Received my 13Spectra two days ago, and tried some of my code until I find out I am unable to display green color. So I tried the example with big color stripes, called Inkplate13SPECTRA_Full_Screen_Colors and it does not work either. The colors are (from left) Black, White, Yellow, Red, White and Blue.
What I am doing wrong?
versions:
Soldered inkplate boards 3.0.0
InkplateLibrary 11.1.4
code of example:
/**

When tried InkplateLibrary v11.1.3, green displays correctly, so the problem is possibly in the last version.
