Pressure 10 Click

Pressure 10 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.

Click Library

• Author : MikroE Team
• Date : Jun 2020.
• Type : I2C/SPI type

Software Support

Example Description

Pressure 10 Click features a digital interface barometric pressure sensor, based on piezoresistive bridge. It can use both SPI and I2C communication protocols, allowing it to be interfaced with a broad range of MCUs.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Pressure10

Example Key Functions

• pressure10_cfg_setup Config Object Initialization function.

void pressure10_cfg_setup ( pressure10_cfg_t *cfg );

• pressure10_init Initialization function.

err_t pressure10_init ( pressure10_t *ctx, pressure10_cfg_t *cfg );

• pressure10_default_cfg Click Default Configuration function.

void pressure10_default_cfg ( pressure10_t *ctx );

• pressure10_send_cmd Send command.

void pressure10_send_cmd ( pressure10_t *ctx, uint8_t cmd );

• pressure10_check_communication Check communication.

uint8_t pressure10_check_communication ( pressure10_t *ctx );

• pressure10_get_status Get status function.

void pressure10_get_status ( pressure10_t *ctx, pressure10_status_t *status_obj );

Application Init

Initializes the driver, checks the communication and configures the module for measurement.

void application_init ( void )
{
    log_cfg_t log_cfg;
    pressure10_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.

    pressure10_cfg_setup( &cfg );
    PRESSURE10_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    pressure10_init( &pressure10, &cfg );

    check_com = pressure10_check_communication( &pressure10 );
    if ( check_com == 0 )
    {
        log_printf( &logger, ">> Communication [OK]\r\n" );
    }
    else
    {
        log_printf( &logger, ">> Communication [ERROR]\r\n" );
        for( ; ; );
    }

    pressure10_default_cfg ( &pressure10 );
    log_printf( &logger, "----------------------------\r\n" );
}

Application Task

Reads the pressure and temperature data every 1500ms and displays the results on the USB UART.

void application_task ( void )
{
    float temperature;
    float pressure;

    pressure = pressure10_get_pressure( &pressure10 );
    temperature = pressure10_get_temperature( &pressure10 );

    log_printf( &logger, ">> Temperature: %.2f C\r\n", temperature );

    log_printf( &logger, "----------------------------\r\n" );

    log_printf( &logger, ">> Pressure: %.2f mBar\r\n", pressure );

    log_printf( &logger, "----------------------------\r\n" );

    Delay_ms ( 1000 );
    Delay_ms ( 500 );
}

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.
