Beginners • Re: Recommended graphic display for signal animation

You can use a 4 inch SPI LCD with the Raspberry Pi zero 2w
(the example below is for the raspberry pi 3b)

I would like to know what you use for graphing. I used tkinter and matplotlib in another SBC.

But Raspberry already progressed into Wayland... and I read somewhere that tkinter wouldn't work.

Hi,

Thanks, I think I will use the same display as you - 3.5" ILI9486 display.

I plan to plot points / draw a graph using python PIL ImageDraw methods, then I display the graph using a display library (e.g. https://github.com/ustropo/Python_ILI9486). I will repeat this for each frame. Each image frame is displayed for 0.1 s and then changes to next frame to give animation effect.

I tried this with a 2 inch waveshare module and it successfully worked (https://www.waveshare.com/wiki/2inch_LCD_Module).

Do you know if this graphing method will work for 3.5" ILI9486 screen? And do you recommend any libraries?

Thanks
