Click library

  • Author : MikroE Team
  • Date : Jan 2020.
  • Type : SPI type

Software Support

We provide a library for the Rtc5 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 Rtc5 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void rtc5_cfg_setup ( rtc5_cfg_t *cfg );

  • Initialization function.

    RTC5_RETVAL rtc5_init ( rtc5_t ctx, rtc5_cfg_t cfg );

  • Click Default Configuration function.

    void rtc5_default_cfg ( rtc5_t *ctx );

Example key functions :

  • Set time hours, minutes and seconds function.

    void rtc5_set_time ( rtc5_t *ctx, uint8_t time_hours, uint8_t time_min, uint8_t time_sec );

  • Set date hours, minutes and seconds function.

    void rtc5_set_date ( rtc5_t *ctx, uint8_t date_day, uint8_t date_month, uint16_t date_year );

  • Get time and date function.

    void rtc5_get_time_and_date ( rtc5_t ctx, rtc5_timedate_t timedate_data );

Examples Description

This is a example which demonstrates the use of RTC 5 Click board.

The demo application is composed of two sections :

Application Init

Initializes GPIO, SPI and LOG structures, sets CS pin as output and INT pin as input. Initialization driver enable's - SPI, clear RTCC and SRAM memory, sets starting time and date, enable counting and start write log.


void application_init ( void )
{
    log_cfg_t log_cfg;
    rtc5_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_printf( &logger, "- Application Init -\r\n" );

    //  Click initialization.

    rtc5_cfg_setup( &cfg );
    RTC5_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    rtc5_init( &rtc5, &cfg );

    rtc5_default_cfg ( &rtc5);
    Delay_ms ( 100 );

    rtc5_clear( &rtc5 );
    Delay_ms ( 100 );

    time_sec_new = 255;

    // Set Time: 17h, 59 min and 50 sec
    rtc5_set_time( &rtc5, 23, 59, 50 );

    // Set Day of the week : Wednesday
    rtc5_set_day_of_the_week( &rtc5, RTC5_DAY_OF_THE_WEEK_TUESDAY );

    // Set Date: 31 ( day ), 12 ( month ) and 2019 ( year )
    rtc5_set_date( &rtc5, 31, 12, 2019 );

    // Start counting
    rtc5_set_counting( &rtc5, 1 );
    Delay_ms ( 100 );

    log_printf( &logger, "--------------------\r\n" );
    log_printf( &logger, "    RTC 5  Click    \r\n" );
    log_printf( &logger, "--------------------\r\n" );

}

Application Task

RTC 5 Click communicates with register via SPI by write to register and read from register, display RTC time and date.


void application_task ( void )
{
    rtc5_get_time_and_date( &rtc5, &time_date_data );

    if ( time_sec_new != time_date_data.sec )
    {
        log_printf( &logger, " Time : %02d:%02d:%02d\r\n", time_date_data.hours, time_date_data.min, time_date_data.sec );

        display_log_day_of_the_week( time_date_data.w_day );

        log_printf( &logger, " Date : %02d.%02d.20%02d.\r\n", time_date_data.day, time_date_data.month, time_date_data.year );
        log_printf( &logger, "--------------------\r\n" );

        time_sec_new = time_date_data.sec;
    }
} 

Note

Additional Functions: void display_log_day_of_the_week( uint8_t w_day ) - Write day of the week log.

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.Rtc5

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.
