RTC 11 Click is a compact add-on board that contains a real-time clock IC designed to maximize battery life and reduce overall battery requirements in wearable applications. This board features the AB0815, an ultra-low-power coupled with a highly sophisticated feature set the real-time clock from Abracon LLC.
We provide a library for the RTC11 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.
This library contains API for RTC11 Click driver.
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 );
This is an example that demonstrates the use of the RTC 11 Click board.
The demo application is composed of two sections :
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.

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

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.
