What's the fine print on the chips on your LCD module?

A quick google of SG12864A brought me to me LCD and it shows using HD61202. Now do a search for HD61202 in the library and see if you can do a driver. You may have to do some work,... ie; you may have to convert a different graphic LCD driver to match you spec.
