I am still reading through all the posts in this topic and others about the GLCD library.
I posted about 2 years ago about compatibility with some displays I have. I think the library then was revision 0.1 and was related to the SED1520.
My displays are EA DIP122-5NLED and are 122x32 and feature a chip which is compatible with the SED1520.http://www.lcd-module.com/eng/pdf/grafik/dip122-5e.pdf
The reason for posting on this topic is the dual display question.
I am building my own version of a home power/energy monitor and I would like it to feature 2 of the displays I have.
I am not sure if anyone has had this working with the SED1520 based displays or not, I still have a bit of reading to do yet.
Tonight I am going to pull the displays out and have a play with them, see if I can get anything working.
I have had the displays for about 3 years but never used them.
Hopefully the GLCD library will work ok with this particular display, it would be nice to utilise the displays.
