LCD together with ArdOS problems

Using Arduino Displays
#1

We are using a RTOS ArdOS, and we are trying to use the following LCD library: https://codeload.github.com/vanluynm/LiquidCrystal_I2C/zip/master

It crashes when we are using the method setCursor, and we are suspecting the following method to be the reason:
void LiquidCrystal_I2C::expanderWrite(uint8_t _data){
Wire.beginTransmission(_Addr);
Wire.write((int)(_data) | _backlightval);
Wire.endTransmission();
}

Is there any way to work around this, or somehow fix it so it is compatible with ArdOS, or another RTOS?

#2

I'm also experiencing this problem with ArdOS combined with that library. The library works fine when used without ArdOS, but if the library is used within a task in ArdOS, it crashes the Arduino.. I hope someone can help.
