Have you already made it with the atmega328P (Or w/e it was)?

Okay here is what's happening: I'm breaking up the TI-nterface project into smaller projects. Since one interface for everything was not effecient I decided to make a whole bunch of peripherals for the calculator. I recently built two peripherals which can be found in the hardware section.

Yeah it was discussed in another thread and kinda looks interesting, although it would kinda suck if their inspiration was taken directly from your project

On cemetech they told me it was a prototype and not the finished product. The finished product would be a stand alone calculator. Probably without a screen. I wonder if they will still use the linkport to connect to the calculator, but internally. We'll see. Maybe the guys from cemetech could ask the developers if they saw this project. At the very least: I was first.

Yes. In fact this is the soundchip project which will eventually have some I/O as well. It is remarkably easy to make the interface when I got the soundchip all sorted. I will release multiple versions of the Nterface project. One being a barebone link protocol libary for the arduino and another one will only have the I/O. The first version to be released will be the soundchip TIMID.
