It has trig functions, basic graphing capability, square and other roots, positive and negative numbers, decimals, e, pi, and parentheses. It is a fully functional scientific calculator with graphing capability.
I plan on adding in table functionality in the future as well, but I want to get it working first.
I started the basic calculator and set up what it will look like.
Put the screen on the Arduino
Upload the code and run
I love the choice of platform. When put together, the Arduino + Seeed Touch screen LCD are very versatile. I have personally created a cellphone (with a GPRS Shield), an Enigma Machine Simulator, and a port of one pixel Pac-Man with this platform.
Great start! I can't wait to see where you go with this. How do you plan to do trig on it?
If you're asking where they are, then it's the sn, cn, and tn buttons. If you're asking how would I actually do the trig, then I figured there was a library for it somewhere online.

Are you still working on this, and do you happen to have the code? I can't find it anywhere on this site
