In what language is the code written for the car?

Question

Programming

What language is used to write code for machines, control panels, and how can you take out the panel and load the code there in order to visually change something there?

Answer 1

For everything, although usually C
Now often the control panel has its own personal brains with its own closed OS that still needs to be hacked. You can't just take it and change it. In the best case, you will get a hex dump of the firmware.

Answer 2

Since manufacturers protect their devices from extracting the code, this will be very problematic. Maybe there is support for graphic themes or skins? Ask the manufacturer.

Answer 3

On different.
In Python, in Java, in C, in C++ - I know for sure.
Maybe on something else.
The second part of the question - how to change - is too general a question.
In each specific model - it's all very individual.

Answer 4

I recommend rewriting everything either to joins or to enumerations of tables separated by commas. And don't use both at the same time. It is quite possible that in the process of rewriting the error will disappear))
