RTC 11 Click

RTC 11 Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.

Software Support

Example Description

This is an example that demonstrates the use of the RTC 11 Click board.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.RTC11

Example Key Functions

• rtc11_cfg_setup Config Object Initialization function.

void rtc11_cfg_setup ( rtc11_cfg_t *cfg );

• rtc11_init Initialization function.

err_t rtc11_init ( rtc11_t *ctx, rtc11_cfg_t *cfg );

• rtc11_set_time Set time hours, minutes and seconds function

err_t rtc11_set_time ( rtc11_t *ctx, rtc11_time_t rtc_time );

• rtc11_get_time Get time hours, minutes and seconds function

void rtc11_get_time ( rtc11_t *ctx, rtc11_time_t *rtc_time );

• rtc11_set_date Set date day of the week, day, month and year function

err_t rtc11_set_date ( rtc11_t *ctx, rtc11_date_t rtc_date );

Application Init

Initalizes SPI, performs software reset, sets system time and date, and starts clocking system.

void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    rtc11_cfg_t rtc11_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.

    rtc11_cfg_setup( &rtc11_cfg );
    RTC11_MAP_MIKROBUS( rtc11_cfg, MIKROBUS_POSITION_RTC11 );
    err_t init_flag  = rtc11_init( &rtc11, &rtc11_cfg );
    if ( SPI_MASTER_ERROR == init_flag ) {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );

        for ( ; ; );
    }

    log_printf( &logger," Setting time: %.2d:%.2d:%.2d \r\n", ( uint16_t ) time.hours, ( uint16_t ) time.min, ( uint16_t ) time.sec );

    log_printf( &logger," Setting date: %.2d/%.2d/%.2d \r\n", ( uint16_t ) date.day, ( uint16_t ) date.month, ( uint16_t ) date.year );

    log_info( &logger, " Application Task " );
    log_printf( &logger,"------------------------\r\n" );
}

Application Task

Demonstrates use of RTC 11 Click board by reading and displaying time and date via USART terminal.

void application_task ( void ) 
{
    rtc11_get_time ( &rtc11, &time );
    Delay_ms ( 10 );
    rtc11_get_date ( &rtc11, &date );
    Delay_ms ( 10 );
    
    if ( sec_flag != time.sec ) {
        log_printf( &logger, " Date: " );
        disp_day_of_the_week( date.day_of_week );
        log_printf( &logger, " %.2d/%.2d/20%.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" );
    }
    sec_flag = time.sec;
}

Application Output

This Click board can be interfaced and monitored in two ways:

• Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
• UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
