Im not sure quite how to phrase this question so please bare with me.
I have an Arduino ADK board (which I understand to be very similar to a Mega 2560) and a 4Display Systems 4Display-shield-160 which sits nicely on the ADK and works fine.
My problem is I have a few extra bits and pieces such as a 9DOF stick and a GPS unit (406a) that I want to connect too, and some the pins I want to use are "covered" by the 4Display-shield-160 but not actually used.
Accordingly I went out and bought a Mega Proto Kit (http://proto-pic.co.uk/arduino-shield-mega-proto-kit/). Now this doesn't have pass through pins, but each of the pins that comes through from the board below has a "sister hole" that I can connect to to use that signal/function, but obviously I can't stack the display shield on top of it.
I then went out and bought a Mega Shield Kit (http://proto-pic.co.uk/megashield-kit-for-arduino-mega/) which has the pass through for the pins so it will work fine with the display shield, but it doesn't have the parallel "sister holes" allowing me to connect the other signal/functions required.
What is the usual way for dealing with this kind of problem?
I hope I have explained it in a way which can be understood.
Thanks for your time.
