drawing arcs instead of rectangle to display midi value

[benwadub]

hi, your code is really inspiring for my midi controller project, I d like to draw the midi values with round shape instead of rectangle, have you an idea how I could do this please?

It doesn’t look like the ILI9341 library I’m using (https://github.com/PaulStoffregen/ILI9341_t3/blob/master/ILI9341_t3.h) has arc drawing functionality, however the Arduino GFX library does (https://github.com/moononournation/Arduino_GFX/blob/master/src/Arduino_GFX.h). So either swap the library for this one, or you may be able to just copy and modify the arc drawing functions to work with the existing library. Though I have not tried this nor used the arduino GFX library.
