Hi all,

For a project here at work i need to read a 48bit parallel bus into the PCI of a computer. The Bus exists of 16 control bits and 32 data bits... My problem is that i don't have enough IO pins on the Dragon board if i use PCI .... Guess i did not do my homework properly . Now is my question, can i add a daughter board to the dragon using the FlashyD connector to have more IO pins , for example the Pluto board has the same FlashyD connector.... Is this compatible? OR is it better to add a second dragon board in the computer.... I need to be able to communicate with the bus in both directions. Just for the guys who are are thinking what sort of bus this is..... it is a Selbus from a old Gould computer (very old stuff).
Anyone an idea how to do this the best way?
Personally i don't think its possible to use 2 dragon boards anyway

Greetzzzzz,

Hi Beemer,

Did you sample the bus? If yes, what is the sampling frequency?
Otherwise, what is the bus frequency?

Depending on your answer, I think I can give you an appropriate advice.
