Need a BS2 sample code for a 64 x 240 parallel Graphic LCD.
Does anyone have any idea were to get it?
Thanks.

Here is a website with an entire section dedicated to the Toshiba T6963C
controller:
[noparse][[/noparse] http://ourworld.compuserve.com/homepages/steve_lawther/t6963c.htm ]
The chip apparently has two basic modes: Text and Graphics.
As far as the Stamp is concernd, it it viewed like any other parallal LCD
in Text mode,
and in Graphics mode, it can be viewed as though it were a Hantronix unit
with the same controller. On the Hantronix site, look at:
[noparse][[/noparse] http://www.hantronix.com/app-note.htm ]
From that site, you can download the follwoing PDF document
[noparse][[/noparse] ftp://wfp62508.w1.com/t6963app.pdf ]
This PDF shows the wiring and hardware requirements for connecting the
T6963C controller to the Graphics module. Unfortunately, the applications
information given there is for the 80C51 microprocessor, so those specifics
need to be ignored. This information is apparently FAR BETTER thant the
original Toshiba documention, which is said to me nearly unreadable.
One Page 3 of that data sheet, a flowchart is offered, which should provide
all the clues necessary for developing a routine for any microcontoller,
including the Stamp. It should be noted at this juncture, that 13 control
and data pins are required for its operation:
D0-D7, WR, RD, CE, CD and RESET
Thus a fair portion of the available Stamp puins are required for operation
of this device.
Without the use of a bit of electronics "trickery" that's an awful lot of
Stamp resources to be dedicated to any device. Just my opinion.
Additional information can probably be found at:
[noparse][[/noparse] http://www.eio.com/public/lcd/ ]
which is a public message board, the same as this one, but specifically
dedicated to ALL LCDs; their use, applications, hints, suggestions, etc,
and thousands of microcontroller and computer uses worldwide.
Hope that gets you started.
