Click library

  • Author : Katarina Perendic
  • Date : nov 2019.
  • Type : I2C type

Software Support

We provide a library for the Fan4 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 Fan4 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void fan4_cfg_setup ( fan4_cfg_t *cfg );

  • Initialization function.

    FAN4_RETVAL fan4_init ( fan4_t ctx, fan4_cfg_t cfg );

  • Click Default Configuration function.

    void fan4_default_cfg ( fan4_t *ctx );

Example key functions :

  • Check diagnostic.

    uint8_t fan4_check_diagnostic ( fan4_t *ctx );

  • Set output voltage

    FAN4_RETVAL fan4_set_output ( fan4_t *ctx, uint16_t output_volt, uint8_t boost_start_timer );

Examples Description

Demo application shows basic use of Fan 4 Click.

The demo application is composed of two sections :

Application Init

Configuring clicks and log objects. Settings the Click in the default configuration.

void application_init ( void )
{
    log_cfg_t log_cfg;
    fan4_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.

    fan4_cfg_setup( &cfg );
    FAN4_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    fan4_init( &fan4, &cfg );

    fan4_default_cfg( &fan4 );
}

Application Task

Increases the output voltage every 500 ms until it reaches the maximum fan voltage. Prints current voltase data on usbuart.

void application_task ( void )
{
    uint16_t voltage;

    //  Task implementation.

    voltage = FAN4_MIN_VOLT_SCALE;

    while ( voltage <= FAN4_MAX_VOLT_SCALE )
    {
        voltage += ( FAN4_DAC_LSB * 4 );
        log_info( &logger, "** Voltage is %d mV", voltage );

        fan4_set_output( &fan4, voltage, FAN4_BOOST_START_TIMER_DIS );
        Delay_ms ( 500 );
    }
}

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.Fan4

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.
