Click library

  • Author : MikroE Team
  • Date : May 2024.
  • Type : I2C/SPI type

Software Support

We provide a library for the Pressure 23 07BA 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 Pressure 23 07BA Click driver.

Standard key functions :

  • pressure2307ba_cfg_setup Config Object Initialization function.

    void pressure2307ba_cfg_setup ( pressure2307ba_cfg_t *cfg );
  • pressure2307ba_init Initialization function.

    err_t pressure2307ba_init ( pressure2307ba_t *ctx, pressure2307ba_cfg_t *cfg );
  • pressure2307ba_default_cfg Click Default Configuration function.

    err_t pressure2307ba_default_cfg ( pressure2307ba_t *ctx );

Example key functions :

  • pressure2307ba_get_measurement_data Pressure 23 07BA gets the measurement data function.

    err_t pressure2307ba_get_measurement_data ( pressure2307ba_t *ctx, float *pressure, float *temperature );
  • pressure2307ba_get_calibration_data Pressure 23 07BA gets the calibration data function.

    err_t pressure2307ba_get_calibration_data ( pressure2307ba_t *ctx );
  • pressure2307ba_read_adc Pressure 23 07BA ADC data reading function.

    err_t pressure2307ba_read_adc ( pressure2307ba_t *ctx, uint8_t sel_data, uint32_t *adc_data );

Example Description

This example demonstrates the use of Pressure 23 07BA 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;  /**< Logger config object. */
    pressure2307ba_cfg_t pressure2307ba_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.
    pressure2307ba_cfg_setup( &pressure2307ba_cfg );
    PRESSURE2307BA_MAP_MIKROBUS( pressure2307ba_cfg, MIKROBUS_1 );
    err_t init_flag = pressure2307ba_init( &pressure2307ba, &pressure2307ba_cfg );
    if ( ( I2C_MASTER_ERROR == init_flag ) || ( SPI_MASTER_ERROR == init_flag ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    if ( PRESSURE2307BA_ERROR == pressure2307ba_default_cfg ( &pressure2307ba ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }

    log_info( &logger, " Application Task " );
    log_printf( &logger, " _______________________ \r\n" );
    Delay_ms ( 100 );
}

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 )
{
    static float temperature, pressure;
    if ( PRESSURE2307BA_OK == pressure2307ba_get_measurement_data( &pressure2307ba, &pressure, &temperature ) )
    {
        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.Pressure2307BA

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.

Light mix-sens Click is carrying TMD37253, an advanced proximity measurement, color sense (RGBC+IR), and digital ambient light sensing (ALS) device. The TMD37253 slim module package has been designed to accommodate a “single hole” aperture approach that incorporates an IR LED and factory calibrated LED driver. The proximity detection feature provides object detection (e.g., mobile device screen to the user’s ear) by photodiode detection of reflected IR energy (sourced by the integrated LED). The ALS detection feature provides photopic light intensity data. The color photodiodes have UV and IR blocking filters and a dedicated data converters producing 16-bit data.
