Software Support
Software Support
We provide a library for the RTC 21 Click Board™ as well as a demo application (example), developed using MikroE compilers. The demo can run on all the main MikroE development boards.
The package can be downloaded/installed directly from NECTO Studio The package Manager (recommended), downloaded from our LibStock™ or found on MikroE Github account.
Library Description
This library contains API for the RTC 21 Click Board™ driver.
Key functions
-
rtc21_set_timeThis function sets the starting time values - second, minute and hour. -
rtc21_set_dateThis function sets the starting date values - day of week, day, month and year. -
rtc21_read_timeThis function reads the current time values - second, minute and hour.
Example Description
This example demonstrates the use of the RTC 21 Click Board™ by reading and displaying the time and date values.
void application_task ( void )
{
if ( RTC21_OK == rtc21_read_time ( &rtc21, &time ) )
{
log_printf( &logger, " Time: %.2u:%.2u:%.2urn",
( uint16_t ) time.hour, ( uint16_t ) time.minute, ( uint16_t ) time.second );
}
if ( RTC21_OK == rtc21_read_date ( &rtc21, &date ) )
{
log_printf( &logger, " Date: %s, %.2u.%.2u.20%.2u.rn",
rtc21_get_day_of_week_name ( date.day_of_week ),
( uint16_t ) date.day, ( uint16_t ) date.month, ( uint16_t ) date.year );
}
Delay_ms ( 1000 );
}
The full application code, and ready to use projects can be installed directly from NECTO Studio The package Manager (recommended), downloaded from our LibStock™ or found on MikroE Github account.
Other MikroE Libraries used in the example:
- MikroSDK.Board
- MikroSDK.Log
- Click.RTC21
Additional Notes and Information
Depending on the development board you are using, you may need USB UART Click Board™, 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. A UART terminal is available in all MikroE compilers.
MIKROSDK
The RTC 21 Click Board™ is supported with mikroSDK - MikroE Software Development Kit. To ensure proper operation of mikroSDK compliant Click board™ demo applications, mikroSDK should be downloaded from LibStock and installed for the compiler you are using.
