I think I see the issue now. I ran i2cdetect (-y 0 and 1) and it could't find the lcd in either case. Originally I thought this was because the I2C functions weren't enabled. I'm connected directly to the pins (using this guide http://joey.hazlett.us/pine64/pine64_pins.html) and I used a simple GPIO and LED setup to verify that they work. SMbus is installed it just seems that I2C tools can't see the LCD screen. I'll see if I can find another I2C device to test it on for comparison.
