ssd1306_128x32_i2c.ino

[shalikashvili]

• Arduino board: QtPy (M0) (n/a, issue should occur on any applicable board)

• Arduino IDE version (found in Arduino -> About Arduino menu): 1.8.13

• List the steps to reproduce the problem below Load and run the example: https://github.com/adafruit/Adafruit_SSD1306/blob/master/examples/ssd1306_128x32_i2c/ssd1306_128x32_i2c.ino

• Behavior Code fails to open ssd1306 device and freezes

• Probable cause Line 36 reads: Adafruit_SSD1306 display(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire, OLED_RESET);

Note: The above code has no effect, and fails to instantiate an Adafruit_SSD1306 object instance

The line should read: Adafruit_SSD1306 display = Adafruit_SSD1306(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire, OLED_RESET);

also needs #include <Adafruit_I2CDevice.h>

The analysis of line 36 is incorrect. Whatever the problem is, it's not the syntax of the variable definition.
