I purchased an LCD !2C interface with a PCF8574 chip. I can't use the built in I2C commands because I have to be in 4 bit mode. Any example code would be much appreciated.
Very Frustrated after 3 days of trying.

    Allan, welcome to the Parallex Forums!
    Can you provide a link to the "LCD I2C interface" ? Also post what you have programmed so far and where you are having problems. Without knowing the details of the interface and the "built in I2C commands" there is very little help we can provide. All we know is that you have an interface (unknown) and a PCF8574 I2C Port Expander chip.
