RE: DB48X: HP48-like RPL implementation for DM42
I just wanted to chime in (for once) without reporting an issue...
Instead, I am reporting SPEED! I recently heard of the R47 calculator (variant of the C47 with two shift keys), and made an overlay and keylabel set for it. I thought I would give it a try on my DM42 before applying any overlays or labels, and I was immediately struck by the sluggishness of the calculator (on battery power). Just repeatedly pressing the square root of a number over and over has a very noticeable delay/lag. If you do it fast enough and often enough, you can stop and then wait several seconds for the calculator to catch up. I still remember commenting to c3d a while back when I felt that DB48x was feeling sluggish to me (when dividing 2 numbers with a decimal point (and lots of digits)), and in the next release there was a significant and noticeable difference in speed. (If I recall correctly it was a screen rendering or graphical adjustment.) There's no way for me to go back to the other projects right now (C47) - they just "feel" too slow to me after using DB48x for many months (maybe a year?). I feel like only the stock DM42 firmware is faster from my experience. WP31S/WP34S, WP43/C47, newRPL (various), and DB48X adhesive and tabbed overlays: https://www.hpmuseum.org/forum/thread-20113.html |
