Pressure 3 Click

Pressure 3 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.

Software Support

Example Description

This application is digital barometric pressure sensor.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Pressure3

Example Key Functions

• pressure3_cfg_setup Config Object Initialization function.

void pressure3_cfg_setup ( pressure3_cfg_t *cfg );

• pressure3_init Initialization function.

err_t pressure3_init ( pressure3_t *ctx, pressure3_cfg_t *cfg );

• pressure3_default_cfg Click Default Configuration function.

void pressure3_default_cfg ( pressure3_t *ctx );

• pressure3_get_t_p_data Get temperature pressure.

void pressure3_get_t_p_data ( pressure3_t *ctx, float *temperature, float *presure, pressure3_coeff_t *coeff_struct );

• pressure3_get_coefficients Get coefficients.

void pressure3_get_coefficients ( pressure3_t *ctx, pressure3_coeff_t *coeff_struct );

• pressure3_get_measurement_data Read the coefficients value for calculation function.

int32_t pressure3_get_measurement_data ( pressure3_t *ctx, uint8_t mbs_reg_addr );

Application Init

Initialization device, set default configuration and start to write log.

void application_init ( void )
{
    log_cfg_t log_cfg;
    pressure3_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 ----" );

    pressure3_cfg_setup( &cfg );
    PRESSURE3_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    pressure3_init( &pressure3, &cfg );
    pressure3_default_cfg( &pressure3 );
}

Application Task

This is an example which demonstrates the use of Pressure 3 Click board. Measured pressure and temperature data from the DPS310 sensor on Pressure 3 Click board. Results are being sent to the Usart Terminal where you can track their changes. All data logs write on usb uart changes for every 3 sec.

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

    pressure3_get_t_p_data( &pressure3, &temperature, &pressure, &coeff_struct );
    
    log_printf( &logger, " * Pressure: %.2f mbar * \r\n", pressure );
    log_printf( &logger, " * Temperature: %.2f C * \r\n", temperature );
    log_printf( &logger, " ----------------------- \r\n" );

    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.
