Fan 3 click

Fan 3 click is the perfect choice for fan speed control and it can operate in seven discrete speed steps.

Click library

  • Author : MikroE Team
  • Date : Dec 2019.
  • Type : I2C type

Software Support

We provide a library for the Fan3 Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

This library contains API for Fan3 Click driver.

Standard key functions :

  • Config Object Initialization function.

void fan3_cfg_setup ( fan3_cfg_t *cfg );

  • Initialization function.

FAN3_RETVAL fan3_init ( fan3_t *ctx, fan3_cfg_t *cfg );

Example key functions :

  • Set speed

void fan3_set_speed ( fan3_t *ctx, uint8_t new_speed );

Examples Description

This application controls the fan speed.

The demo application is composed of two sections :

Application Init

Initializes the click device.

void application_init ( void )
{
    log_cfg_t log_cfg;
    fan3_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.

    fan3_cfg_setup( &cfg );
    FAN3_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    fan3_init( &fan3, &cfg );

    log_printf( &logger, ">>> Initialized...\r\n" );
}

Application Task

Cycles through different fan speeds, including 0 - stopped.

void application_task ( )
{
    log_printf( &logger, "Speed 1...\r\n" );
    fan3_set_speed( ctx, FAN3_SPEED1 );
    Delay_ms( 4000 );
    log_printf( &logger, "Speed 3...\r\n" );
    fan3_set_speed( ctx, FAN3_SPEED3 );
    Delay_ms( 4000 );
    log_printf( &logger, "Speed 5...\r\n" );
    fan3_set_speed( ctx, FAN3_SPEED5 );
    Delay_ms( 4000 );
    log_printf( &logger, "Speed 7...\r\n" );
    fan3_set_speed( ctx, FAN3_SPEED7 );
    Delay_ms( 4000 );
    log_printf( &logger, "Stopped...\r\n" );
    fan3_set_speed( ctx, FAN3_STOPPED );
    Delay_ms( 4000 );
}

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Other mikroE Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Fan3

Additional notes and informations

Depending on the development board you are using, you may need 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.
