My WP34s projects

Macro

WP34s software package already includes assembler/preprocessor. However, it

insists on very strict and not at all intuiltive ASCII opcode input
does not allow "local symbols" of the form 1H, 2H, etc. (unsurprisingly)

So, I had to modify my HP35s assembler for the WP34s. Here is the link: nsg_pp.zip

Custom builds

WP34s firmware has several compile time selectable options which I found useful. Since they are options and not included in standard build, I have to make my own custom build and keep it up to date. (since I do not have a device without crystal, I do not make a build for barebones device)

calc_xtal -- firmware with crystal oscillator enabled
calc_ir -- firmware with IR printing enabled

The included options are:

INCLUDE_YREG_CODE (y-register display)
MODIFY_K62_E3_SWITCH (h ./, in DECM mode switches E3 separator on/off)
MODIFY_BEG_SSIZE8 (BEG annunciator indicates stack size)
DEFAULT_DATEMODE 1 (default setting for date mode is Y.MD)
NO_DATEMODE_INDICATION (there is no indication in status line when date mode is different from default)

Documentation

I have prepared pocket sized consize reference for WP34s. Please check it out.

My hardware modifications

The first WP 34S I modified all by myself (Harald Pott's board and crystall)

My Programs

Clock

clock.wp34s is a program that constantly displays current time. Additionaly, it can place this time on stack and provides helper subroutines for time recall and timestamp arithmetic.
