nice, I should try that, I guess I start with wiring the vga...
Excellent work, a lot of work to wire the daughter board, but really interesting
Nice work Caro!
Btw for anyone interested in copying this: I'd first have a look around to see if there's other projects out there that tack a VGA output onto a DE0-Nano. And check Altera's (excellent!) documentation + design examples too.
Why? If there's an existing 'default' VGA example or some other project that's both interesting / related / popular and uses a VGA output, you could use the same hardware to run those projects and this 1chipMSX port.
Changing a few I/O pins in an FPGA design that already works, is trivial if the hardware is an add-on board. But plugging / unplugging different external boards + cables to run different projects (when both use the same monitor to output stuff), is well... annoying.
I have not found the daughter board for DE0-Nano, suitable for the realization of OCM.
Therefore did his own version.
If you have any other suggestions, let's discuss.
the only add on board design I"ve seen was for a PC-Engine, I'll need to find the url.
Goooood~~~
Nice Work.. Caro.
well..
Can I ask about NTSC out
My NanoMSX was displayed black-white (no color)

I dont know why.
How Can I fix it?

Using a clock signal generator on the basis of the phase accumulator
possible to obtain a frequency of 21.47727 MHz.
The result is now correctly generated signal NTSC, that allowed us to obtain a color image to TV.
New version.
Very nice job,
I think that within next week I will be able to adapt the source for my shield board for de0-nano.
I will post the modified vhdl source very soon.
If somebody it is interested for the PCB of shield or the mounted board can ask me, I have done 20 PCB.

Hi all,
Just finish the porting for my de0 nano shield.
Have a look at http://youtu.be/hCQDGWA_APU
Many thank to Caro for the excellent job.
Regards
