Pressure 13 Click

Pressure 13 Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.

Example Description

This is an example which demonstrates the use of Pressure 13 Click board.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Pressure13

Example Key Functions

• pressure13_cfg_setup Config Object Initialization function.

void pressure13_cfg_setup ( pressure13_cfg_t *cfg );

• pressure13_init Initialization function.

err_t pressure13_init ( pressure13_t *ctx, pressure13_cfg_t *cfg );

• pressure13_read_an_pin_value Pressure 13 read AN pin value function.

err_t pressure13_read_an_pin_value ( pressure13_t *ctx, uint16_t *data_out );

• pressure13_read_an_pin_voltage Pressure 13 read AN pin voltage level function.

err_t pressure13_read_an_pin_voltage ( pressure13_t *ctx, float *data_out );

• pressure13_get_pressure Pressure 13 get pressure function.

err_t pressure13_get_pressure ( pressure13_t *ctx, float *data_out );

Application Init

Initialization driver enables - GPIO, initializes ADC, also write log.

void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    pressure13_cfg_t pressure13_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.
    pressure13_cfg_setup( &pressure13_cfg );
    PRESSURE13_MAP_MIKROBUS( pressure13_cfg, MIKROBUS_1 );
    if ( ADC_ERROR == pressure13_init( &pressure13, &pressure13_cfg ) )
    {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );

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

Application Task

Measure and display pressure ( mBar ). Results are being sent to the Usart Terminal where you can track their changes. All data logs on usb uart approximately every sec.

void application_task ( void ) 
{
    if ( pressure13_get_pressure( &pressure13, &pressure_val ) != ADC_ERROR ) {
        log_printf( &logger, " Pressure: %.3f [mBar]\r\n", pressure_val );
    }
    log_printf( &logger, "-------------------------\r\n" );
    Delay_ms ( 1000 );
}

Application Output

This Click board can be interfaced and monitored in two ways:

• Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
• UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
