Yes, a graphing calculator for a credit-card-sized device. Fully functioning graphing, tables, and function editing! (unfortunately with presets)
I just to see if I could squeeze my graphing program into less than 32KB. At first, it seemed impossible, but then I found out I could just combine some unused arrays and I got 10% of my memory back.
How to install
Download the .arduboy and use a program like Arduboy Manager!
If you want to change the source code, just download the .ino file and open it in the Arduino IDE.
- Up and Down: move cursor
- Left and Right: decrease/increase selected variable
- A: Go back to the graph screen
B depends on the current screen.
- B while on graph and function screens: confirm
- B while on function variable, window, and table screens: switch between adding 1 and adding 0.1
- B while on the "Oh no!" screen: escape
