are there significant differences in pixel response as battery voltage goes down?
Update: To answer your question, yes apparently the calculator is indeed sensitive to variables such as battery voltage and even possibly/likely the temperature.
I made a couple tweaks to the display layout, but left the core minute pixel timer algorithm alone. Tonight's test shows it's already off by a minute after only 25 minutes of running.
Oh well, it's still a fun experiment, even though I was already aware I might be playing with digital fire with this silly project. ๐คทโโ๏ธ
Very good question!
At this moment I don't know for sure.
I've only been running it on consistent 5V USB power until yesterday.
I am keeping the voltage level question in mind though...
Welp, one of my 4 batteries died today (no worries on the memory on this model). I found a spare battery, but between that and switching back and forth to USB power, it does seem the calculator's speed might be lightly affected by voltage levels and even possibly by temperature.
Hey, ain't nothing perfect...
I guess it doesn't matter since you can't look at it with a dead battery anyway.
It doesn't even need batteries, it can run directly from USB power with no batteries, but that doesn't answer any questions of how or if voltage levels affect instruction or pixel timing.
