hi all members
as u all knows new year starts on this occasion i want to give a gift to this forum
in Proteus 40x4 LCD is modeled as MDLS40466
according to data sheets and manuals of lcd it is just like a 2 lcds of 20x4
and its memory map is as described in link
http://web.alfredstate.edu/weimandn/lcd/lcd_addressing/lcd_addressing_index.html
40x4 lcd has two enable pins as E1 is for ROW1 and ROW2
E2 is for ROW3 and ROW4
40x4 lcd has two controller in it first controller controls the ROW1 and ROW2 and 2nd controller control ROW3 and ROW4
when i make a code and send these strings to lcd in Proteus it not show ROW2 and ROW4 properly as there is a problem in Proteus model
i send these strings
and Proteus result is as
![]()
it is not displaying the ROW2 and ROW4 properly but according to its manual it should be ok
after two days struggle i came to know that Proteus has problem with this model
i really thankful to my friend Fragrance
on www.edaboard.com
he make a Proteus model for this 40x4 lcd i use that model with LCD2X.MDF and MDLS40466.Lib file in fact he make these files but i see once problem there also that is ROW2 and ROW3 uses same location and ROW2 and ROW3 overlaps as shown below but now i able to show it on line 2 properly
![]()
then i open the file LCD2X.MDF with notpad and see this properties
i edit it a little as
and save the file after editing now again run the Proteus
wow
this was the output on lcd
![]()
now it is ready to using with Proteus
now u will think how we can create own libraries in Proteus
for that download Proteus vsm SDK that can be downloaded from here i yet not read it
http://rapidshare.com/files/69946430/Proteus_VSM_SDK.rar
here is a complete code and files used for this lcd
as i also doing it on hardware and will post the result of hardware working soon...
hope so on this occasion u all like this
