Layzer 0 Posted May 22, 2017 (edited) Hi, I ran this code: https://reference.digilentinc.com/fmc_hmi/fmc_hmi to see the demo for the FMC-HMI screen which I need to integrate in my project, the problem is that I cant display vertical lines. I tried to add this line too: blue_reg <= x"FF" when VCnt > V_800_480p_AV/2 and VCnt < V_800_480p_AV/2+2 else x"00"; but the vertical line doesnt show I would be glad if someone can rescue me! thx in advance Edited May 22, 2017 by Layzer Share this post Link to post Share on other sites
0 RisinT96 0 Posted May 22, 2017 (edited) Hi, You mean the test pattern file located here: https://reference.digilentinc.com/_media/fmc_hmi/fmc-hmi_stripes.zip ? Additionally, where exactly did you add your line of code? More information would also be welcome, what does the display show? Is it empty/full? Tal Risin.

0 Layzer 0 Posted May 22, 2017 (edited) EDIT: My solution doesn't work, it worked for the wrong reasons. Hey, I solved the problem. The solution is to connect vertical sync signal in the constraints file to pin D22 instead of pin D21. (This solution is valid specifically for the Zedboard Rev C) Maybe you should update the file I linked to. Thanks anyway, Layzer Edited June 12, 2017 by Layzer Share this post Link to post Share on other sites

0 D@n 410 Posted June 12, 2017 @Layzer, I'm not sure the title of this post is helping you out. With a title that starts with [SOLVED], you may not be getting the attention this issue needs. Dan Share this post Link to post Share on other sites
0 JColvin 340 Posted June 12, 2017 The title has been edited as appropriate. Unfortunately, I'm not familiar enough with the FMC to give any useful feedback though. And quoting @RisinT96, where did you add the line of code that you were originally attempting to add (even though it apparently didn't solve what you were seeing)? Also what does the display show when you run the project? Thanks, JColvin Share this post Link to post Share on other sites
Hi,
I ran this code: https://reference.digilentinc.com/fmc_hmi/fmc_hmi
to see the demo for the FMC-HMI screen which I need to integrate in my project, the problem is that I cant display vertical lines.
I tried to add this line too: blue_reg <= x"FF" when VCnt > V_800_480p_AV/2 and VCnt < V_800_480p_AV/2+2 else x"00"; but the vertical line doesnt show
I would be glad if someone can rescue me!
thx in advance
