About this app

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 HP48 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 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.

'Emu48 for Android' is an Android program which emulates several HP calculators, including the HP 48GX, on Android. It is independently developed (not developed by Drehersoft) and is a separate program from 'Droid48 Reader'. 'Emu48 for Android' is available on Google Play.

When using 'Droid48 Reader' with 'Emu48 for Android', it is important to first use the Save As... menu in 'Emu48 for Android'. This saves its data using the standard Android UI. After doing this, return to 'Droid48 Reader', select Open File from the menu, and navigate to where the data was just saved to.

Note that 'Emu48 for Android' also has the built in ability to save data. Put the data into level 1 of the stack and use the Save Object... menu. This works for any data that can be put on the stack.

This app is a must for Droid48 Users. It allows a user to backup data from Droid48 for archiving, sharing or even transfer to a real HP48S,SX,G,GX or G+! Work on the calculator should always be archived as the emulator, like the real calculator is subject to crashing. All of the HOME directory should be backed up. Use a name built of of today's date such as :5:AUG1217.D48 and execute ARCHIVE. This name tells when the archive was made. Click menu, Save Memory State. Start the Reader. (Make sure show hidden structures is on.) Since the name was tagged with 5 the archive is in Port 5 so click that icon. Long press AUG1217.D48. This will recall the HOME directory as a Backup object. Navigate to where you want to save it, adjust the filename and click SAVE. To recover, from Droid48 click Put program on stack, navigate to the directory (folder) where the archive is and click it. Backup AUG1217.D48 will appear. Execute RESTORE. Tap ON a few times and you are back in business. Oct 2018: Updated to work on Android Pie
