Definition of the 1
st
Example -
Simple Raspberry Pi® ON/OFF Schedule executed
1 time for
1 minutes and repeated every day
We need to start up - set ON -
the Raspberry Pi® at 10:00 (date for the
first-time start-up is
20
th
August 2017). The Raspberry Pi
® will run for 1 minute
(executing their tasks), then system
will shut down. Next day the above Sequence (has only one Action) will be repeated. Please
check below settings to understand exactly and properly the meaning of the
ETR SAS
vocabulary. Involved Registers and programmed values for this example are the following:
0x6A -> UPS PIco Hardware RTC Registers Direct Access
Not needed. Can be used just for monitoring or any other application.
0x6B -> UPS PIco 0x16 SAS Selection Register
SAS_number
= 0x00;
means it will use for that Schedule the SAS0
0x6B -> UPS PIco 0x17 SAS RUN Register
SAS_RUN
= 0x00;
during programming phase and then must be set to
0x01 to make ETR SAS running
0x6B -> UPS PIco 0x19 Time Scheduler Selector
