Hi,
I’m using bbbmini and i2c oled display (generic 0.96" like this one https://www.banggood.com/0_96-Inch-4Pin-White-IIC-I2C-OLED-Display-Module-12864-LED-For-Arduino-p-958196.html?rmmds=search) developed by @mirkix, until the previous versions - Copter 3.4 and Plane 3.7.1 eveything is working fine, but in beta (ArduPlane V3.8.0beta5 (75f74459) and arducopter the oled display is not showing anything.
there is no error on the console - the display are correctly detected(i2cdetect) at i2c bus @ address 3c.
Regards
