I2C_Demo fails to compile

[pictorf]

I'm using a MKR1000, and tried for UNO aswell. I made the modifications indicated in previous issue #0afd522, both in I2C_Demo.ino and in ssd1327.cpp but got a this error message : ` C:\Users\xxx\Documents\Arduino\libraries\SSD1327\src\ssd1327.cpp: In function 'void oledWrite(unsigned char*, int)':

same on esp32 (without modifications), example doesn't compile.

I also cannot get it to compile with Adafruit Feather M0

Hey guys, FYI, it works with BitBang_I2C v1.3.0 👍

I am trying to get this to work on a Arduino nano V3, so i wired the A0 and A1, VCC and Gnd, set the jumper to select I2C but no Luck, which pins did you use to get it working ? Even added pullup resistors.
