Barometer 4 Click is a compact add-on board used to measure air pressure in a specific environment. This board features the ICP-10111, a high accuracy low power barometric and temperature sensor from TDK InvenSense. The ICP-10111 is based on MEMS capacitive technology providing ultra-low noise at the lowest power, enabling industry-leading relative accuracy, sensor throughput, and temperature stability. It comes with a configurable host interface that supports I2C serial communication and measures pressure in a range from 30kPa up to 110kPa with an accuracy of ±1Pa over a wide operating temperature range. This Click board™ is suited for various pressure-based applications, especially when low power consumption is required, home appliances such as airflow control in HVAC, water level detection, vertical velocity monitoring, weather forecasting, and many more.

Click library

  • Author : Nenad Filipovic
  • Date : Sep 2021.
  • Type : I2C type

Software Support

We provide a library for the Barometer4 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 Barometer4 Click driver.

Standard key functions :

  • barometer4_cfg_setup Config Object Initialization function.

    void barometer4_cfg_setup ( barometer4_cfg_t *cfg );
  • barometer4_init Initialization function.

    err_t barometer4_init ( barometer4_t *ctx, barometer4_cfg_t *cfg );
  • barometer4_default_cfg Click Default Configuration function.

    err_t barometer4_default_cfg ( barometer4_t *ctx );

Example key functions :

  • barometer4_get_pressure_and_temperature Barometer 4 get pressure and temperature function.

    err_t barometer4_get_pressure_and_temperature ( barometer4_t *ctx,  float *pressure, float *temperature );
  • barometer4_get_raw_data Barometer 4 get RAW data function.

    err_t barometer4_get_raw_data ( barometer4_t *ctx, uint16_t measurement_comd, uint32_t *pressure, uint16_t *temperature );
  • barometer4_soft_reset Barometer 4 software reset function.

    err_t barometer4_soft_reset ( barometer4_t *ctx );

Example Description

This library contains API for the Barometer 4 Click driver. The library initializes and defines the I2C bus drivers to write and read data from registers. This demo application shows an example of atmospheric pressure and temperature measurement.

The demo application is composed of two sections :

Application Init

The initialization of the I2C module and log UART. After driver initialization and default settings, the app display device ID.


void application_init ( void ) 
{
    log_cfg_t log_cfg;                /**< Logger config object. */
    barometer4_cfg_t barometer4_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.
    barometer4_cfg_setup( &barometer4_cfg );
    BAROMETER4_MAP_MIKROBUS( barometer4_cfg, MIKROBUS_1 );
    err_t init_flag = barometer4_init( &barometer4, &barometer4_cfg );
    if ( I2C_MASTER_ERROR == init_flag ) 
    {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );

        for ( ; ; );
    }

    barometer4_default_cfg ( &barometer4 );
    log_info( &logger, " Application Task " );
    log_printf( &logger, "----------------------------\r\n" );
    Delay_ms ( 100 );

    static uint16_t device_id;
    err_t err_flag = barometer4_get_device_id( &barometer4, &device_id );
    if ( BAROMETER4_ERROR == err_flag ) 
    {
        log_error( &logger, " Communication Error. " );
        log_info( &logger, " Please, run program again... " );

        for ( ; ; );
    }
    log_printf( &logger, " Device ID   : 0x%.4X \r\n", device_id );
    log_printf( &logger, "----------------------------\r\n" );
    Delay_ms ( 1000 );
}

Application Task

This is an example that shows the use of a Barometer 4 Click board™. Logs the atmospheric pressure [ Pa ] 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 pressure;
    static float temperature;

    barometer4_get_pressure_and_temperature( &barometer4, &pressure, &temperature );
    log_printf( &logger, " Pressure    : %.2f Pa\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.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Barometer4

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.

4x4 RGB 2 Click is a compact add-on board that contains a matrix of 16 intelligent RGB LEDs, forming a 4x4 display screen. This board features 16 IN-PC55TBTRGB, 5x5mm RGB LEDs with an integrated IC from Inolux. The LEDs feature an 8-bit color control in 256 steps (256-level greyscale) and a 5-bit brightness control in 32 steps. The intelligent LEDs are cascaded (daisy-chained); thus, every one of them can communicate with the host MCU using the same data lines.
