Fan Click

Fan 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.

Software Support

Example Description

This application is controller for powering and regulating.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Fan

Example Key Functions

• fan_cfg_setup Config Object Initialization function.

void fan_cfg_setup ( fan_cfg_t *cfg );

• fan_init Initialization function.

err_t fan_init ( fan_t *ctx, fan_cfg_t *cfg );

• fan_generic_write Generic write function.

void fan_generic_write ( fan_t *ctx, uint8_t reg, uint8_t *data_buf, uint8_t len );

• fan_generic_read Generic read function.

void fan_generic_read ( fan_t *ctx, uint8_t reg, uint8_t *data_buf, uint8_t len );

• fan_lock_registers Fan Click lock registers.

void fan_lock_registers ( fan_t *ctx, uint8_t lock );

Application Init

Initialization driver init and init chip.

void application_init ( void )
{
    log_cfg_t log_cfg;
    fan_cfg_t fan_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.

    fan_cfg_setup( &fan_cfg );
    FAN_MAP_MIKROBUS( fan_cfg, MIKROBUS_1 );
    if ( fan_init( &fan, &fan_cfg ) == I2C_MASTER_ERROR )
    {
        log_info( &logger, "---- Application Init Error ----" );
        log_info( &logger, "---- Please, run program again ----" );

        for ( ; ; );
    }
    log_info( &logger, "---- Application Init Done ----" );
    fan_default_cfg( &fan );
    fan_pwm_base( &fan, FAN_PWM_BASE_FREQ_HALF_SCALE );
    log_info( &logger, "---- Application Program Running... ----\n" );
}

Application Task

Performs a control of the fan and reads rotation per minute (RPM). Results will be sent to the usb uart terminal.

void application_task ( void )
{
    for ( uint8_t duty = FAN_DUTY_RATIO_0_PER; duty <= FAN_DUTY_RATIO_100_PER;
          duty += FAN_DUTY_RATIO_10_PER )
    {
        fan_setting( &fan, duty );
        log_printf( &logger, " Duty Ratio : %u%%\r\n", (uint16_t)duty );
        Delay_ms ( 1000 );
        Delay_ms ( 1000 );

        uint16_t tacho = 0;

        fan_get_tach( &fan, &tacho );
        log_printf( &logger, " Rotation per minute : %urpm\r\n\n", tacho );
        Delay_ms ( 1000 );
        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.
