I want to hack a canon calculator, either the ms81 or the ex911, the point is that the caluclator would be able to solve more complex things like functions with two variables and would be able to find them, and would be able to show steps for it, and bringing in a more advanced calculator wont be the solution for me, i need like a cheat calculator, that is one of the models i specified above, and would be able to do all the things i said while still looking like a normal science calculator, i already got a very small esp32 chip, question is mainly how do i take control over the calculator like the screen and buttons.
If you look up a cheap solution, buying a ready-made science calculator will be a best choice.
Design it yourself will be a very long journey.
Firstly, please explain your experience in programming and electronics.
In my opinion, screens and buttons (keypad or keyboard) are not the main problems.
For me, the main problem is knowing which algorithm should be executed for each mathematical/financial/scientific function.
Do you have the equations for these functions that you want the ESP to execute?
Do you have a list of the functions that these calculators mentioned, (ms81 or the ex911), execute?
