Thx for your reply.
Below there is the code I used; as I mentioned this is just the Parola_Zone_Display example, modified to 32 modules and 4 zones.
Parola version is 2.7.4, MX_MAX72xx version is 2.10.0., IDE version is 1.8.5.
#include <MD_Parola.h>
#include <MD_MAX72xx.h>
#include <SPI.h>
// Define the number of devices we have in the chain and the hardware interface
// NOTE: These pin numbers will probably not work with your hardware and may
// need to be adapted
#define MAX_DEVICES 32
#define MAX_ZONES 4
#define CLK_PIN 13
#define DATA_PIN 11
#define CS_PIN 10
// set to 1 if we are implementing the user interface pot
#define USE_UI_CONTROL 0
#if USE_UI_CONTROL
#define SPEED_IN A5
#endif // USE_UI_CONTROL
// Hardware SPI connection
MD_Parola P = MD_Parola(CS_PIN, MAX_DEVICES);
// Arbitrary output pins
// MD_Parola P = MD_Parola(DATA_PIN, CLK_PIN, CS_PIN, MAX_DEVICES);
#define SPEED_TIME 25
#define PAUSE_TIME 1000
// Turn on debug statements to the serial output
#define DEBUG 0
#if DEBUG
#define PRINT(s, x) { Serial.print(F(s)); Serial.print(x); }
