Thanks ,
i´m planing to remove the 7 seg and add one joystick and some pushbuttons (like gamepad) and leds...
The 7 seg fills a lot of space and it´s not so usefull...
...........
I have enought idle pins the other header is fully empty
What is your opinion?

No problem send you my email, I prefer remain here so other can contribute to development and or wish list.
My idea can be to make some piggy back so one can add what it like, one board for memory has length and time constraint too so just the memory on board then plug other interfaces to top that can bbe everything.
Ex LCD TFT + Key + Joy
16x2 LCD + key + joy
ADC DAC
Motor Interface..
Just what you think can be added on a stack as it is on Beagle Board (Black-)

Your idea is to transmit hdmi from fpga to ad 9980 and then feed the 7123 wit the 9980´s output?
The main concern it´s that both chips are expensive ...
And what about use only the 7123 and people who has not vga monitor use an vga to hdmi adapter?
Or dont use any ad chip and feed the hdmi directly from fpga and place and vga conector too but with 5 bits r-ladder dac
If we have fpga why use an 9980 like chip, we can make it in hdl ...
Send me your mail for discuss the layout if you like...

My idea was to leave board with HDMI using few pin pairs, impedance is not correct but can be close and a very short stub refelect also a small amount of energy.
On the other side of HDMI you can build an universal HDMI 2 VGA and it can be used for every monitor. You can provide also an LCD TFT standard 40 pin connector to use for parallel TFT.
We can develop just using a small MAX V.
See you, my time slot now is terminated see you soon.
