Just an idea.. In true Russian style why not construct a complete new
display from dot matrix LED modules. Totally impractical I know, but oh so
typically Russian.
Using only my steel dentures and solder reclaimed from stolen military
electronics, melted over an open fire?
I'm looking for a drop-in replacement (more or less) for an existing
circuit, where I can just wire it up, change a string table, and be on
my way. If I'm going to have to go to significant trouble, then I'll
just use a graphic LCD.
Exec. You know, for some reason I thought that the Hitachi interface
allowed the whole character set to be reprogrammed on the fly.
I'm aware of LCD controllers that offer a RAM-resident CG set for the
whole font table, but I've never seen one in the wild (probably
because it would waste so much ROM space in the host side of the
equation). All the standard controllers only let you redefine a few
characters, typically 16; the remainder are mask-ROM and you're given
the option of a custom mask run.
Is it possible to redefine a character, print it, and then redefine again.
No, the controller doesn't work that way. It's not like UDGs on the
Spectrum (are you the same Aly as in c.s.s?) which are really just a
fancy way of accessing a fully APA display.
