I don't think any code in PBP was posted for 3 or 2 wire interface till now.
I tried to understand the code given on http://www.rentron.com/Myke1.htm.
But couldn't really understand the command sequence. I didn't really get how the RS and E lines of the LCD are being handled.
That's the same book/code/idea I was talking about. I picked up that book back in '01 (give or take a few months). Basically you manually preload a shift register with all the data bits, then the rest of the control bits and the last thing to get 'tripped' is the Enable, all done by a shift register.
Not a new idea by any stretch, but a handy one...
