Hey guys. I'm still working on my display for my racing sim.
I plan to build a shield for the MEGA which will have my 5 shift registers and supporting components, and 8 resistors for the 7-segment displays. Possibly a smaller shield as a breakout board on top of that one to make all the connections to external wires.
The obvious solution is to move some of the shift registers to the display itself, which will reduce wiring. But, for now i'd like to keep the displays fully modular. I may move the registers in the final design.
My main problem will be connecting this shield to the main display unit, that will sit on top of the wheel. Right now i've got 27 connections that need to be made, and I may possibly be adding a couple more to the design.
What's the best way to wire this up? I was thinking either a ribbon cable, or perhaps something similar to a CAT5 cable, but with more connections. Then a giant array of male headers on each board to connect the cable.
