Display function is not working

[Rishabh028]

I am trying to display the output of serial monitor in a 1.5 oled display but when i am using display.display( ); it is showing error C:\Users\Rishabh\AppData\Local\Temp.arduinoIDE-unsaved202425-13096-sx2s2m.799bi\sketch_mar5a\sketch_mar5a.ino: In function 'void loop()': C:\Users\Rishabh\AppData\Local\Temp.arduinoIDE-unsaved202425-13096-sx2s2m.799bi\sketch_mar5a\sketch_mar5a.ino:36:13: error: 'class Adafruit_SSD1351' has no member named 'display' display.display(); // Update the display ^~~

exit status 1

Compilation error: 'class Adafruit_SSD1351' has no member named 'display'

Hey so I had a similar problem and there isn't really a straight forward fix if you want to update the display at once with pixel data AFAIK. But I got around the issue with a combination of tft.startWrite(); , tft.dmaWait();, and tft.endWrite();

It's unclear what the actual issue is here. The error message is generally explaining what is happening:

class Adafruit_SSD1351' has no member named 'display'

Why is the call to display() being attempted? It doesn't exist.

So what should i use to display the serial monitor output of arduino ide in 1.5inch oled spi display ?

Can you show an example? I don't quite understand how this can replace this function.

Can someone provide an example sketch code that demonstrates this issue?
