Hello,

Can you kindly give more information about the your connection ? Are you interfacing through processor GPIO ? Did you get chance to check with Oscope to make sure you are not getting data into the LCD ?

Can you share the code as well ?

I would like to ask whether you interfaced with FPGA or HPS IO ? I assumed it is HPS .Kindly confrim

 

Thank you,

I'm working on (http://www.terasic.com.tw/cgi-bin/page/archive.pl?Language=English&No=593) this board. Same code is working with DE2i-150 Development board. What are possible reasons to not obtaining the characters? Below is output image.

sorry for very late response, Didnt terasic dont have the example RTL for the same ? it also depends on the RTL and also I see hw you wired it and connected via breadboard.

Too many variable to assume without further data on myside :(.

 

Thank you ,
