| uint32_t RtcClass::getRtcSeconds |
( |
| ) |
|
Get seconds from RTC.
- Return values
-
| uint32_t | Quantity of seconds since epoch |

-
| bool RtcClass::setRtcSeconds |
( |
uint32_t |
seconds | ) |
|
Set RTC.
- Parameters
-
| seconds | Quantity of seconds since epoch |
- Return values
-
- Note
- Updates RTC NVRAM
Quantity of RTC cycles since last update.
Magic ID used to identify that RTC has been initialised.
Global instance of real time clock object.
- Note
- Use RTC.function to access real time clock functions
-
Example:
1 RTC.setRtcSeconds(1454225610); //set time to 07:33:30 2016-31-01
