Remote control the hp50g.
in [HP48]

From: jibanes on 30 Jul 2010 17:17 List, The HP49g allows [ON]+R as a mean to "remote control" it from a usb host, running (for instance) Samuel Thibault's "HP 49g+ Text Controller" described there: http://www.hpcalc.org/details.php?id=7144 It appears that the HP50g does not support [ON]+R (or is it disabled by default?). Would you know of any similar way to put the calculator in "remote control" mode? Sincerely, Jerome

(Press [ON][S] to turn it off.)

I would be interested in where it's documented, and whether there's any comparable Windows program to interface with it? Is this effected via some ARM code in the internal emulator? Are particular "boot loader" versions required? Thanks for any info. [r->] [OFF]
From: John H Meyers on 30 Jul 2010 19:31 Getting back to the HP49G+ (and perhaps an occasional 50G), might the ability to use a computer's keyboard in place of the calc's (provided ON and R still work on the calc) save a few 49G+ calcs from having to be thrown away when their keyboards fail? Of course, a calc emulator running in the same computer could also make do, in a pinch, but a real calc, still working, could lend more realism to the idea that calculators once existed in real hardware of their own :) [r->] [OFF]

The (lack of) documentation can be found in http://www.hpcalc.org/hp49/docs/programming/masddocs.zip It basically says what I already posted: [ON][R] to turn it on and [ON] [S] to turn it off. That's all there is. |
