Click library

  • Author : Nenad Filipovic
  • Date : Jul 2021.
  • Type : I2C/SPI type

Software Support

We provide a library for the Pressure16 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 from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for Pressure16 Click driver.

Standard key functions :

  • pressure16_cfg_setup Config Object Initialization function.

    void pressure16_cfg_setup ( pressure16_cfg_t *cfg );
  • pressure16_init Initialization function.

    PRESSURE16_RETVAL pressure16_init ( pressure16_t *ctx, pressure16_cfg_t *cfg );
  • pressure16_default_cfg Click Default Configuration function.

    void pressure16_default_cfg ( pressure16_t *ctx );

Example key functions :

  • pressure16_get_press_temp Pressure 16 get pressure and temperature function.

    PRESSURE16_RETVAL pressure16_get_press_temp ( pressure16_t *ctx, float *pressure, float *temperature );
  • pressure16_set_ctrl_config Pressure 16 set control configuration function.

    PRESSURE16_RETVAL pressure16_set_ctrl_config( pressure16_t *ctx, pressure16_ctrl_cfg_t ctrl_cfg_data );
  • pressure16_get_device_id Pressure 16 get device ID function.

    PRESSURE16_RETVAL pressure16_get_device_id ( pressure16_t *ctx, uint8_t *dev_id );

Example Description

This library contains API for the Pressure 16 Click driver. This demo application shows an example of pressure and temperature measurement.

The demo application is composed of two sections :

Application Init

Initialization of I2C and SPI module and log UART. After driver initialization and default settings, the app display retrieves the sensor parameters such as pressure and temperature.


void application_init ( void ) 
{
    log_cfg_t log_cfg;                /**< Logger config object. */
    pressure16_cfg_t pressure16_cfg;  /**< Click config object. */

    /** 
     * 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.
    pressure16_cfg_setup( &pressure16_cfg );
    PRESSURE16_MAP_MIKROBUS( pressure16_cfg, MIKROBUS_1 );
    err_t init_flag  = pressure16_init( &pressure16, &pressure16_cfg );
    if ( ( I2C_MASTER_ERROR == init_flag ) || ( SPI_MASTER_ERROR == init_flag ) ) 
    {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );

        for ( ; ; );
    }

    pressure16_default_cfg ( &pressure16 );
    log_info( &logger, " Application Task " );

    pressure16_get_device_id( &pressure16, &device_id );
    if ( device_id == PRESSURE16_DEVICE_ID ) {
        log_info( &logger, " Communication OK" );    
    } else {
        log_info( &logger, " Communication ERROR" ); 
        log_info( &logger, " Please, run program again... " );

        for ( ; ; );
    }

    log_printf( &logger, "---------------------------\r\n" );
    log_printf( &logger, "      Start measuring\r\n" );
    log_printf( &logger, "---------------------------\r\n" );
    Delay_ms ( 100 );
}

Application Task

This is an example that shows the use of a Pressure 16 Click board™. Logs the pressure [ mbar ] and temperature [ degree Celsius ] data. Results are being sent to the Usart Terminal where you can track their changes.


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

    pressure16_get_press_temp( &pressure16, &pressure, &temperature );
    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 );
}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Pressure16

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. UART terminal is available in all MikroElektronika compilers.

IR eclipse click

5

This is a example which demonstrates the use of IR eclipse click board. The EE-SS198 is a photointerrupter sensor that consists of an IR diode and phototransistor in one package When the beam from the transmitter is eclipsed by placing an object in the gap (like a piece of paper), the sensor is activated.

SPI Extend Click is a compact add-on board for applications that require extending the SPI communication bus over a long distance. This board features the LTC4332, an SPI slave extender device, from Analog Devices. Using a ±60V fault protected differential transceiver, the LTC4332 can transmit SPI data, including an interrupt signal, up to 2MHz over two twisted-pair cables.
