COG is a just a technology for mounting an IC on the LCD glass.
It still has a micro-controller compatible interface. You need to
post a LCD part number and a link to the data sheet, if you want us to
check if CCS has a driver for it. |

Hi...
We want to use Chip On Glass Graphics LCD 128X64, no matter what
ever Controller IC. At least, there should be driver for that
controller IC from CCS.
If you know then can suggest such drivers those are available
with COG manufactured.
We have LCD KS0724 controller IC from Samsung electronics.
Link of Datasheet for that: http://www.ortodoxism.ro/datasheets/SamsungElectronic/mXuytxq.pdf
And its COG module is from CLOVER DISPLAY LTD having model number : CV9007E.
Datasheet for this: http://www.cloverdisplay.com/pdf/cv9007e.pdf
But we don't want to stick with the same. If CCS has a graphics LCD driver
which can be available Chip On Glass Graphics LCD 128X64 model.
No matter what ever is the company....
Please give list of such graphics LCDs...... |

Do you have the compiler ? Look in the c:\Program Files\Picc\Drivers
folder. I found these files there:
SED1335.C --
Example drivers for the SED1335 LCD controller on an Ampire
AG-320240A1 display. (320 x 240)
HDM64GS12.C --
This file contains drivers for using a Hantronix HDM64GS12 with
a KS0108 display controller. The HDM64GS12 is 128 by 64 pixels.
KS0108.C --
This file contains drivers for using a KS0108 LCD controller
for a 64 by 64 pixel display
GLCD.C --
This file contains drivers for using a Hantronix HDM64GS12 with
an LED backlight. The HDM64GS12 is 128 pixles across and 64
pixels down.
graphics.c --
This file contains functions to draw lines, rectangles, bars,
circles and text to a display. |

Hi..
I got PCW and PCH both the CCS compiler.
In 128X64 size, there is HDM64GS12 having controller IC KS0108 but
the problem with that is: it is not Chip On Glass Model.
Do you think any Chip On Glass model is available for KS0108 display
controller? If yes, can we modify HDM64GS12.C file to use for that
COG LCD module and how...?? |

But that's not the way I would do a design. I would pick the best
graphic LCD for the product and write the driver.

If you want to modify a driver to work with a different controller,
then get the data sheets for both controllers. Compare the interface
and the registers. Note the differences and change the driver as required. |
