Slow rendering with 128x96 pixels #25

Great animations.

Have you tried running with a large panel before? It looks great (some only render a small circle in the middle of the screen). The problem is I average about 5fps :/. I'm using Teensy 4.1. I'm guessing this is to be expected when trying to drive 12,288 pixels.

Hello I am running them an a 128x96 using and esp32. but I am using a Special driver that allows me to refresh the panel à 128fps. so I can have better fps. which animation are you using ? I could make a benchmark (even if the teensy is way more powerful than the esp32 at flaot calculation)

We both have the same panel size and it sounds like you are able to have a much higher fps with a less powerful chip. I wonder what I am doing wrong. For example, the Hot_Blob() animation gives me 7 fps. It does 4 calls to render_value() and I think the slowness happens in here. Printing the statistics: 7 fps 86 kpps @12288 LEDs 137322.00 µs per frame Rendering: 99.00% Sending data: 1.00% (135301.00 + 2021.00 µs) 135ms for rendering 1 frame. That's a very long time, which equates to about 7fps.

Hello With how many pins are you driving the panel ?

ssaenger commented 1 month ago

I'm driving some HUB75 panels. I don't know how many pins are being used, but that is not the issue. I can drive these panels over 200fps for example. From the little statistics printed in my earlier message, the delay sending the data only accounts for about 1% of the total delay.

hpwit, how long does it take to render a frame on your end? Do you have any video showing these animations being played? Thanks.
