How to use OLED display for Avnet Virtex4?

Question

I have an Avnet ADS-XLX-V4FX-EVL12-G (Virtex4 evaluation board) with an OLED display. I used Xilinx EDK 10.1 with Xilinx Platform Studio 10.1 and managed to load the base application onto the board (serial connection).

Now, I would like to use a board mounted OLED display, but I have no idea how to get started. I found the uCLinux distribution for FX12 ( http://www.itee.uq.edu.au/~jwilliams/mblaze-uclinux/Downloads/ platforms.html # avnet_lx25), and I tried to describe the steps described in the documentation. When I try to download the .img file to the specified address does not work. I get the following error: MDM Peripheral device not found on hardware. They say that I should use EDK 7.1, but I have 10.1. Maybe this is a problem? (I used xmd.exe from 10.1). There is a support answer on Xilinx ( http://www.xilinx.com/ support / answers / 20060.htm) where I need to recompile the netlist, but I cannot open the project file in 10.1.

In any case, could you point me to a resource, where can I find some basic examples of using OLED? Even pixel highlighting can be a good starting point ...

Answer 1

You will need 2 pieces of information:

• The documentation on the board - which will show you how the display is connected to the FPGA (i.e. contacts)
• If there is a controller chip for OLED, you will need documentation for an interface with this chip. Perhaps, for the logic of the interface, you may need some kind of microcontroller or basic automaton.

Then try the little hellow world design, which does something like blinking your OLED. Then move on to more material.
