Smarter Battery Checker

(account deleted) 10 Aug 2019 22:54

The provided assembly code that checks the level from the Hex Codes page that checks the battery from 0-4 works fine, but is there a possibility that a checker can be made that checks from 1-100%? Or is it not possible?

I’m fairly certain it isn’t possible. The way the 83 checks its battery level is in a binary fashion where there is only “good” or “bad”. The 84 checks in a way which allows for four discrete levels corresponding to each 25% of the battery. If I am not mistaken, the way the OS handles this is using only two bits. While there has to be some function that sets those bits, changing it would require modifying the OS.

If you really were that concerned about it, there is probably some hardware workaround where you could use the I/O port, but at that point its easier just to use a voltmeter anyways.

The voltmeter is the yellow thing with the + and - wires that shows how many volts are left put of 1.5v? If so, I think my dad has one in the garage

That's too bad that it only does 0-4. Man you guys seem to know a LOT with calculators, I wish I was that smart as ya

There are many different forms of voltmeter, but yes, that is the general concept. It just measures the voltage difference between two points.
