QUESTION

Pass multidimensional Array as parameter to function

Asked 2022-Mar-25 at 21:36

I am writing a basic menu system for a TTGO-T to be able to select between different functions, I am trying to pass a multidimensional(2D) array of strings to a function(drawMenu & updateMenu). Ex: drawMenu(TFT_GREEN, 4, options);

The array is defined at compile time. It works if I specify which array inside the function
Example:

The array-to-pointer conversion that occurs when an array is passed to a function only applies to the outermost array dimension. In your case, this means that a char [4][25] decays into a char (*)[25], not a char **, so the parameter types are not compatible.

Change the declaration of the function parameter(s) from char **Arr to char Arr[][25].

Executing C functions from C++ file results in linker error: "conflicting declaration with 'C' linkage" and "previous declaration 'C++' linkage

Asked 2022-Jan-19 at 18:04

I am attempting to execute a C function from within a C++ file in the Arduino framework. The function I am trying to run, GuiLib_ShowScreen, appears in GuiLib.h and GuiLib.c as follows (the files are massive so for convenience and relevance sake I included only definitions):

After trying suggestions from the comments, this cleared out the error. I included the library outside the scope after extern "C" and changed the parameters of GuiLib_ShowScreen() to their native types, defined in the library as #define GuiConst_INT16U unsigned short. There was a compatibility issue placing the include statement within the scope, and because my original error stated previous declaration with 'C++' linkage it seems apparent that the include statement was interpreted automatically as a C++ header instead of C.

Arduino Studio IDE has a flaw regarding compilation: only files in src subfolder of the sketch gets copied to the tmp folder and compiled. So all non-standard libraries should be placed in src subfolder in sketch folder.

Support

The XPT2046 touch screen controller is supported for SPI based displays only. The SPI bus for the touch controller is shared with the TFT and only an additional chip select line is needed. This support will eventually be deprecated when a suitable touch screen library is available. The Button class from Adafruit_GFX is incorporated, with the enhancement that the button labels can be in any font.
