128x64 OLED FeatherWing, multiple dead lines across display

Post by devnull_0x0 »

Hi,
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)

Thank you for the advice.
Unfortunately it is still there after running the example code from the guide.

Thanks for the additional check. Yep, looks like something's up. Let's just replace it.

Send an email to [email protected] with a link to this thread and your order number and they can send you a replacement OLED FeatherWing.
