Modifier un code d'un panneau LED d'affichage défilant

Bonjour,

Voilà je viens vers vous afin que vous puissiez m’aidez à modifier le code Arduino ci-dessous que j’ai sous la main. En effet c’est un code fait spécialement pour piloter un panneau LED d'affichage défilant d’une dimension de 6x24

(Voir schéma ci-dessous)

https://drive.google.com/file/d/1Ctr...ew?usp=sharing

Donc ma question ou ma demande est toute bête et qui s’agit bien de comment ou bien quelles sont les lignes à modifier afin que ce code me permet de piloter un panneau d’une dimension de 8x48

(Voir schéma ci-dessous)

Merci beaucoup par avance ;)

Voici le code du 6x24 :
