Pressure 8 Click

Pressure 8 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 application reads pressure data.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Pressure8

Example Key Functions

• pressure8_cfg_setup Config Object Initialization function.

void pressure8_cfg_setup ( pressure8_cfg_t *cfg ); 

• pressure8_init Initialization function.

err_t pressure8_init ( pressure8_t *ctx, pressure8_cfg_t *cfg );

• pressure8_get_pressure Functions for get Pressure data

float pressure8_get_pressure ( pressure8_t *ctx, uint8_t press_format );

• pressure8_get_device_status Functions for get device status

uint8_t pressure8_get_device_status ( pressure8_t *ctx );

• pressure8_set_psi_range Functions for set PSI range

void pressure8_set_psi_range ( pressure8_t *ctx, float psi_min, float psi_max );

Application Init

Initialization device and logger module, reset device and set PSI range.

void application_init ( void )
{
    log_cfg_t log_cfg;
    pressure8_cfg_t cfg;

    /** 
     * 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.
    pressure8_cfg_setup( &cfg );
    PRESSURE8_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    pressure8_init( &pressure8, &cfg );

    pressure8_device_reset( &pressure8 );
    pressure8_set_psi_range( &pressure8, 0, 25 );
    Delay_ms ( 1000 );
    
    log_info( &logger, " Application Task " );
}

Application Task

Reads pressure data in mBar and logs it on the USB UART once per second.

void application_task ( void )
{
    float pressure = 0;
    
    pressure = pressure8_get_pressure( &pressure8, PRESSURE8_DATA_IN_MBAR );
    log_printf( &logger, " Pressure: %.1f mBar\r\n", pressure );

    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.
