Click library

  • Author : MikroE Team
  • Date : dec 2019.
  • Type : GPIO type

Software Support

We provide a library for the OPTO4 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 OPTO4 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void opto4_cfg_setup ( opto4_cfg_t *cfg );

  • Initialization function.

    OPTO4_RETVAL opto4_init ( opto4_t ctx, opto4_cfg_t cfg );

  • Click Default Configuration function.

    void opto4_default_cfg ( opto4_t *ctx );

Example key functions :

  • Function for output enable or disable

    void opto4_output_enable( opto4_t *ctx, uint8_t enable );

Examples Description

Opto 4 Click is a galvanically isolated power switch, which uses a power MOSFET in combination with an optocoupler.

The demo application is composed of two sections :

Application Init

Initialization driver init.


void application_init ( void )
{
    log_cfg_t log_cfg;
    opto4_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.

    opto4_cfg_setup( &cfg );
    OPTO4_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    opto4_init( &opto4, &cfg );
}

Application Task

The Output voltage enable and disable every 3 sec.

void application_task ( )
{
    opto4_output_enable( &opto4, OPTO4_OUTPUT_ENABLE );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    opto4_output_enable( &opto4, OPTO4_OUTPUT_DISABLE );
    Delay_ms ( 1000 );
    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.OPTO4

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.
