Hi, I'm trying to display a grayscale bitmap using drawXBitmap, and I have also tried drawGrayscaleBitmap, but nothing is working. I have a 3.7-inch Waveshare screen.
@ZinggJM , I would like to know if you have any tips or solutions for modifying existing functions to display grayscale bitmaps using those libraries and a 3.7-inch Waveshare screen.
ZinggJM may not be available.
