Version2 of Scientific RPN Calculator (with ATTINY85)

[deetee]

Hello all!

Only some weeks later I am proud to present the version 2 of ScArY - my "Scientific RPN Calculator" based on an ATTINY85 microcontroller.

With help of members of this Forum (especially Pauli) approximately 1kb of codesize could be saved - which is pretty much. And many ideas where provided what to do with this extra space. Thanks for this.

So ScArY became a simple and cheap scientific DIY-calculator with RPN functionality and many functions. Very impressive is the possibility to save physical constants and sequences of keypresses ("almost programable") permanently to the EEPROM.

Hi Pauli!

Thank you very very much for your help, time, experience, private lessons and ideas.
I could not come so far without it - and ScArY is one of the best things I have ever developed.

Right now I am dreaming of a similar thing based on an arduino pro micro with much more features (programable, usb-pc-link). Let's see ...

That's a great little calculator, good job!
