Hi everybody,

I hope i do it right....

I would like to know how I could mix byte content and text content on a led matrix...

I could do one separately but i don' see how i could mix both..

Thanks for your help...

What particular LED matrix?

I use the 8x8 matrices that can be daisy chained.

Using the Parola library I can easily mix text animations and graphics (sprites).
You will save everyone's time if you read and follow the forum guidelines.  :)

Except that article does not appear to comprehend how to configure the particular matrices in the MaxMatrix or Parola library., so it is a bad example!  :smiley-eek:

If your logo is simple then the Parola library can do a sprite, as mentioned above. Here is a blog post and video of the library using sprites: https://arduinoplusplus.wordpress.com/2018/04/19/parola-a-to-z-sprite-text-effects/. The code for the display shown is the library examples.

If you want the logo to scroll like the message (ie, with the message) then you need to define the bitmap as a character that you can insert in the scrolling string. This is also possible with Parola.

That does seem to be what was requested.

Good fun defining additional characters.  :smiley-lol:

Defining and adding characters on the fly is straightforward, and they can replace existing characters. Please refer to the addChar() method in the library documentation.
