SPI vs I2S Led Matrix driving with ESP32

[@rajeshkolhe1522]

Hi sir , i have P4 RGB 80x40 10 mod scan matrix.. i had tried to many programs and made self running function using for loop.. i am just focusing on 7 color using RGB 000 to 111 i am using buffer[160][20][1] , also mapped zigzag rows. But my data transfer is slow because of using for loop to set data RGB . I want to add more displays can you please guide me about it?

[@yerkstranger1049]

is it possible to drive 10 or more RGB Led panels?

[@atc1441]

That is unfortunately to much RAM, better use an Raspberry pi for that many

[@Davedarko]

How is I2S faaa ahhhh, was thinking of I2C first. Nice!

[@UnexpectedMaker]

Great showcase of the performance you achieved!

[@foadyousefi]

Cool comparison. Can you please share link to libraries you used or maybe create a full detailed video?

[@atc1441]

Added it to the description. There will be a video about it in the future

I have a question, I would like to have a 256 x 32 matrix and display the BTC rate is it possible? it can also be 64 x 32 can you write this code on a btc tricker? What cost code its?

[@futuretechnovation4415]

Can we connect to nodemcu and use that library for p3 64x64 indoor pannel

You did a video on the capability, Which is not available on any channel, Hat's off to your hardwork 👍👍

[@atc1441]

Thanks as well!

[@bramSDASCL1759]

Nice,, 👍 My question is, how do you calculate fps and color depth??

[@atc1441]

I set the depth in the library, the fps is then the fastest possible way to change something in the image, the actually pushinh of the image to the display is happening even faster on the i2s version

[@bramSDASCL1759]

@@atc1441 ok, so there is an option in the library to set depth. Thank you

[@atc1441]

Correct :)

it's 3bit max = 8 colors. show us all that 24bit colors please

[@atc1441]

Here is an example where you can see the 24bit twitter.com/atc1441/status/1176570943994519553?s=19
