Hi,
I was wondering if there is any problem with using the I2C LCD backpack with Arduino's non- I2C pins. I wrote my own I2C routines some time ago which allow me to use any two port pins on the Arduino Duemilinova and Uno. I prefer not to use the dedicated I2C pins if I can. I just ordered my backpacks so I haven't tried this yet..thus the question.
Thanks in advance.

Re: I2C LCD Backpack
The backpack won't mind. But you will need to do a little library hacking because our Version of LiquidCrystal with i2c support assumes hardware i2c.

Re: I2C LCD Backpack
Ok, thanks. I don't mind adding what I need that will take the place of the backpack's library. The core I2C routines were easy so I just have to add my own basic lcd initialization and command functions using the Adafruit library as guidelines.
Thanks again!!
