Hi, My sketch that used Adafruit_CharacterOLED is suddenly generating compiler errors. I've now uninstalled the Arduino 1.8.12, deleted its installation folder, the libraries folder in My Documents\Arduino and the Arduino15 folder in AppData\Local.
I've reinstalled 1.8.12 and Teensyduino 1.52 and downloaded Adafruit_CharacterOLED-master.zip from https://github.com/ladyada/Adafruit_CharacterOLED and added it from Include Library.
Just using the provided example sketch HelloOLEDWorld gives the same errors my own sketch was giving:
F:\Documents\Arduino\libraries\Adafruit_CharacterOLED-master\Adafruit_CharacterOLED.cpp:66:101: warning: default argument given for parameter 3 of 'void Adafruit_CharacterOLED::begin(uint8_t, uint8_t, uint8_t)' [-fpermissive]
void Adafruit_CharacterOLED::begin(uint8_t cols, uint8_t lines, uint8_t character_set = LCD_JAPANESE)

Can anyone please tell me either what's changed to make this fail or what I can do to fix it? Many thanks
I've reinstalled 1.8.12 and Teensyduino 1.52 and downloaded Adafruit_CharacterOLED-master.zip from https://github.com/ladyada/Adafruit_CharacterOLED and added it from Include Library.
Just using the provided example sketch HelloOLEDWorld gives the same errors my own sketch was giving:

Sketch uses 15024 bytes (1%) of program storage space. Maximum is 1048576 bytes.
Global variables use 4948 bytes (1%) of dynamic memory, leaving 257196 bytes for local variables. Maximum is 262144 bytes.
Can anyone please tell me either what's changed to make this fail or what I can do to fix it? Many thanks
