LCD SCREENS

[Justme]

Good day all,

I really enjoy taking stuff apart and then putting it back together.

I've been reading about the components of low level devices which have LCD screens.
I've been researching what makes the numbers on the screen.

I'm especially interested in accessing the coding database on microcontrollers (?) so I can see my microwave go something like 10-9-8-3-6-2-4-1-2-9 Beep! Or pressing 5 on a calculator and seeing 7 appear!

Must I need to know C? Is the output of LCD screens accessible/encrypted on basic electronics such as calculators?

Or pressing 5 on a calculator and seeing 7 appear!

That's easy..We used to do it all the time in the office.
Just swap the buttons or pads.
Really confuses people.
It was a prank and has nothing to do with your question.!!!

If you want to change the displayed data for a particular key, just change the matrix pattern/sequence..
