I am building a Sanguino now, need more memory and more digital/analog pins.
You can save one analog pin by using only one pin for chip select. Comment out all occurrences of CSEL2 in the library, and feed CS2 on the LCD by the inverse of CS1. I used a 7400 for this, works fine.
(Btw. this does not affect the need for a longer enable pulse. It doesn't matter if I use the 7400 or the original method.)
