Altitude 5 Click

Altitude 5 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.

Click Library

  • Author : Nenad Filipovic
  • Date : Sep 2021.
  • Type : I2C type

Software Support

Example Description

This library contains API for Altitude 5 Click driver. The demo application reads ADC value, calculate pressure and altitude.

Example Libraries

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Altitude5

Example Key Functions

  • altitude5_cfg_setup Config Object Initialization function.
void altitude5_cfg_setup ( altitude5_cfg_t *cfg );
  • altitude5_init Initialization function.
err_t altitude5_init ( altitude5_t *ctx, altitude5_cfg_t *cfg );
  • altitude5_default_cfg Click Default Configuration function.
err_t altitude5_default_cfg ( altitude5_t *ctx );
  • altitude5_get_altitude Altitude 5 get altitude function.
err_t altitude5_get_altitude ( altitude5_t *ctx, float *altitude );
  • altitude5_get_pressure Altitude 5 get pressure function.
err_t altitude5_get_pressure ( altitude5_t *ctx, float *pressure );
  • altitude5_get_adc_voltage Altitude 5 get ADC voltage function.
err_t altitude5_get_adc_voltage ( altitude5_t *ctx, float *adc_vtg );

Application Init

Initializes I2C or analog driver and log UART. After driver initialization the app set default settings.

void application_init ( void ) 
{
    log_cfg_t log_cfg;              /**< Logger config object. */
    altitude5_cfg_t altitude5_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.
    altitude5_cfg_setup( &altitude5_cfg );
    ALTITUDE5_MAP_MIKROBUS( altitude5_cfg, MIKROBUS_1 );
    err_t init_flag = altitude5_init( &altitude5, &altitude5_cfg );
    if ( I2C_MASTER_ERROR == init_flag ) 
    {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );

        for ( ; ; );
    }

    altitude5_default_cfg ( &altitude5 );
    log_info( &logger, " Application Task " );
    log_printf( &logger, "----------------------------\r\n" );
    Delay_ms ( 100 );
}

Application Task

This is an example that demonstrates the use of the Altitude 5 Click board™. In this example, we read ADC values and display the Pressure ( mBar ) and Altitude ( m ) data. Results are being sent to the Usart Terminal where you can track their changes.

void application_task ( void ) 
{
    static float pressure;
    static float altitude;
    
    altitude5_get_pressure( &altitude5, &pressure );
    log_printf( &logger, " Pressure    : %.2f mBar \r\n", pressure );
    Delay_ms ( 100 );
    
    altitude5_get_altitude( &altitude5, &altitude );
    log_printf( &logger, " Altitude    : %.2f m \r\n", altitude );
    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.
