Fan 6 Click

Fan 6 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 demo application reads tachometer value which is calculated as rpm value, and reads temperature of external diode in celsius value.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Fan6

Example Key Functions

• fan6_cfg_setup Config Object Initialization function.

void fan6_cfg_setup ( fan6_cfg_t *cfg );

• fan6_init Initialization function.

err_t fan6_init ( fan6_t *ctx, fan6_cfg_t *cfg );

• fan6_default_cfg Click Default Configuration function.

void fan6_default_cfg ( fan6_t *ctx );

• fan6_read_eeprom This function reads 256 bytes from EEPROM.

void fan6_read_eeprom ( fan6_t *ctx, uint8_t *data_out );

• fan6_set_pwm_mode This function sets Fan on PWM mode and determines Fan speed (PWM duty).

void fan6_set_pwm_mode ( fan6_t *ctx, const uint8_t pwm_duty );

• fan6_read_tachometer This function reads current tachometer value and calculates that value in rpm.

uint32_t fan6_read_tachometer ( fan6_t *ctx );

Application Init

Initializes device configuration.

void application_init ( void )
{
    log_cfg_t log_cfg;
    fan6_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.

    fan6_cfg_setup( &cfg );
    FAN6_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    fan6_init( &fan6, &cfg );
    
    fan6_enable_device( &fan6, 1 );
    Delay_ms ( 500 );
    
    fan6_default_cfg( &fan6 );
    tachometer = 0;
}

Application Task

Reads tachometer value which is calculated as rpm value, and reads temperature of external diode in celsius value. All this results logs on USB UART. Repeats operation every 500 ms.>

void application_task ( void )
{
    float temp_diode;

    temp_diode = fan6_get_temperature( &fan6, FAN6_INTERNAL_TEMP_READ_REG );
    log_printf( &logger, "Temperature of DIODE is: %f - Cels \r\n", temp_diode );
    
    fan6_set_pwm_mode( &fan6, duty_cycle );
    
    duty_cycle += 5;
    
    tachometer = fan6_read_tachometer( &fan6 );
    log_printf( &logger, "Tachometer value is: %lu rpm \r\n", tachometer );
    log_printf( &logger, "---------------------------------------- \r\n", tachometer );
    
    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.
