[N8VEM: 19190] Trying to run the Multicomp on an Altera DE2-70 FPGA board

[Kip Koon]

Hi Marcelo!

That is an interesting idea! The only FPGA experience I have thus far is the Altera Cyclone II EP2C5T144 FPGA chip in the original Multicomp design, so I’m not going to be any help with your porting project. I will be following your project though with great interest.

Subject: [N8VEM: 19156] Trying to run the Multicomp on an Altera DE2-70 FPGA board



Hi everyone,



I got myself one of these boards and have tried to port Multicomp to it. It is very different to the one used originally on the project, so I tried to do some obvious needed adaptations (or pin labels, chip type, etc.).

However, all I get, no matter what I try, is a black screen.



I am wondering if anyone here has succeeded running Multicomp with CP/M on this board, or maybe on an Altera DE2(-35) and could share the code. Porting from the DE2 to the DE-70 is (more or less) easy, so I should be able to adapt the code.

I am sure I am doing something wrong, but I still can't figure out what.



Thanks,

Marcelo.

So I went on and got a regular DE2 as well.
Now I have Multicomp running CP/M on both the DE2 and the DE2-70.
All is working fine so far.

Cheers,
Marcelo.
