PCF8574 is a I2C i/o expander. So you'll need to use I2CWRITE.

While i consider it as a real waste of time to control a LCD when you can do it in a snap with PBP LCDOUT, you should, IMHO, consider to use some cheap PIC to do it and use SEROUT, SEROUT2 or DEBUG.

Any PIC with internal OSC (like those dusty 16C505) are just perfect for that. It also give you some extra I/O for LEDs or else
