Nobody make this kind of basic RPN calculator on the market.

One of my aims is to create a calculator that the user can customise easily. It only took a few minutes to convert it to a 4 level stack and add a percent function.

After you've created your keypad layout, allocate the key numbers to the functions in the header file.

e.g. my ENTER key is in the bottom right corner (key 0) so in the header file I have #define ENTER 0. If you don't want a particular function set it to -1.

You can add a shift plane, a key held plane, make it programmable, change the font size, colours, status line, menu, etc. etc.
