(50g) Battery Voltage - 2old2randr - 2025-02-16 02:30 AM

Attached is a tiny program that reports the battery voltage on a physical HP 50g. Note that this works only on the 50g and will not report correct results on an HP 49g+ since the scaling from the value reported to a voltage is different (max 4.5V instead of 6V). The improvement is trivial but I don't have access to an HP 49g+ to do it myself.

To use, unzip the attachment and copy BVolt.hp to your calculator and run it. The battery voltage and comment (Good/ Charge/ Bad) will be displayed in the top status line.

The attached zip file contains:
1. BVolt.hp: Compiled program. When placed on the stack, it has a checksum of #C46Bh and a size of 219 bytes.
2. Battery.s: Source code - can be compiled with MASD on the calculator itself.
