Pressure 7 Click

Pressure 7 Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.

• Type : I2C type

Software Support

Example Description

This example reads temperature and pressure and logs it every 3 seconds.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Pressure7

Example Key Functions

• pressure7_cfg_setup Config Object Initialization function.

void pressure7_cfg_setup ( pressure7_cfg_t *cfg );

• pressure7_init Initialization function.

err_t pressure7_init ( pressure7_t *ctx, pressure7_cfg_t *cfg );

• pressure7_default_cfg Click Default Configuration function.

void pressure7_default_cfg ( pressure7_t *ctx );

• pressure7_read_PROM This function reads calibration data from PROM.

uint8_t pressure7_read_PROM ( pressure7_t *ctx );

• pressure7_start_measurement This function starts measurement and calculation data.

void pressure7_start_measurement ( pressure7_t *ctx );

• pressure7_get_sensor_data This function reads pressure and temperature data.

void pressure7_get_sensor_data ( pressure7_t *ctx, float *Temperature, float *Pressure );

Application Init

Initialize Logger and Click object and call pressure7_read_PROM() function.

void application_init ( void )
{
    log_cfg_t log_cfg;
    pressure7_cfg_t cfg;

    /** 
     * 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.

    pressure7_cfg_setup( &cfg );
    PRESSURE7_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    pressure7_init( &pressure7, &cfg );
    pressure7_default_cfg ( &pressure7 );

    //  Read calibrated data from the PROM

    prom_exit_value = pressure7_read_PROM( &pressure7 );
    if ( prom_exit_value == PRESSURE7_PROM_READ_OK )
    {
        log_info( &logger, "Read PROM - OK !\r\n" );
    }
    else
    {
        log_info( &logger, "Read PROM - ERROR!\r\n" );
    }
    Delay_ms ( 100 );
}

Application Task

Get sensor data on every 3 seconds and send measured temperature and pressure to logger.

void application_task ( void )
{
    pressure7_start_measurement( &pressure7 );
    pressure7_get_sensor_data( &pressure7, &Temperature, &Pressure );

    log_printf( &logger, "Temperature: %fC\r\n", Temperature );
    log_printf( &logger, "Pressure: %f\r\n", Pressure );

    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
}

Application Output

This Click board can be interfaced and monitored in two ways:

• Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
• UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
