Click library

  • Author : Jovan Stajkovic
  • Date : Jan 2020.
  • Type : I2C/SPI type

Software Support

We provide a library for the Lps22hb 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 Lps22hb Click driver.

Standard key functions :

  • Config Object Initialization function.

    void lps22hb_cfg_setup ( lps22hb_cfg_t *cfg );

  • Initialization function.

    LPS22HB_RETVAL lps22hb_init ( lps22hb_t ctx, lps22hb_cfg_t cfg );

  • Click Default Configuration function.

    void lps22hb_default_cfg ( lps22hb_t *ctx );

Example key functions :

  • Click Default Configuration function.

    void lps22hb_default_cfg ( lps22hb_t *ctx );

  • Function gets pressure data, calculates and returns pressure.

    float lps22hb_get_pressure ( lps22hb_t *ctx );

  • Function gets temperature returns value in degrees Celsius.

    float lps22hb_get_temp ( lps22hb_t *ctx );

Examples Description

The demo application measures temperature and pressure.

The demo application is composed of two sections :

Application Init

Initalizes Click driver, resets the device, applies default settings and makes an initial log.


void application_init ( void )
{
    log_cfg_t log_cfg;
    lps22hb_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_printf( &logger, "--------------------------\r\n\n" );
    log_printf( &logger, "     Application  Init\r\n" );
    Delay_ms ( 100 );

    //  Click initialization.

    lps22hb_cfg_setup( &cfg );
    LPS22HB_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    lps22hb_init( &lps22hb, &cfg );

    log_printf( &logger, "--------------------------\r\n\n" );
    log_printf( &logger, " ------ LPS22HB Click ------\r\n" );
    log_printf( &logger, "--------------------------\r\n\n" );
    Delay_ms ( 1000 );

    lps22hb_default_cfg ( &lps22hb, &cfg );
    Delay_ms ( 100 );

    log_printf( &logger, " -- Initialization  done. --\r\n" );
    log_printf( &logger, "--------------------------\r\n\n" );
    Delay_ms ( 1000 );
}

Application Task

This is a example which demonstrates the use of LPS22HB Click board. By measuring temperature and pressure. The results are being sent to the USART terminal where you can track their changes.


void application_task ( void )
{
    pressure = lps22hb_get_pressure( &lps22hb );
    temperature = lps22hb_get_temp( &lps22hb );

    log_printf( &logger, "** Pressure is %.2f mBar\r\n", pressure );
    log_printf( &logger, "** Temperature is %.2f C \r\n", temperature );

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

    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    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.Lps22hb

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.

Button Y Click is a Click board™ equipped with the tactile switch, sometimes referred to as a pushbutton. A pushbutton is a component that is used very often in various designs, allowing the user to interact with the application. Although it sounds simple, a button needs to comply with a range of application requirements. It needs to have a very good mechanical endurance while retaining its specifications, a predictable bouncing time, a very low ON resistance, very high OFF resistance, and it needs to fulfill aesthetical requirements.
