RTC 13 Click is a compact add-on board that accurately keeps the time of a day. This board features the PCF2123, an SPI configurable real-time clock/calendar optimized for low power operations from NXP Semiconductors. The PCF2123 provides year, month, day, weekday, hours, minutes, and seconds based on a 32.768kHz quartz crystal. Data is transferred serially via an SPI interface with a maximum data rate of 6.25 Mbit/s. An alarm and timer function is also available, providing the possibility to generate a wake-up signal on an interrupt line, in addition to a programmable square-wave clock output. This Click board™ is suitable for various time-keeping applications, including high-duration timers, metering, daily alarms, low standby power applications, and many more.

Click library

  • Author : Nenad Filipovic
  • Date : Jul 2021.
  • Type : SPI type

Software Support

We provide a library for the RTC13 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 from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for RTC13 Click driver.

Standard key functions :

  • rtc13_cfg_setup Config Object Initialization function.

    void rtc13_cfg_setup ( rtc13_cfg_t *cfg );
  • rtc13_init Initialization function.

    err_t rtc13_init ( rtc13_t *ctx, rtc13_cfg_t *cfg );
  • rtc13_default_cfg Click Default Configuration function.

    err_t rtc13_default_cfg ( rtc13_t *ctx );

Example key functions :

  • rtc13_get_time RTC 13 get time function.

    err_t rtc13_get_time ( rtc13_t *ctx, rtc13_time_t *rtc_time );
  • rtc13_set_time RTC 13 set time function.

    err_t rtc13_set_time ( rtc13_t *ctx, rtc13_time_t rtc_time );
  • rtc13_get_date RTC 13 get date function.

    err_t rtc13_get_date ( rtc13_t *ctx, rtc13_date_t *rtc_date );

Example Description

This is an example that demonstrates the use of the RTC 13 Click board™.

The demo application is composed of two sections :

Application Init

Initialization of SPI module, log UART and additional pins. After driver initialization and default settings, the app set the time to 23:59:50 and set the date to 04.08.2021.


void application_init ( void )
{
    log_cfg_t log_cfg;      /**< Logger config object. */
    rtc13_cfg_t rtc13_cfg;  /**< Click config object. */

    /** 
     * 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.

    rtc13_cfg_setup( &rtc13_cfg );
    RTC13_MAP_MIKROBUS( rtc13_cfg, MIKROBUS_1 );
    err_t init_flag  = rtc13_init( &rtc13, &rtc13_cfg );
    if ( SPI_MASTER_ERROR == init_flag )
    {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );

        for ( ; ; );
    }

    rtc13_default_cfg ( &rtc13 );
    log_info( &logger, " Application Task " );
    Delay_ms ( 100 );

    date.weekday = 3;
    date.day = 4;
    date.month = 8;
    date.year = 21;
    rtc13_set_date( &rtc13, date );
    Delay_ms ( 100 );

    time.hours = 23;
    time.min = 59;
    time.sec = 50;
    rtc13_set_time( &rtc13, time );
    Delay_ms ( 100 );
}

Application Task

This is an example that shows the use of a RTC 13 Click board™. In this example, we read and display the current time and date, which we also previously set. Results are being sent to the Usart Terminal where you can track their changes. All data logs write on USB changes every 1 sec.


void application_task ( void )
{  
    rtc13_get_time( &rtc13, &time );
    Delay_ms ( 1 );
    rtc13_get_date( &rtc13, &date );
    Delay_ms ( 1 );

    if ( time.sec != new_sec ) 
    {
        log_printf( &logger, "  Date      : %.2d-%.2d-%.2d\r\n", ( uint16_t ) date.day, ( uint16_t ) date.month, ( uint16_t ) date.year );
        log_printf( &logger, "  Time      : %.2d:%.2d:%.2d\r\n", ( uint16_t ) time.hours, ( uint16_t ) time.min, ( uint16_t ) time.sec );
        log_printf( &logger, "- - - - - - - - - - - -\r\n" );
        new_sec = time.sec;
        Delay_ms ( 1 );
     }
}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.RTC13

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.
