Honored ContributorWriting Data In SDRAM
Hello everyone,
I've used some VHDL before but I need help understanding how to write data into SDRAM. I'm currently using Quartus II 11.0 and DE0-Nano. I just need a sample VHDL with some comments in it and I'll try to figure the rest of the stuff. Any help would be appreciated. Thanks.6 Replies
Altera_ForumAre you sure VHDL is the right solution then? If you have an embedded CPU it may be easier to so it by software, as you have such a low frequency.
What kind of interface do you have to your sensors?- Altera_Forum
I have to hook some meteorological sensors (digital) to the DE0-Nano and store the data in SDRAM. The board is to read the data every 5 seconds. It will run for approximately 10 mins.

I suggest to have a look at the Avalon specifications and especially the memory mapped master interface. You can write a component in VHDL that uses this interface to access memory, and add it to your SOPC/QSys project.

What is the source of the data and how fast do you need to write the data into the memory?

Yes, but I also have access to Qsys. Also, I'm not only limited to the DE0-nano board but also have DE0, DE1, and DE2. If you can help me with any of those boards I would really appreciate it.

Are you using SOPC builder?
