PIC 16C84 code for the Epson SED1200 chip in the EA-C20017AR modules

Here is the PIC 16C84 code lcd.inc for driving the SED1200 LCD display as used in the Epson EA-C20017AR modules. The SED1200 data sheet is available from the Epson Web Site the Epson Web Site . , or this is what I downloaded sed1200f.pdf or m1200.pdf

Thanks to michael.gaus@ngi.de , here is a scanned sheet for the modules: ea-x_series.pdf. ( 556k bytes). It does however have some interesting information about the EA-C series modules as well.

;The Epson EA-C20017AR display uses a SED1200F controller.

I brought some of these displays from Greenweld Electronics. They were cheap, but have a good character set, and only require 7 data lines.
