Click library

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

Software Support

We provide a library for the Pressure4 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 Pressure4 Click driver.

Standard key functions :

  • pressure4_cfg_setup Config Object Initialization function.

    void pressure4_cfg_setup ( pressure4_cfg_t *cfg ); 
  • pressure4_init Initialization function.

    err_t pressure4_init ( pressure4_t *ctx, pressure4_cfg_t *cfg );
  • pressure4_default_cfg Click Default Configuration function.

    void pressure4_default_cfg ( pressure4_t *ctx );

Example key functions :

  • pressure4_read_id This function returns the contents of the chipid register.

    uint8_t pressure4_read_id ( pressure4_t *ctx );
  • pressure4_get_temperature This function returning the calculated temperature value.

    float pressure4_get_temperature ( pressure4_t *ctx );
  • pressure4_get_pressure This function returning the calculated value of the pressure.

    float pressure4_get_pressure ( pressure4_t *ctx );

Examples Description

This app measure barometric pressure.

The demo application is composed of two sections :

Application Init

Initializes the Click board.


void application_init ( void )
{
    log_cfg_t log_cfg;
    pressure4_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.
    pressure4_cfg_setup( &cfg );
    PRESSURE4_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    pressure4_init( &pressure4, &cfg );

    pressure4_default_cfg( &pressure4 );
    log_info( &logger, " Application Task " );
}

Application Task

The pressure and temperature data is read from the sensor and it is printed to the UART.


void application_task ( void )
{
    float pressure = 0;
    float temperature = 0;

    temperature = pressure4_get_temperature( &pressure4 );
    log_printf( &logger, "Temperature : %.2f degC\r\n", temperature );
    Delay_ms ( 100 );

    pressure = pressure4_get_pressure( &pressure4 );
    log_printf( &logger, "Pressure : %.2f mBar\r\n", pressure );
    log_printf( &logger, "========================\r\n" );

    Delay_ms ( 500 );
} 

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.Pressure4

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.
