Library Description

Library is used to get gmt time and local time by calculating data from data registers. Library communicates with the device via I2C driver and driver functions. Library offers a choice to get time data in two formats, 12 hours format and 24 hours format. For more details check documentation.

Key functions:

  • uint8_t rtc7_writeReg( uint8_t register_address, uint8_t transfer_data ) - Function writes one byte data to the register.
  • uint8_t rtc7_readReg( uint8_t register_address, uint8_t nBytes, uint8_t *dataOut ) - Function reads the desired number of bytes from the register/s.
  • void rtc7_getGmtTime( rtc7_time_t *gmt_time ) - Function gets the gmt time data in both time formats.
  • void rtc7_getLocalTime( rtc7_time_t *local_time ) - Function gets the local time data including the determined time zone in calculations.

Examples description

The application is composed of three sections :

  • System Initialization - Initializes peripherals and pins.
  • Application Initialization - Initializes I2C driver and after the reset function configures the device to works in 12 hours time format with desired input and output frequency. After that allows the timer and the oscillator to be enabled.
  • Application Task - (code snippet) - Waits until device be stable and logs time after each second.
void applicationTask()
{
    rtc7_getLocalTime( &timeDate );
    
    if (checkYear == 0)
    {
        mikrobus_logWrite( "Wait...", _LOG_LINE );
        while ((timeDate.year != timeSet.year) && (timeDate.year != (timeSet.year + 1)) && (timeDate.year != (timeSet.year - 1)))
        {
            rtc7_getLocalTime( &timeDate );
        }
        mikrobus_logWrite( "", _LOG_LINE );
        checkYear = 1;
    }
    
    if (checkChange != timeDate.seconds)
    {
        rtc7_displayResults();
        checkChange = timeDate.seconds;
    }
}

Additional Functions :

  • void rtc7_displayResults() - Logs time results in the appropriate format on UART.

Other mikroE Libraries used in the example:

  • Conversions
  • I2C
  • UART

Additional notes and informations

Depending on the development board you are using, you may need USB UART clickUSB 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.
