Problem mit u8g2 bleibt dunkel

Hallo,
ich habe mir einen Sketch geschrieben und am Anfang ging auch das Display.
Nur habe ich irgend etwas geöscht oder falsch geändert dass nu8n mein Display immer dunkel bleibt.

Das paßt nicht zusammen, Du mußt Dich für full_buffer oder page_buffer entscheiden.

HotSystems · September 22, 2023, 7:05pm

Mein Tipp, nimm den letzten Sketch aus der Sicherung.
Da kannst sicher den letzten Stand wieder herstellen, oder der funktioniert sofort wieder.

Und was verstehst du unter Standbild ?
Möchtest du Videos anzeigen ?

Und zwischen den Beiden gibt es keine Sicherung ?

stich73r · September 22, 2023, 7:19pm

Nein das Display blättert die Page nicht weiter.
Es steht dann einfach die letzte Ausgabe im Display und nichts passiert mahr.

HotSystems · September 22, 2023, 7:28pm

Im letzten Sketch machst du den Fehler, dass du in der loop() auch andere Funktionen eingebaut hast. Funktionen dürfen nicht innerhalb einer Funktion (hier loop()) stehen.

HotSystems · September 23, 2023, 9:21am

Hallo,
ich habe mir auch noch mal den ersten Sketch angesehen.
Da hast du auch in der loop() eine Funktion eingebaut.
Das kann nicht funktionieren.
Ich vermute, du verwechselst hier die Funktion und den Aufruf der Funktion.

Zudem zeigt der Sketch beim kompilieren dass beim Uno zu wenig dynamischer Speicher zur Verfügung steht. Das kann dein Problem sein.

Welches Board verwendest du ?

stich73r · September 23, 2023, 10:54am

Ich habe einen UNO

HotSystems · September 23, 2023, 10:59am

Und zu den anderen Problemen hast du nichts zu sagen ?
Aber du weißt ja jetzt, wo dein Problem bzw. die Problem zu suchen sind.

stich73r · September 23, 2023, 11:15am

Hallo das habe ich auch gesehen und habe bei der Displayauswahl auf 1_H umgestellt
U8G2_SH1106_128X64_NONAME_1_HW_I2C u8g2(U8G2_R0, /* reset=*/ U8X8_PIN_NONE);
damit ist das Speicherproblem behoben.

HotSystems · September 23, 2023, 11:39am

Ok, das ist alles, was du dazu zu sagen hast ?

stich73r · September 23, 2023, 11:47am

Habe den Code umgebaut nun ist das Speicherproblem behoben.

Zeig doch bitt mal ein Foto von deinem Display mit der fehlenden Anzeige.

stich73r · September 23, 2023, 12:34pm

Also das Problem liegt an der Umstellung von F auf 1 bei der Display defin.

HotSystems · September 23, 2023, 12:43pm

Ok, wenn du das so schreibst.
Dann dokumentiere bitte mal deinen aktuellen Sketch, so dass wir auch nachvollziehen können, was da genau passieren soll. Und dann formatiere den auch in der IDE mit Strg + t, damit der besser lesbar ist.
Und tausche den letzten Sketch dagegen aus.
Evtl. lässt sich dadurch dein Fehler finden.

Du hast den Sketch leider nicht kommentiert bzw. dokumentiert.
Und warum 18 - 32 ATiny ?
Warum nicht mit entsprechenden ADC's ?

stich73r · September 23, 2023, 2:54pm

Kann Attiny mit einem Sketch beschreiben.
Und die Batteriespannung dierekt als Wert an den Arduino übergeben.
18x12V in Reihe sind 216V evt 36X12V= 432V darum Einzelmessung galvanische Trennung.
