfg );
BAROMETER13_MAP_MIKROBUS( barometer13_cfg, MIKROBUS_1 );
err_t init_flag = barometer13_init( &barometer13, &barometer13_cfg );
if ( ( I2C_MASTER_ERROR == init_flag ) || ( SPI_MASTER_ERROR == init_flag ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
if ( BAROMETER13_ERROR == barometer13_default_cfg ( &barometer13 ) )
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
log_printf( &logger, " ______________________ \r\n" );
}

Application Task

The demo application reads and 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 )
{
float pressure = 0, temperature = 0;
if ( ( BAROMETER13_OK == barometer13_get_measurement( &barometer13, &pressure, &temperature ) ) &&
barometer13_get_interrupt( &barometer13 ) )
{
log_printf( &logger, " Pressure : %.2f mBar \r\n", pressure );
log_printf( &logger, " Temperature : %.2f degC \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.Barometer13

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.
