Click library

  • Author : Nenad Filipovic
  • Date : May 2023.
  • Type : ADC/I2C type

Software Support

We provide a library for the Diff Press 3 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 Diff Press 3 Click driver.

Standard key functions :

  • diffpress3_cfg_setup Config Object Initialization function.

    void diffpress3_cfg_setup ( diffpress3_cfg_t *cfg );
  • diffpress3_init Initialization function.

    err_t diffpress3_init ( diffpress3_t *ctx, diffpress3_cfg_t *cfg );

Example key functions :

  • diffpress3_get_pressure Diff Press 3 get pressure function.

    err_t diffpress3_get_pressure ( diffpress3_t *ctx, float *pressure );
  • diffpress3_get_temperature Diff Press 3 get temperature function.

    err_t diffpress3_get_temperature ( diffpress3_t *ctx, float *temperature );
  • diffpress3_read_raw_adc Diff Press 3 read raw ADC value function.

    err_t diffpress3_read_raw_adc ( diffpress3_t *ctx, uint16_t *raw_adc, diffpress3_d_sel_t data_sel );

Example Description

This library contains API for the Diff Press 3 Click driver. This demo application shows an example of differential pressure and temperature measurement.

The demo application is composed of two sections :

Application Init

Initialization of I2C and ADC module and log UART.

void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    diffpress3_cfg_t diffpress3_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.
    diffpress3_cfg_setup( &diffpress3_cfg );
    DIFFPRESS3_MAP_MIKROBUS( diffpress3_cfg, MIKROBUS_1 );
    err_t init_flag = diffpress3_init( &diffpress3, &diffpress3_cfg );
    if ( ( ADC_ERROR == init_flag ) || ( I2C_MASTER_ERROR == init_flag ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    log_info( &logger, " Application Task " );
    log_printf( &logger, "---------------------\r\n" );
    Delay_ms ( 100 );
}

Application Task

This example demonstrates the use of the Diff Press 3 Click board™. The demo application measures and display the Differential Pressure [kPa] and Temperature [degree Celsius] data. Results are being sent to the UART Terminal, where you can track their changes.

void application_task ( void ) 
{
    float pressure, temperature;
    if ( DIFFPRESS3_OK == diffpress3_get_pressure( &diffpress3, &pressure ) )
    {
        log_printf( &logger, " Diff Pressure: %.3f [kPa]\r\n", pressure );
        Delay_ms ( 100 );
    }
    if ( DIFFPRESS3_OK == diffpress3_get_temperature( &diffpress3, &temperature ) )
    {
        log_printf( &logger, " Temperature: %.2f [C]\r\n", temperature );
        Delay_ms ( 100 );
    }
    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.DiffPress3

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.

Battery Source Click is a compact add-on board designed to boost power from a battery for portable applications. This board features the TPS81256, a high-efficiency step-up converter from Texas Instruments. The board boosts input voltage (2.5V to 5.5V) to 5V/1A on a USB Type-C connector. It operates at a 4MHz switching frequency, enters Power-Save mode at light loads, and reduces supply current to 43μA during light load operation. The board supports over 3W output power and has an input current of less than 1µA in shutdown mode, maximizing battery life.
