16 segment Led display would mimic a HP-41 display? - Giuseppe Marullo - 11-11-2009 Hi all, I need some form of output, since I have to mess with led display anyway and I would like something more cool that the expensive serial 5x7 matrices you see today. It seems somewhat easier to find 16 segment instead of 14 segment that should be the most similar used on the 41. Any advice? Giuseppe Marullo
PS: no, I don't plan to emulate a 41 on a fpga, even if...
Re: 16 segment Led display would mimic a HP-41 display? - Lyuka - 11-12-2009 Hi. How about using LiteOn's LTP-4323G (Alphanumeric 16seg. LED display) or LTP-3784G (14seg.) and Maxim's MAX6945 (LED-driver/Key-scanner) ?
However, if its cost won't be a matter, I'd like to use Avago's

>for the feel of former HP's reliable instruments :-) I prefer Leds, but just because of their tolerance to mechanical abuse, VFDs are great.

Re: 16 segment Led display would mimic a HP-41 display? - db (martinez, ca.) - 11-12-2009 Or; there's the form over function approach to LED usage. I think there is enough LED light here to keep even Norm content. Yet i wonder if it will have bugs. And what if i find i want a landscape format or later wish for a "memory lost"?
