Fan 8 Click Board

We provide a library for the Fan 8 Click Board™ as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

The package can be downloaded/installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe Github account.

Library Description

This library contains API for the Fan 8 Click Board™ driver.

Key Functions

• fan8_set_duty_cycle - This function sets the duty cycle of the selected fan channel and waits until the duty cycle is set at the PWM output.
• fan8_measure_rpm - This function measures the RPM of the selected fan channel.
• fan8_read_temperature - This function reads the temperature from the thermistor attached to the selected temperature channel.

Example Description

This example demonstrates the use of the Fan 8 Click Board™.

void application_task ( void )
{
    static uint8_t duty_cnt = FAN8_MIN_DUTY_CYCLE;
    static int8_t duty_inc = FAN8_DUTY_CYCLE_STEP_10;
    uint16_t fan_rpm = 0;
    float temperature = 0;
    
    if ( duty_cnt == FAN8_MAX_DUTY_CYCLE )
    {
        duty_inc = -FAN8_DUTY_CYCLE_STEP_10;
    }
    else if ( duty_cnt == ( FAN8_MIN_DUTY_CYCLE + FAN8_DUTY_CYCLE_STEP_10 ) )
    {
        duty_inc = FAN8_DUTY_CYCLE_STEP_10;
    }
    duty_cnt += duty_inc;
        
    log_printf( &logger, " - Channel 1 values -rn" );
    fan8_set_duty_cycle ( &fan8, FAN8_FAN_CHANNEL_1, duty_cnt );
    log_printf( &logger, " PWM Duty Cycle : %drn", ( uint16_t ) duty_cnt );
    fan8_measure_rpm ( &fan8, FAN8_FAN_CHANNEL_1, FAN8_2_PULSES_PER_REVOLUTION, &fan_rpm );
    log_printf( &logger, " Last measured fan RPM : %urn", fan_rpm );
    fan8_read_temperature ( &fan8, FAN8_TEMP_CHANNEL_1, &temperature );
    log_printf( &logger, " Temperature : %.2f Crnrn", temperature );
    
    log_printf( &logger, " - Channel 2 values -rn" );
    fan8_set_duty_cycle ( &fan8, FAN8_FAN_CHANNEL_2, duty_cnt );
    log_printf( &logger, " PWM Duty Cycle : %drn", ( uint16_t ) duty_cnt );
    fan8_measure_rpm ( &fan8, FAN8_FAN_CHANNEL_2, FAN8_2_PULSES_PER_REVOLUTION, &fan_rpm );
    log_printf( &logger, " Last measured fan RPM : %urn", fan_rpm );
    fan8_read_temperature ( &fan8, FAN8_TEMP_CHANNEL_2, &temperature );
    log_printf( &logger, " Temperature : %.2f Crnrn", temperature );
    
    if ( !fan8_check_fault_indicator ( &fan8 ) )
    {
        log_printf( &logger, " Fault detected!rnrn", temperature );
    }
    
    Delay_ms( 500 );
}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe Github account.

Other mikroE Libraries used in the example:

• MikroSDK.Board
• MikroSDK.Log
• Click.FAN8

Additional Notes and Information

Depending on the development board you are using, you may need a USB UART click, USB UART 2 click or RS232 click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.

mikroSDK

The Fan 8 Click Board™ is supported with mikroSDK - MikroElektronika Software Development Kit. To ensure proper operation of mikroSDK compliant Click board™ demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
