Barometer 5 Click is a compact add-on board used to measure air pressure in a specific environment. This board features the MS5637-02BA03, a high accuracy low voltage barometric and temperature sensor from TE Connectivity Measurement Specialties. The MS5637-02BA03 includes a high-linearity pressure sensor and an ultra-low-power 24-bit ΔΣ ADC with internal factory-calibrated coefficients, providing a precise digital 24-bit pressure and temperature value, and different operation modes allowing the user to optimize for conversion speed and current consumption. It comes with a configurable host interface that supports I2C serial communication and measures pressure in a range from 300mbar up to 1.2bar with an accuracy of ±2mbar over a wide operating temperature range.

We provide a library for the Barometer5 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.
This library contains API for Barometer 5 Click driver.
barometer5_cfg_setup
Config Object Initialization function.
void barometer5_cfg_setup ( barometer5_cfg_t *cfg );
barometer5_init
Initialization function.
err_t barometer5_init ( barometer5_t *ctx, barometer5_cfg_t *cfg );
barometer5_default_cfg
Click Default Configuration function.
err_t barometer5_default_cfg ( barometer5_t *ctx );
barometer5_get_data
Barometer 5 get data function.
err_t barometer5_get_data ( barometer5_t *ctx, float *temperature, float *pressure );
barometer5_get_pressure
Barometer 5 get pressure data function.
err_t barometer5_get_pressure ( barometer5_t *ctx, float *pressure );
barometer5_get_temperature
Barometer 5 get temperature data function.
err_t barometer5_get_temperature ( barometer5_t *ctx, float *temperature );
This library contains API for Barometer 5 Click driver. The demo application reads and calculate temperature and pressure data.
The demo application is composed of two sections :
Initializes I2C driver and log UART. After driver initialization the app set default settings.
void application_init ( void )
{
log_cfg_t log_cfg; /**< Logger config object. */
barometer5_cfg_t barometer5_cfg; /**< Click config object. */
/**
* Logger initialization.
* Default baud rate: 115200
* Default log level: LOG_LEVEL_DEBUG
* @note If USB_UART_RX and USB_UART_TX
* are defined as HAL_PIN_NC, you will
* need to define them manually for log to work.
* See @b LOG_MAP_USB_UART macro definition for detailed explanation.
*/
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
barometer5_cfg_setup( &barometer5_cfg );
BAROMETER5_MAP_MIKROBUS( barometer5_cfg, MIKROBUS_1 );
if ( I2C_MASTER_ERROR == barometer5_init( &barometer5, &barometer5_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
if ( BAROMETER5_ERROR == barometer5_default_cfg ( &barometer5 ) )
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
log_printf( &logger, "---------------------------\r\n" );
Delay_ms ( 100 );
}
This is an example that demonstrates the use of the Barometer 5 Click board™. In this example, display the Pressure ( mBar ) and Temperature ( degree Celsius ) data. Results are being sent to the Usart Terminal where you can track their changes.
void application_task ( void )
{
static float temperature;
static float pressure;
if ( barometer5_get_data( &barometer5, &temperature, &pressure ) == BAROMETER5_OK )
{
log_printf( &logger, " Pressure : %.2f mbar \r\n", pressure );
log_printf( &logger, " Temperature : %.2f 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.

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.
