Having trouble with 3-wire Serial LCD Module (Arduino Compatible)
russel_wood@hotmail.com 2013-02-26 14:16:57 5418 Views6 Replies Cant seem to get this up and running. I am having trouble understanding the explanation of the pinouts because the labeling is different from the wiki. If I followed the order the top right pin is 1, and below that is VDD, then is top middle pin RS(CS)? Is the middle bottom pin RW(SID)? Is the top left pin EN(CLK) cause it looks like it's labeled SID?
Even the demo code that comes with on the wiki wont compile. And that's before I even hook up screen.
Help please

2014-09-10 08:14:13 User Moment said he user u8glib with lcd12864 module and it worked. I am having problems and and evidently not allowed to personal contact. I would really like to find how he set this up, I find the data somewhat confusing, but I am a newbie.

alfiesty 2013-03-04 12:43:13 Well actually I never could get the example from DFRobot to work. I used the U8glib and I was off to the races.
The pins are all set in the library but when I compile I get this error...

russel_wood@hotmail.com 2013-02-27 17:31:22 Ok, good to hear. But would you mind to share what went wrong? My first guess was that you had some wrong in the code or/and the library was not installed. lumi
lumi 2013-02-27 12:07:24 Problem solved. I fixed it with stick-to-it-tiveness!!!!
Thanks russel_wood@hotmail.com
