Click library

  • Author : Luka Filipovic
  • Date : May 2021.
  • Type : I2C type

Software Support

We provide a library for the UltraLowPress 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 UltraLowPress Click driver.

Standard key functions :

  • ultralowpress_cfg_setup Config Object Initialization function.

    void ultralowpress_cfg_setup ( ultralowpress_cfg_t *cfg );
  • ultralowpress_init Initialization function.

    err_t ultralowpress_init ( ultralowpress_t *ctx, ultralowpress_cfg_t *cfg );

Example key functions :

  • ultralowpress_ready_to_read Ready to read.

    uint8_t ultralowpress_ready_to_read ( ultralowpress_t *ctx )
  • ultralowpress_get_press Read pressure.

    float ultralowpress_get_press ( ultralowpress_t *ctx )
  • ultralowpress_get_temp Read temperature.

    float ultralowpress_get_temp ( ultralowpress_t *ctx )

Example Description

This application reads the serial number of the sensor. If there were no errors it continues reading temperature and pressure data from the sensor.

The demo application is composed of two sections :

Application Init

Initializes host communication(UART and I2C). Reads devices serial number and logs it.


void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    ultralowpress_cfg_t ultralowpress_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.
    ultralowpress_cfg_setup( &ultralowpress_cfg );
    ULTRALOWPRESS_MAP_MIKROBUS( ultralowpress_cfg, MIKROBUS_1 );
    err_t init_flag = ultralowpress_init( &ultralowpress, &ultralowpress_cfg );
    if ( init_flag == I2C_MASTER_ERROR ) 
    {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );

        for ( ; ; );
    }
    //Serial number of sensor read
    uint16_t temp_read = 0;
    uint32_t serial_read = 0;
    init_flag = ultralowpress_generic_read( &ultralowpress, ULTRALOWPRESS_REG_SERIAL_NUM_H, &temp_read );
    serial_read = temp_read;
    serial_read <<= 16;
    init_flag |= ultralowpress_generic_read( &ultralowpress, ULTRALOWPRESS_REG_SERIAL_NUM_L, &temp_read );
    serial_read |= temp_read;

    if ( init_flag < 0 )
    {
        log_error( &logger, " Read" );
        for ( ; ; );
    }
    else
    {
        log_printf( &logger, " > Serial number: 0x%.8LX\r\n", serial_read );
    }

    Delay_ms ( 1000 );
    log_info( &logger, " Application Task " );
}

Application Task

Checks if data is available. When it's available it reads the temperature and pressure data from the sensor and logs it.


void application_task ( void ) 
{
    if ( ultralowpress_ready_to_read( &ultralowpress ) )
    {
        ultralowpress_clear_status( &ultralowpress );
        float temp = ultralowpress_get_temp( &ultralowpress );
        float press = ultralowpress_get_press( &ultralowpress );
        log_printf( &logger, " > Temperature[ C ]: %.2f\r\n > Pressure[ Pa ]: %.2f\r\n", temp, press );
    }
    Delay_ms ( 100 );
}

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.UltraLowPress

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.
