Click library

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

Software Support

We provide a library for the Fan6 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 Fan6 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void fan6_cfg_setup ( fan6_cfg_t *cfg );

  • Initialization function.

    FAN6_RETVAL fan6_init ( fan6_t ctx, fan6_cfg_t cfg );

  • Click Default Configuration function.

    void fan6_default_cfg ( fan6_t *ctx );

Example key functions :

  • This function reads 256 bytes from EEPROM.

    void fan6_read_eeprom ( fan6_t ctx, uint8_t data_out );

  • 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 );

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

    uint32_t fan6_read_tachometer ( fan6_t *ctx );

Examples Description

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

The demo application is composed of two sections :

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 );
} 

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.Fan6

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.

Opto Encoder 4 Click

0

Opto Encoder 4 Click is a compact add-on board that contains an optical sensor/encoder that can be used for movement or rotation encoding. This board features the EE-SX4330, a transmissive photo-microsensor from OMRON. It is intended to be used with an encoder disk or similar device that will act as a barrier between the emitter and detector of the sensor. Usually, it will be the disk with perforations, which is commonly used to detect the rotation speed.

Pressure 22 Click is a compact add-on board that contains a board-mount pressure sensor. This board features the MS5839-02BA, an ultra-compact chlorine-resistant digital pressure and temperature sensor from TE Connectivity. The sensor is a small digital altimeter operating from 300 up to 1200mbar, optimized for applications where chlorine and saline are present. The sensor is filled with gel, which makes it robust, and enables it to work in harsh environments.
