La carte Click Board™ Pressure 17 est une carte complémentaire compacte qui contient un capteur de pression à montage sur carte. Cette carte est équipée du BM1390GLV-Z, un capteur de pression piézorésistif de haute précision de Rohm Semiconductor. Le BM1390GLV-Z est livré avec une interface hôte configurable qui prend en charge la communication série I2C et mesure la pression dans une plage de 300 hPa à 1 300 hPa avec une précision de ± 1 hPa. Il dispose également d'une fonction de compensation de température intégrée qui effectue en interne une compensation de température pour les MEMS à l'intérieur de la puce, ce qui permet d'obtenir facilement des informations sur la pression, d'un FIFO intégré et d'un fonctionnement dans une plage de températures de -40 °C à 85 °C, ce qui garantit un fonctionnement stable dans des conditions extrêmes. Cette carte Click Board™ convient aux mesures de pression dans les applications automobiles, industrielles et grand public.
La carte Click Board™ Pressure 17 est prise en charge par une bibliothèque compatible mikroSDK, qui comprend des fonctions qui simplifient le développement logiciel. Cette carte Click Board™ est un produit entièrement testé, prêt à être utilisé sur un système équipé du socket mikroBUS™.
How Does The Pressure 17 Click Board™ Work?
The Pressure 17 Click Board™ as its foundation uses the BM1390GLV-Z, ultra-compact piezoresistive pressure sensor from Rohm Semiconductor. This MEMS-based absolute pressure sensor includes a sensing element, analog to digital converter, signal processing part, and digital interface that sends the digital pressure data to the host controller. The MEMS-based sensing element measures pressure in a range from 300hPa up to 1300hPa with an accuracy of ±1hPa over a wide operating temperature range at the industry's lowest power.
It also has a built-in temperature compensation function that internally performs temperature compensation for MEMS inside the chip, so it's easy to get pressure information, built-in FIFO, and operation in a temperature range of -40°C to 85°C, which ensures stable operation under extreme conditions.
The Pressure 17 Click Board™ communicates with MCU using the standard I2C 2-Wire interface to read data and configure settings, supporting Standard Mode operation with a clock frequency of 100kHz and Fast Mode up to 400kHz. It also possesses an additional interrupt signal, routed on the INT pin of the mikroBUS™ socket labelled as INT, indicating when a specific interrupt event occurs.
This Click board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. However, the Click board™ comes equipped with a library containing functions and an example code that can be used, as a reference, for further development.

Software Support
We provide a library for the Pressure 17 Click Board™ as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.
The package can be downloaded/installed directly from NECTO Studio The package Manager (recommended), downloaded from our LibStock™ or found on MikroE Github account.
Library Description
This library contains API for the Pressure 17 Click Board™ driver.
Key functions
-
pressure17_get_int_pinThis function returns the INT pin logic state. -
pressure17_read_dataThis function checks if the data is ready and then reads the pressure and temperature raw data and converts them to millibar and Celsius respectfully. -
pressure17_write_registerThis function writes a data byte to the selected register by using I2C serial interface.
Example Description
This example demonstrates the use of the Pressure 17 Click Board™ by reading and displaying the pressure and temperature data.
void application_task ( void )
{
if ( !pressure17_get_int_pin ( &pressure17 ) )
{
float pressure, temperature;
if ( PRESSURE17_OK == pressure17_read_data ( &pressure17, &pressure, &temperature ) )
{
log_printf ( &logger, " Pressure: %.2f mbarrn Temperature: %.2f Crnn", pressure, temperature );
}
}
}
The full application code, and ready to use projects can be installed directly from NECTO Studio The package Manager (recommended), downloaded from our LibStock™ or found on MikroE Github account.
Other MikroE Libraries used in the example:
- MikroSDK.Board
- MikroSDK.Log
- Click.Pressure17
Additional Notes and Information
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.
MIKROSDK
The Pressure 17 Click Board™ is supported with mikroSDK - MikroElektronika Software Development Kit. To ensure proper operation of mikroSDK compliant Click board™ demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
