Re: Potential for a STM32U5 based DM42
I would consider buying a faster DM42; however, more RAM would make it a must buy for me.

Microscope Reticle Measurement Software
I spend a lot of time measuring things using zoom microscopes equipped with an eyepiece reticle. For zoom scopes this involves a little bit of arithmetic to convert from Reticle units to mm. Some scopes have zoom stops (like 0.625) that make mental arithmetic more error prone that I would like. So I...

Re: The unused top function key
Peet - how many keystrokes you need to start your “reset all“ program? I assume 4: shift-catalog-pgm-myreset (I‘m not DM42 power-programming user, so, still not sure if I correctly understand your use case). Or just press XEQ, which brings up the PGM catalog as well. If you keep the "reset all...

Re: Propagation of Uncertainty Calculations
I'd suggest adding is a PDF copy of the full contents of each document That's a great idea! Turns out it is harder than I expected to make nice PDFs with org-mode -- it's easy to make super ugly ones! After a bit of trial and error, I have PDFs that I'm not ashamed of. I'm not completely satisfied ...

Propagation of Uncertainty Calculations
Greetings; I normally do propagation of uncertainty calculations with Maple; however, I recently found myself at the lab bench while the bench computer was busy with an experiment and my laptop was doing an upgrade. So I coded up a couple computations I needed. Turns out this stuff is handy to have ...

Re: My 42s software collection update
What is the - for on line 17? Can I use this code or is it copyrighted? The ‘-‘ is to drop the stack so that the original y and z are preserved. Feel free to use it, of course! Thank you! Now that I have FUNC, I don't think as much about the stack anymore. BTW, a similar trick allows us to compute ...

My 42s software collection update
I have updated my collection of 42s programs. Reworked everything for free42 3.0.2 Refactored the code to use 10x less RAM. Probably introduced some bugs :( Polynomial roots. Still a couple todo items on this one -- let's call it a beta. Find matrix characteristic polynomial The previous two allow y...
