Flicker click

FLICKER click is the perfect, simple solution if you need to turn a device on and off at specific time intervals, like blinking LED commercials,alarm system lights, or any other signalling lights.

Click library

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

Software Support

We provide a library for the Flicker 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 Flicker Click driver.

Standard key functions :

• Config Object Initialization function.

  void flicker_cfg_setup ( flicker_cfg_t *cfg );

• Initialization function.

  FLICKER_RETVAL flicker_init ( flicker_t ctx, flicker_cfg_t cfg );

• Click Default Configuration function.

  void flicker_default_cfg ( flicker_t *ctx );

Example key functions :

• Flicker engage function.

  void flicker_engage ( flicker_t *ctx );

Examples Description

This application simple solution if you need to turn a device on and off at specific time intervals.

The demo application is composed of two sections :

Application Init

Initialization driver enables GPIO and also starts write log.

void application_init ( void )
{
    log_cfg_t log_cfg;
    flicker_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.

    flicker_cfg_setup( &cfg );
    FLICKER_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    flicker_init( &flicker, &cfg );
}

Application Task

This example demonstrates capabilities of Flicker Click board.

void application_task ( void )
{
    log_printf( &logger, " *Flicker on!* r/n/" );
    flicker_engage( &flicker );
}  

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.Flicker

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.
