FAN 4 Click

FAN 4 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

Demo application shows basic use of Fan 4 Click.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Fan4

Example Key Functions

• fan4_cfg_setup Config Object Initialization function.

void fan4_cfg_setup ( fan4_cfg_t *cfg );

• fan4_init Initialization function.

err_t fan4_init ( fan4_t *ctx, fan4_cfg_t *cfg );

• fan4_default_cfg Click Default Configuration function.

void fan4_default_cfg ( fan4_t *ctx );

• fan4_check_diagnostic Check diagnostic.

uint8_t fan4_check_diagnostic ( fan4_t *ctx );

• Set output voltage err_t fan4_set_output ( fan4_t *ctx, uint16_t output_volt, uint8_t boost_start_timer );

Application Init

Configuring Clicks and log objects. Settings the Click in the default configuration.

void application_init ( void )
{
    log_cfg_t log_cfg;
    fan4_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.

    fan4_cfg_setup( &cfg );
    FAN4_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    fan4_init( &fan4, &cfg );

    fan4_default_cfg( &fan4 );
}

Application Task

Increases the output voltage every 500 ms until it reaches the maximum fan voltage. Prints current voltase data on usbuart.

void application_task ( void )
{
    uint16_t voltage;

    //  Task implementation.

    voltage = FAN4_MIN_VOLT_SCALE;

    while ( voltage <= FAN4_MAX_VOLT_SCALE )
    {
        voltage += ( FAN4_DAC_LSB * 4 );
        log_info( &logger, "** Voltage is %d mV", voltage );

        fan4_set_output( &fan4, voltage, FAN4_BOOST_START_TIMER_DIS );
        Delay_ms ( 500 );
    }
}

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.
