Click library

  • Author : MikroE Team
  • Date : jan 2020.
  • Type : I2C type

Software Support

We provide a library for the Fan 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 Fan Click driver.

Standard key functions :

  • Config Object Initialization function.

    void fan_cfg_setup ( fan_cfg_t *cfg );

  • Initialization function.

    FAN_RETVAL fan_init ( fan_t ctx, fan_cfg_t cfg );

Example key functions :

  • Generic write function.

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

  • Generic read function.

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

  • Fan Click lock registers.

    void fan_lock_registers ( fan_t *ctx, uint8_t lock );

Examples Description

This application is controller for powering and regulating.

The demo application is composed of two sections :

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 );
    }
}  

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.Fan

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.
