LED Amtrix Flackert

Hallo zusammen,

ich habe eine LED Matrix und möchte darauf die Zahlen 0-99 anzeigen lassen. Dazu verwende ich 2 potis (jeweils 0-9). Zur Einstellung der Helligkeit verwende ich ein weiteres poti.

Das ganze funktioniert auch sehr gut!

Nur leider flackert die Matrix dann fürchterlich.
Was mach ich da denn falsch?

Kann mir bitte jemand helfen?

Nur ausgeben, wenn sich wirklich was geändert hat.

Wenn p2 != 9 ist, löscht Du den Stripe. also erst schreibst Du mit p2 == 1 und dann löscht Du und schreibst beim nächsten Umlauf neu und löscht ....

Las das else mal ganz weg.

Wieso mußt Du löschen?
Du überträgst 3 mal Daten an die Matrix.
Zuerst immer etwas Konstantes, dann die Erste Zahl und dann die zweite Zahl. Jedesmal dazwischen löscht Du die Matrix.
Es ist nicht notwendig dazwischen zu löschen.
Die 3 Teile können / müssen gleichzeitig angezeigt werden.
Außerdem mußt Du die Matrix nicht löschen falls P2 nicht 9 ist (else Teil des letzten if). Entferne den else Teil.

Wie hier schon vorgeschlagen wurde, die Matrix nur aktualisieren wenn sich wirklich etwas geändert hat.

Man kann die loop() Schleife aber auch etwas kürzer halten:

Ich weiß nicht ob es 100%ig in "Echt" so klappt, ich habe das nur im Simulator ausprobiert:

Da flackert nix.

danke für deine antwort!

Ich werde es morgen wenn ich wieder zuahuse bin ausprobieren.

Ui der simulator gefällt mir!!! Vielen lieben dank dafür! das ist ja super praktisch!
