Pressure 11 Click

Pressure 11 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 : May 2020.
• Type : I2C/SPI type

Software Support

Example Description

This sensor offers many benefits, including low power consumption, high resolution of the pressure data, embedded thermal compensation, FIFO buffer with several operating modes, temperature measurement, etc.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Pressure11

Example Key Functions

• pressure11_cfg_setup Config Object Initialization function.

void pressure11_cfg_setup ( pressure11_cfg_t *cfg );

• pressure11_init Initialization function.

err_t pressure11_init ( pressure11_t *ctx, pressure11_cfg_t *cfg );

• pressure11_check_id Functions for cheking commuincation with the chip and checking its ID.

uint8_t pressure11_check_id ( pressure11_t *ctx );

• pressure11_get_temperature Functions for temperature reading.

float pressure11_get_temperature ( pressure11_t *ctx );

• pressure11_get_pressure Functions for pressure reading.

float pressure11_get_pressure ( pressure11_t *ctx );

Application Init

Initializes SPI driver and checks chip ID

void application_init ( void )
{
    log_cfg_t log_cfg;
    pressure11_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 ----" );

    pressure11_cfg_setup( &cfg );
    PRESSURE11_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    pressure11_init( &pressure11, &cfg );
}

Application Task

Reads Pressure and Temperature values and displays it on UART LOG

void application_task ( void )
{
    float temperature;
    float pressure;
        
    temperature = pressure11_get_temperature( &pressure11 );
    log_printf( &logger, "Temperature: %.2f \r\n", temperature );
    log_printf( &logger, " C" );
 
    pressure = pressure11_get_pressure( &pressure11 );
    log_printf( &logger, "Pressure:  %.2f \r\n", pressure );
    log_printf( &logger, "   hPa (mBar)" );
 
    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.
