Pressure 6 click

Pressure 6 Click features a simple, yet highly accurate and reliable pressure sensor labeled as BM1386GLV, produced by ROHM. This sensor is a piezo-resistive pressure sensor with internal thermal compensation, which greatly simplifies the pressure reading.

Click library

• Author : MikroE Team
• Date : Dec 2019.
• Type : I2C type

Software Support

We provide a library for the Pressure6 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 form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

‍The library initializes and defines the I2C bus driver and drivers that and offers a choice for writing data in register and read data from register. The library includes function for read Temperature and Pressure data.

Standard key functions :

• Config Object Initialization function.

  ‍void pressure6_cfg_setup ( pressure6_cfg_t *cfg );

  - Initialization function.

  ‍PRESSURE6_RETVAL pressure6_init ( pressure6_t *ctx, pressure6_cfg_t *cfg );

• Click Default Configuration function.

  ‍void pressure6_default_cfg ( pressure6_t *ctx );

Example key functions :

• This function gets the temperature data from the sensor.

  ‍uint8_t pressure6_get_temperature( pressure6_t *ctx );

  - This function turns the sensor on.

  ‍void pressure6_power_on( pressure6_t *ctx );

• This function gets pressure data from the sensor.

  ‍uint16_t pressure6_get_pressure( pressure6_t *ctx );

  Examples Description

‍The example gets the pressure and temperature values from the sensors and logs on terminal.

The demo application is composed of two sections :

Application Init

‍Driver initialization and powering ON procedure to wake up the sensor and seting up the measurement mode.

void application_init ( void )
{
    log_cfg_t log_cfg;
    pressure6_cfg_t cfg;
 
    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, "---- Application Init ----" );
 
    //  Click initialization.
 
    pressure6_cfg_setup( &cfg );
    PRESSURE6_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    pressure6_init( &pressure6, &cfg );
}

Application Task

‍Read Pressure data and Temperature data and logs data to USBUART every 1 sec.

void application_task ( void )
{
    //  Task implementation.
    
    pressure6_waiting_for_new_data( &pressure6 );
    Pressure = pressure6_get_pressure( &pressure6 );
    Temperature = pressure6_get_temperature( &pressure6 );
 
    log_printf( &logger, "Pressure: %u\r\n", pressure);
    log_printf( &logger, "Temperature: %u\r\n", temperature);
 
    Delay_ms ( 1000 );
} 

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Other mikroE Libraries used in the example:

• MikroSDK.Board
• MikroSDK.Log
• Click.Pressure6

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. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.
