Rudi, have you seen the C43 project from Jaymos (if not, see the thread " 43S Alternative key layout --> WP43C")? Pretty nice to get a taste of WP43s on unmodified and unaugmented original DM42 hardware. Walter: for what it's worth I found the updated manual clear. My only remarks would be...

Hi, My understanding is that the DM42 has 1MB of internal flash on the STM32L476Z chip and 8MB of external flash available via QSPI (2MB mapped at 0x90000000 and used as an extension to internal flash and 6MB used to expose a virtual USB FAT disk). However, https://technical.swissmicros.com/dm42/doc...

I have been spending some time understanding the wp43s codebase. I'm making good progress, but one thing that's stumping me is understanding the design rationale for storing certain things in QSPI. I do understand the TO_QSPI macro is forcing things into the .qspi section which will then end up into...

I ran into the same issue and built the 107 version with the L42 layout. I just put it on Github for your convenience, you can find it here: https://github.com/semi-simple/C43-mirr ... -fixed.pgm

Same here: I've got HP's true leather cases for Pioneers and Voyagers. They are the best you can get for these calculators. Would you mind providing a picture as well? I would love to know what these used to look like and, surprisingly I find it difficult to find information about those. Do they ha...

To close the loop on this thread: the latest firmware does now include Free42 3.02: viewtopic.php?p=19930#p19930

It does seem wise to avoid log / Log given the possible ambiguities indeed!

(Nitpicky remark: LG is identical to LOG10 like LN being identical to LOGe and LB to LOG2. Never let any mathematician catch you with a naked LOG in your text!) I think pure mathematicians tend to assume \(\log\) means \(\log_e\) because they don't have a lot of use for \(\log_{10}\). Yes. In fact,...

Ok, I get it now, thanks all. I had not realized this could NOT be a feature on a RPN calculator, as it seems painful.

I am glad that Free42 (in all its modes), WP43s and C43 all have automatic stack lift, always. These projects are all in good hands.

Free42 is type alpha (Classical RPN and 4 levels stack) by default and can optionally be type delta (classical RPN and ~unlimited stack). I'm not sure introducing new terminology just for describing this is going to reduce confusion very much. Free42 in NSTK mode looks more like "type beta&quo...
