* Broke up the code into more general functions instead of duplicating code
* Made stuff const and removed variables no longer used
* Use defines for menu button values
* Changed the order or things to avoid forward declarations
* Use array lookup instead of switch-case on some menu options
* Adjust menu functionification
* Cleaned up sensor rendering
This bug would probably never happen in real life, and could be fix by holding down menu and enter buttons at startup. But a bug is a bug.
The only reason I found this bug is that the simulator didn’t initialise EEPROM to 0xff, and even after I did that it crashed, because a version of 0xffff wasn't handled.
A bug in the current NuEVI.ino does not write all default values to EEPROM on the first boot, unless menu + enter buttons are pressed. I added a workaround to the simulator that fakes that the buttons are pressed when calling the setup function.
* Press W in simulator to activate (pretty slow shit, do avoid unless compiling with optimisations)
* Tiny improvement of the EEPROM simulation.
* Fixed type typo for millis and micros
Builds a native program on MacOS that runs the NuEVI firmware compiled for x86_64.
Only input is arrow keys for menu buttons for now. Only output is console and display.
Copied some more library files into the simulation folder, and renamed the modified *.cpp files from the libraries to *_sim.cpp.
No need to convert a value to double when all we want is a two digits converted to string.
This also avoids linking some math library, which saved almost 8K och program storage space.
This change required lots of other changes to have it compile. I had to declare all variables from NuEVI.ino used by the menu as extern in a separate header file (globals.h).
Also I moved all defines from NuEVI.ino to a config.h file. I think some of these could be moved back or even moved into menu.cpp.
I declared many variables and functions in menu.cpp as static and moved them around to avoid forward declarations. For simplicity I did some forward declarations anyway.
Some varibles only used in menu.cpp was moved from NuEVI.ino instead of having them as externals.
