Honored ContributorHi guys.
I am having problem with my project. I have used lpm_rom for my design. My lpm_rom contents data of my image. And now I dont know how to read the data on ROM. Kindly help me. Thanks
Honored ContributorTry check on Quartus II help, Quartus II Help v15.0 > lpm_rom Megafunction, to see if it is helpful?
Honored ContributorWhat exactly are you having a problem with? a rom is just a memory - you provide an address and you get a value out.
Honored ContributorDear Tricky.
I want to display contents in my lpm rom to VGA monitor. I have read some information on internet. They said I need to " to read the ROM include two counters, index_column and index_row". And now I dont know how to make two counters, index_column and index_row". Thanks for your help.Honored ContributorCounters are in just about every basic VHDL tutorial.
And to display it on a monitor, you'll need a controller for all the VGA timings (again, lots of counters)Honored ContributorDo you mean VGA controller? I already have tried to display very basic tutorial display blue color on VGA monitor. I already successfully did it. But now, I'm confuse about display content in lpm rom on VGA monitor. I already did the .mif file for my image. Which part should I edit for my design? Do you have any tutorial similar with my problem?
Honored ContributorI don't know if a tutorial. It you already wrote a vga controller, then all you need to do is present the days from the rom at the correct time. So just use a row and column counter as the address.
Honored ContributorSorry Tricky.
What do you means by " present the days from the rom at the correct time"?Honored ContributorSorry, present the data from the rom at the correct time
Honored ContributorI dont really know what you want. You synchrose your code with the VGA controller, so that you always know what pixel is being played out on the screen. then you can fetch the correct pixel from the rom.
