Evolution replace NFC Frequency display (which requires OpenGL/shaders) with 2D graph (without OpenGL requirements)

bvernoux commented 3 years ago

A potential evolution could be to replace the NFC Frequency to use only simple 2D Graph to work on old computer with integrated graphics card (which does not have OpenGL+Geometry shaders) as it seems a bit "overkill" to use OpenGL with Geometry shaders to display the NFC Frequency.

For example it is not supported with Intel Graphics HD 4000 and I need to use GeForce GT 650M to display correctly the NFC Frequency which seems a bit overkill for that feature.
That will avoid dependencies on OpenGL + Geometry shaders too
That will probably help to build this amazing application on Android Phone as I really doubt they support OpenGL + Geometry Shaders (except maybe the flagship phone)

Yes,

The opengl chart is a nice feature but it doesn't provide much information, I added it just to practice with Opengl Shaders.

In the next version I will include a check of the Opengl capabilities to toggle the use of geometry Shaders and ultimately disable this feature completely.

Thanks for de suggestion
