PG12232-A

[Justin James Clayden]

Hey bit-twiddlers,

I'm looking for docs for the 'Powertip' PG12232-A LCD. No, not the single
page pinout spec sheet, but info on how to talk to the thing with a micro.

Cheers,
Justin

Have you seen the SED docs??

Find out from the distributors whether the on-board controller is a T6963C
or one of the SED controllers (and which one), or their eqivalent. The single
sheet datasheet doesn't indicate what it is. Once you find that info, then
obtaining datasheets for the chips shouldn't pose too much of a problem.
Examples that use the Toshiba T6963C are on the net.

speak for yourself..

Oh, I do.

micro.

Not knowing exactly what type of display the PG12232 is, i can offer you a
great deal of help.

It's a 122*32 dot matrix display with the same pins as a char. LCD, plus two
'Chip Select' lines, which seem to need to be either 1,0 or 0,1.. plus
there's an external clock input.

However, if its a character LCD, most of these use the

same interface (hitachi perhaps) so any decent doco from any char lcd
manufacturer should help you out. Seiko used to be quite good. Now if it is
a graphics LCD, then most of these have an onboard driver these days,

I'm aware of the low-level driver that sends voltages to the LCD itself, but
do you mean a higher-level driver that accepts lovely simple commands like
'plot a point at }{x,y}?

either

a toshiba driver or ...someother driver, in which case you must seek out the
driver chip manufacturer for details on the operation.

I've spoken to 'Powertip', the manufacturers, but even they aren't much
help. The PG12232-A is on *their* website and they still can't find the
docs!
