OLED Function call error after Arduino 1.8.10 install

Q&A Forum › Category: Arduino › OLED Function call error after Arduino 1.8.10 install

vgershman asked 6 years ago

Hi,
I installed new version of Arduino 1.8.10 (going from 1.8.7) and now i get an error message “no matching function for call to ‘Adafruit_SSD1306::Adafruit_SSD1306(int, int, TwoWire*, int)'”.
I copied Adafruit_SSD1306 and Adafruit GFX directories to C:\Docs\arduino-1.8.10\libraries, but still get an error.
What would be the fix for that?

Thanks

I looked at ESP32 Tutorial “Adafruit_SSD1306 display(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire, -1);” and and removed “-1” from the function call. Now i get a new error: “invalid conversion from ‘TwoWire*’ to ‘int8_t {aka signed char}’ [-fpermissive]”.

I got it. I had a copy of old Adafruit_SSD1306.h in my .ino directory. One i removed it , the program compiled.

Sorry to bug you 🙂
