DB48X: HP48-like RPL implementation for DM42

I have DB48 'working' now, HOWEVER,

The XEQ key does not allow me to key in text. The cursor changes to 'A' which indicates I should be in text entry mode, but I cannot enter text - ie hitting the '4' key yields a 4 rather than a T.????

The 'A' in the cursor does not indicate "alpha" but "algebraic". The "alpha" mode is indicated by the cursor turning white, and an "ABC" or "abc" indicator showing up in the header.

The "auto alpha" mode for XEQ was removed when I introduced "transient alpha". See https://github.com/c3d/DB48X-on-DM42/blo...nteraction.

Essentially, you have three ways to enter alpha mode:

1/ Shift Enter, which is a three-way toggle: [ ] -> [ABC] -> [abc]
2/ Long press on the shift key. This only enables [ABC], can't do lowercase that way.
3/ Transient alpha, where you hold the up(left) or down(right) key and quickly type an alpha key (after that, you can type the rest more slowly). If you don't type another key within 0.5s, the left/right function is activated.

Quote:Also, not a bug, but a preference - the stack number levels on the left side are very small - can these be made larger?

Not at the moment. I can make this a future option. They used to be larger, but I thought this was a waste of screen space.

So you need to run the "Load QSPI from FAT" entry before loading the .pgm file (or .pg5 for the DM32). However, that QSPI file should allow you to also run the DM42 program.


The same "Setup" key (shift 0) gives you a slightly different menu, notably because it direclty contains a "5. Load Program" which lets you load the DM42 program directly.

Note that when you switch programs like this, the calculator state will be lost. So you should save the DM42 state before loading another program (using the same menu), and reload it after you return to DM42.

Switching back and forth between DM42 and DB48X takes less than one minute. I recommend doing it while on USB power, because flashing is likely to consume more power than other calculator operations.
