Hi

I've using the unilumin 128x64 rgb led display of size 320mmx160mm which is P2.5 and mentioned as 32 scan in the datasheet. I tried the library and i'm facing the flickering issue in python code. Please help me to resolve the issue. i tried multiple settings value and still can't be able to fix the issue. Anyone please help.

my code: graphics.DrawText(offscreen_canvas, font4, 0, 24, textColor_green, datetime.now().strftime('%I:%M:%S')) graphics.DrawText(offscreen_canvas, font2, 0, 42, textColor_blue, datetime.now().strftime('%A')) offscreen_canvas = matrix.SwapOnVSync(offscreen_canvas) time.sleep(0.5) offscreen_canvas.Clear()

Hi @combs ,

I've tried the performance options and it seems i can get the flicker free only if i reduce the pwm bits to 2.. but it reduces the color quality. Is there any better way to improve? Please help.

use c binding instead of python, you will be amazed with the performance
