xps_tft problem: VGA displays repeated rows (Nexys2)

[barbaromaykel]

Hi,

I trying to show a string in VGA using TFT module present in XPS.. I use a Nexys2 board. I have not enough internal memory for the xps_tft video memory (2 MB needed) so I have to use the external Micron RAM. I have managed to show the characters on the computer screen, but the row number of the characters is higher than expected. That is, each row is repeated four times.

Can anyone help me solve this problem?

Best regards,

Bárbaro

Look on on line 237 of the file and insert the following lines in your code:

---

Code Verilog - [expand]
1
2
3
4
5
if (no_code_no_testbench) begin
  no_help <= 1'b1;
end else if (posted_code_posted_testbench_good_problem_explanation) begin
  helpful_answers <= 1'b1;
end

---

. :thinker:

The alternative is to post all your code and the testbench and perhaps get a more useful answer!
