Hi folks, Quick question (maybe). I'm trying to drop in a surplus replacement LCD display (1x16 hd44780 controller) into an existing PIC project, and I'm having a problem. The original display (a densitron lm2015) works fine, but the new display (noname, but suposedly supertwist) only displays the first 8 characters. They both have a hd44780 controller, but I notice that the densitron also has an additional OKI row driver. Will the hd44780 drive 16 character without an additional row driver? Or did I some how wind up with some crippled 8 character displays (never heard of it before). I'm guessing it might have something to do with the duty cycle, but I don't want to touch the working source code and have burn new chips. I can't find any references to this problem in any of the numerous online LCD FAQs. Thanks in Advance. PS&FWIW the new displays seem to have a six o'clock viewing angle :-) carl ---------------------------------------------------------------- Henry Carl Ott N2RVQ | talk/chat carlott@204.74.7.186 carlott@interport.net | http://www.interport.net/~carlott/ ---------------------------------------------------------------- "A day job...in an office?
