Press and hold the SHIFT key while pressing ▲ or ▼ in order to execute BST or SST respectively when in alpha input mode. Un-shifted R/S still behaves as usual allowing program execution to resume after inputting alpha data to a program.įunction arguments (eg. Free42: Use the convert menu it is possible to convert degrees to radians (and back), then hours-minutes-seconds (and back), but no 400 degrees conversion, for that surely routines exists Using variables The 506w has some single letter variables (or better, registers). Local labels LBL A and LBL a and global labels LBL "ABC", LBL "123" and LBL "A123" work as expected. Two-digit local labels LBL 01 are not available. Switch to standard HP-42S mode to get them.

Im using an Arduino Pro Mini, 328P, 3. Shifted R/S gives '?' instead of entering/leaving Prgm mode.ĪSTO, ARCL, '%', 'pi' and 'E' (exponent) are not available. Im making an altitude recorder to go in a model rocket, so Im trying to reduce weight as much as possible. While celebrated for its overall success, Finland had a gender gap. Shifted ÷, ×, - and + give '÷', '×', '-' and '+' instead of the alpha characters. Finlands tertiary Education has moreover been ranked first by the World Economic Forum. SHIFT 0 (zero) to SHIFT 9 give the digits 0-9 instead of the alpha characters. SHIFT A to SHIFT O give the same characters. The function keys still allow input in HP-42S mode.Īll alpha keys A-Z give the expected characters.

Flashing QSPI using dm_tool (obsolete)Ĭase made from stainless steel, matte black Physical Vapour Deposition (PVD) coated and laser engraved This is similar to the DM42 virtual variables ResX and ResY, but can be used in programs that automatically adjust the graphic output to the display resolution when running on DM42, Free42 or Plus42. On the DM42, the new Free42 functions WIDTH and HEIGHT return values that are matching the current display mode as selected by the GrMod virtual variable, e.g. I still have the 48G but it has an annoying issue that seems to doom most of them - apparently some rubber parts inside the calculator decay and eventually you can’t turn it on. Added much additional help file content created by Didier Lachieze, adding many function details, an alpha- index, notes on recent Free42 extensions and more. In engineering school, I loaned my HP 28S to a friend and he lost it, so it was replaced by an HP 48G.Fix: Stack layout XYZTA & NSTK & CLST (report Stack layout XYZTA & NSTK & CLST).Fix: INTEG_ down (report Reproducible DM42v3.21/DCMPv3.23 Crash Report).WIDTH/HEIGHT returns current graphics mode resolution.Fix: Crash in SHOW (report Reproducible crash on version 3.21/3.0.9a).Base mode automatically set to decimal upon entering PRGM mode.A…F added as programmable function (in BASE menu).xls from FHCE MISC at University Of Georgia.
