user62520: Thanks for your presentation https://arduino.stackexchange.com/tags/max7219/info.
You say that multiple MAX7219 8x8 blocs can easily be daisy-chained and you show an example of at least 12 blocs displaying "Testing12345".
Trying several programs I found for Arduino, I never succeeded to chain more than 8 blocs with 8x8 matrix (either 8 individual blocs or 2 groups of 4 as on your image).
So I'ld be very happy if you send me examples of programs managing more than 8 blocs for fixed or scrolling displays.
Many thanks in advance.

user62520: All is OK changing the proposed statement
define HARDWARE_TYPE MD_MAX72XX::PAROLA_HW
to
define HARDWARE_TYPE MD_MAX72XX::FC16_HW
