Please upgrade to a Xilinx. You can also download the project files here on GitHub. If I write a good post, then I have been good for nothing. You are not charged extra fees for comments in your code. They are shown with pin description, pin name from the LCD datasheet, and the net name from the ML schematic.

Jeff on July 18, at 8: Peter on May 31, at 2: Jeff on September 1, at 9: Yes, you can simulate in modelsim.

The LCD interface consists of the 7 signals listed below. Yohila on July 25, at Without a board, it will be hard to verify your designs, but you can still learn by simulating your work. BTW, the two pages I found in the forums that were useful are: I tried to open the original project you have put on your site to see if I could figure the differences between two or not, now the issue is that since I musing XPS The specified object is spelled correctly in the constraint source file.


Copying code is not the same as learning to design. They are shown with pin description, pin name from the LCD datasheet, and the net name from the ML schematic.

Provide useful details with webpage, datasheet links, please. Read the manual or user guide.

I have no board to support EDK. Jeff on Lm505 25, at 7: The main function of the mml505 application will provide a simple example of how to clear the display, write a message on the LCD and to change the cursor location. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. A delay function will be used to create the required signal timing for the LCD interface.

We have detected your current browser version is not the latest one. To achieve the required signal timing, the application contains a delay function that uses the Timer peripheral.

Can you please advice me how to resolve this issue? It is recommended that you read those documents before following this design.

Wei on September 26, ml5055 4: Of course you shouldn’t have to write your own controller code! I tried this tutorial with the ML board. Miles on August 24, at 3: Or if a Xilinx employee can supply me with one.


We now add a m,505 peripheral to the project to allow the Microblaze to measure time delays. But in case you are compelled to do so, feel free to post your code for everyone to share. Please upgrade to a Xilinx.

It contains several functions for performing the signal sequences for writing characters to the LCD, moving the cursor, etc. And if you want to stray off the Xilinx website, there’s this. Do not post a new topic or question on someone else’s thread, start a new thread! I am not paid for forum posts.
