Droid48 Reader

Droid48 Reader is used to:

• Read HP 48-Series calculator files
• Read data from Emu48 for Android, a separate HP 48 calculator emulator
• Read data from Droid48, a separate HP 48 calculator emulator
• Easily navigate through the data
• Save or share portions as files.
• PNG support: HP48 graphics are convertible to standard PNG files

For example, if a user were to write a new program inside of Emu48 for Android or Droid48, the user can then use Droid48 Reader to extract this program as a stand-alone file onto their SD card. From here, the user can do whatever they normally would do with this file such as simply store the program for archival purposes, download this file into a real HP 48 calculator, share it with a friend to load into their own Emu48 for Android or Droid48, or post it on the Internet at sites like http://www.hpcalc.org (note: these are beyond the scope of Droid48 Reader).

As another example, the user can read a large stand-alone file that is an HP 48 directory file, navigate to an algebraic equation, then share this algebraic equation via email (requires a separate Android email program that supports sharing).

A stand-alone HP 48 file is a file for the Hewlett-Packard 48-series of calculators (ex: HP 48S, 48SX, 48G, 48G+, and 48GX). More can be read on these calculators on Wikipedia.
