Hello, dear hackaday!

I've had a lot of problems with my project, actually with my data transfer protocol. It was not the problom with the protocol itself, but something was causing it to not work properly. With help of another hackada member, I managed to solve the problem. It was a data cable problem. The only thing that was also in common with the SRAM module and not with any other module. Hmm, maybe I should give my SRAM another try. So, I would like to thank esot.eric.wazhung for all the help and tips that lead me to solution.

I demonstrate my project in the video bellow.

And always remember:

Tomorrow, I will let you know what are my next goals for my project.

Thank you for your comment! :) You deserved the shout-out ! I really must try that with SRAM yeah. And I will, but I need to get some components.

Hah! Thanks for the shout-out, David!

But, seriously, all I did was throw out a few random ideas.... I threw noise at you. You picked out the right solution from that noise.

Careful twisting those replacement wires! 

Ribbon cable has its place... just ground every-other wire, and you might even get better noise-immunity than your new wiring.

Also, major props on this undertaking. That's a *lot* of wires and chips and peripherals, and a unique new protocol. Nicely-done. Hope it works out with the SRAM!
