Click library

  • Author : MikroE Team
  • Date : Dec 2019.
  • Type : I2C/SPI type

Software Support

We provide a library for the Pressure3 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 form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

This library contains API for Pressure3 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void pressure3_cfg_setup ( pressure3_cfg_t *cfg );

  • Initialization function.

    PRESSURE3_RETVAL pressure3_init ( pressure3_t ctx, pressure3_cfg_t cfg );

  • Click Default Configuration function.

    void pressure3_default_cfg ( pressure3_t *ctx );

Example key functions :

  • Get temperature pressure.

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

  • Get coefficients.

    void pressure3_get_coefficients ( pressure3_t ctx, pressure3_coeff_t coeff_struct );

  • Read the coefficients value for calculation function.

    int32_t pressure3_get_measurement_data ( pressure3_t *ctx, uint8_t mbs_reg_addr );

Examples Description

This application is digital barometric pressure sensor.

The demo application is composed of two sections :

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 );
}  

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Other mikroE Libraries used in the example:

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

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. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.
