I'm currently working with the Waveshare 5.65" 7-color screen (GxEPD2_565c) - and I'm attempting to write a bitmap to it row-by-row using the writeImage method from GxEPD2. However, the screen will always remain blank. I have verified that the screen and setup do work with other methods by using other examples from the GxEPD2 repo.
I've also verified the code with a BW screen and writeImage works fine on that.
I wondered if there is a known limitation with updating this kind of screen this way?
