Nigel Goodwin Super Moderator Most Helpful Member May 28, 2009 #2 Can't help you in C, but my tutorials show you how to do it in assembler, complete with circuits.
E eva New Member May 28, 2009 #4 i havent receive the lcd yet. the project given haven specify yet. can u give me example how to write it ? i m using CSS c compiler.

AtomSoft Well-Known Member May 28, 2009 #5 i dont use that compiler. I use C18 but most C compilers are similar and require little changes if the code is well. You need to know what type of LCD it is. The Pins it has and the controller it uses to write code for it and to wire it. Otherwise its like being blind and someone asking you is the light red?

Click to expand... Or even better, stick with the 877 and use an LCD text module, rather than just the glass LCD.

Nigel Goodwin Super Moderator Most Helpful Member May 29, 2009 #13 Google for HD44780, it's EVERYWHERE - most (all?) of the details you need are listed in my tutorial.
E eva New Member May 29, 2009 #14 well, i google already. what i download is not the datasheet of HD44780A00 but HD44780UA00

Google for the number I posted above, it wasn't a random choice. And again, check my tutorials, paying particular attention to the mention of the EPE LCD articles.
