WP 34S Version 3.2
This is firmware for the WP 34S calculator. This is for HP's 20b
and 30b hardware. The present version is the first we believe is
mostly bug free. We provide ROM files for use on the real hardware
and emulation software running on the PC (see below).
Programs can be written on the PC and translated to binary form with
the tools contained in the tools directory. A separate manual is
provided. Software and data can be transfered to the device with the
same cable that is used to update the firmware.
Highlights of this release
* Dynamic allocation of memory to registers, program and subroutine
* Local registers and flags,
* Much improved handling of libraries in flash memory,
* Matrices with up to 100 elements,
* Separate statistical accumulators some of which stored in higher
precision for greater accuracy,
* Increased accuracy for some mathematical functions,
* Double precision mode, allows user programs to implement fully
* Printing to an HP 82240A/B IR printer,
* Even more functions.
You will need a special programming cable and the MySamba software
to reflash an HP 20b or 30b. See the folder FlashTool on our SourceForge
pages where you found this file. For the time being, access to a PC
running Windows is required for flashing.
The classic emulator needs at least Windows(r) XP. Its PC keyboard to
calculator keyboard mapping isn't entirely obvious.
The newer Qt based emulators work on various platforms, including W2K. They
will eventually replace the one contained in the emulator directory in the
distribution archive. They also have a revised keyboard mapping.
The displayed revision numbers in the VERS screen may differ between the
manual, the flash image and the emulator(s).
