Hi, the manual here:
http://www.matrixorbital.ca/manuals/GLK ... SM_110.pdf
says that modifications need to be done in order to get this lcd to work via i2c. THe problem is that the image in that manual which should display the changes needed actually doesn't show up for me [i tried xpdf, evince (linux) and adobe acrobat (windows)].
Can anyone give me a screenshot or photo of what i need to do?
Thanks,
Alex
i2c glk12232-25-sm rev 1.2 [how to]
Hi Alex,
Good to see you are thinking of experimenting with your GLK12232-25-SM in I2C mode, sorry you've had so much trouble finding that image. It is actually not there in the document itself, so your programs may be working fine, however, you are unable to view the image.
This display is so very old, I had hard time finding the image in our archives, but I've got something that I think will outline the changes sufficiently.
Please note that this unit has been superseded twice now, and it is recommended that if you are developing an application with this product, that the newest revision, 2.0, be used.
If you have any further questions regarding that image, or your display, please let me know.
Thanks,
Troy

Hi,
I also have to work with this old LCD display and I also have to modify it to use I2C. But the above image ist not identical with my LCD (R1.2) at #2. I have there a resistor, but I don't think, that I have to remove it. I can open a connection a bit lower. Can someone confirm that?
Thanks a lot.
