The upper and lower bounds for your battery voltage should be available on the datasheet. You could just assume the discharge curve is linear, and show the percentage between these bounds in your indicator. A next level take would be to characterize your battery by monitoring the voltage while it discharges. This way you could use the min / max battery voltages as your endpoints, and map the battery voltage to a set of percentages in respect to the total battery life. You could probably do this entirely in the software you already have, or take the battery out and simulate the typical current draw of your device using a resistor (just series/parallell them to get enough wattage capacity).

[@osensiv3sounds978]

Actually for 1s lipos (or liions) the voltage curve compared to % is already known and the difference between different batteries (of the same type) is so low, that you can ignore it. You can look it up on google quite easily and it worked for me just fine. I've also seen some people trying to simplify it into an equation. I tried that, and the results were close enough to be usable. So maybe a software update ? :)

Just to let you know, that problem you had with the rotary encoder is called 'debounce' and you can solve it is software. You basically just need to give the pin some time to settle on a value before registering it as a button press/rotate.

Mapping 2.5V-4.2V to 0-100% shouldn't be too difficult for the battery indicator

[@KingJellyfishII]

it doesn't work quite like that unfortunately, as the voltage is not proportional to the state of charge. you can tell roughly (dead, charged, fully charged) from the voltage but you would be lucky to get a scale from 0-3 let alone 0-100. measuring lithium ion battery state of charge is quite a rabbithole actually.

[@JimnyVR5]

@@KingJellyfishII For LFP I agree with you... for anything else, cell voltage is a good indicator for state of charge

[@KingJellyfishII]

@@JimnyVR5 lfp certainly has an extremely flat discharge curve, but lithium polymer's discharge curve is also quite flat really, and the internal resistance being not insignificant can create a decent error in the predicted state of charge. Maybe I just have a skill issue but I have never got it to work reliably before

[@S.m1cha3l]

(well someone already wrote a better comment talking about this before) Well if you know there voltage when it is connected to a external powersource, run with full battery and when the required voltage is not enough to run the device. You can display an icon for charging, fully charged and nearly empty. Even percentages if you take the delta form those. It could be inaccurate but easier to read But great vid, love it

[@anjithantony6301]

For the battery percentage, just map it from the lowest voltage value of the battery to its highest voltage value, then normalize it to the value 0 - 100%. The equation is like: (measured voltage/highest voltage)*100%. The rest is your field, the percentage bar and what not.

Even though you don't have the rotary encoder doing much right now, it gives you plenty of wiggle room for OS updates down the road. It could be useful for your screen brightness and controlling the direction of the ball in your pool game. Should you be crazy enough to find a place for a small speaker, it could be good for controlling volume, too. If you wanted to get really crafty, you could even override the app behavior for it and use a press+rotate to always control something regardless of what app you're in.

Have you considered using using some ESP32 Forth implementation? Having an interactive, realtime development experience is much more satisfying, than the edit/compile/download/run cycle, even if language is a bit quirky. You might not have display drivers in Forth of the shelf, but you can port existing ones with less effort than you might think, because of the REPL-style development workflow. You can build up convenience words in no time, which makes you application code read really pleasant. I've really enjoyed all the explanation, including the missteps! You are right; those are just as useful to share as the successful steps.

Monitoring the battery voltage and multiplying that to get the charge % is how basically all applications do it. There isn't really another way, it's the only thing the battery can output! You could look up characteristic curves for your battery, or lithiums generally, and it'd probably be pretty accurate. Or else you could monitor it as you discharge it at a representative rate, similar to how much it's discharged through normal use. But a decent guess is likely good enough. Similarly you can't measure a battery's charge while it's charging, because it's voltage, it's internal electrodes, are being raised to to charging voltage. You could perhaps stop charging every minute or so, give the battery a little bit to calm down, then measure it's voltage. I haven't tried that though, and to be honest it sounds flaky, how long does a battery take to settle back to it's normal voltage once you remove the charger? You could perhaps measure charging current going into it, which will reduce as it fills up. Just put a shunt resistor in. That's a proxy for battery charge. Anyway, nice! You ever see the Pine Watch? Some hackers got hold of, what I think are commodity Chinese smartwatches, but they're documented and a couple of people have written OSes for them. Sadly in Python, I'd like to use C myself, but an OS isn't available. I suppose I could write my own, a step at a time. Getting it multitasking sounds like a pain though, lots of opportunities for slow-moving bugs.

[@greenaum]

I would like to see a touch screen, I'd assumed it had one! As for the rotary encoder, debouncing switches has been done in software for ages and I'm sure that includes rotary encoders, computer mice ran off them for decades. There's surely some mature and tested algorithms you can more-or-less just paste in. You went to the effort of the little PCB and all, be nice to get it working. Those capacitors in the circuit diagram just add a little delay to opening and closing, you can do that in code. Is the computer able to give full attention to the encoder? So it doesn't miss steps. Worst-case you could stick a tiny Arduino on there and have it talk over SPI to the main chip.

[@InkboxSoftware]
