OLED continuous use results.
Well I was amazed how long the test program I provided ran both of the OLED displays. After the 18 hour mark I just decided to let it
run until the batteries depleted. So I have a few things interesting to report. First, when the power dropped to a level that the
program could no longer run, BOTH of the displays simply stopped where they were in the cycle and maintained whatever was on them
at the time the MCU decided to stop running.
Second, when the displays stopped they appeard to be just as brilliantly lit as when
the simulation began. So the power was still more than suffecient to power the displays and the MCU failed first. Kinda neat. If I had
been displaying the time elapsed, the display would show exactly how long they had been going when the MCU stopped crunching. But in this
case I just checked on it from time to time until I saw things had changed.
So I took the battery pack off for about a minute and put it back on. The display showed remnant garbage of the former screen but did
nothing else. The program wasn't running, but some chunk of I2c data was still sent to the displays that was close to the former information
displayed. Hmmm... So I took the batteries off and waited three hours. Put them back on. And the program ran about one cycle and stopped.
So then I had to put a meter on the battery pack. Here's what I got:
6 x AAA batteries after depletion 6 X AAA new batteries
.981 1.617
.982 1.618
.982 1.617
.982 1.616
.983 1.617
.984 1.617
total in series: total in series:
5.89v [on meter] 9.72v [on meter]
Here I also show the data for a fully loaded pack with new batteries data listing. Derive what you will from this test for whatever application
you like - Oh, I almost forgot to give you the total elapsed time... Duh.
total elapsed time:
start time: 01/27/17 @ 0700 hours
stop time: 01/29/17 @ 1613 hours
total hours continuous work: 57 hours 13 minutes
2 days 4 hours 13 minutes.
