Pressure 5 Click

Pressure 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 : MikroE Team
• Date : Dec 2019.
• Type : I2C/SPI type

Software Support

Example Description

This example performs temperature & pressure measurement every 2 seconds.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Pressure5

Example Key Functions

• pressure5_cfg_setup Config Object Initialization function.

void pressure5_cfg_setup ( pressure5_cfg_t *cfg );

• pressure5_init Initialization function.

err_t pressure5_init ( pressure5_t *ctx, pressure5_cfg_t *cfg );

• pressure5_default_cfg Click Default Configuration function.

void pressure5_default_cfg ( pressure5_t *ctx );

• pressure5_update_coefficient This function allows you to update the calibration coefficient.

void pressure5_update_coefficient ( pressure5_t *ctx );

• pressure5_get_temperature_data This function gets temperature in Celsius.

float pressure5_get_temperature_data ( pressure5_t *ctx );

• pressure5_get_pressure_data This function gets pressure in mBar.

float pressure5_get_pressure_data ( pressure5_t *ctx );

Application Init

Initialize driver init, test comunication, software reset, update coefficient and configuration module for start measurement.

void application_init ( void )
{
    log_cfg_t log_cfg;
    pressure5_cfg_t cfg;
    uint8_t tmp;
err_t init_ret;

    /** 
     * 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.

    pressure5_cfg_setup( &cfg );
    PRESSURE5_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    pressure5_init( &pressure5, &cfg );
    pressure5_default_cfg( &pressure5 );
}

Application Task

Reads Pressure data in [mBar] and Temperature data in [C] and logs data every seconds.

void application_task ( void )
{
    //  Task implementation.

    temperature = pressure5_get_temperature_data( &pressure5 );
    log_printf( &logger, "Temperature: %.2f C\r\n", temperature );
    pressure = pressure5_get_pressure_data( &pressure5 );
    log_printf( &logger, "Pressure: %.2f mBar\r\n ", pressure );
    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.
