I just bought a 128x64 OLED FeatherWing. There appears to be multiple dead lines across the display. Circuitpython code produces an all white background on other identical parts. Since its driven by i2c and otherwise working it looks like I have a faulty part. Please advise.
Code: Select all
color_bitmap = displayio.Bitmap(WIDTH, HEIGHT, 1)
color_palette = displayio.Palette(1)
color_palette[0] = 0xFFFFFF # White
bg_sprite = displayio.TileGrid(color_bitmap, pixel_shader=color_palette, x=0, y=0)
main_group.append(bg_sprite)
