Have tweaked the DATAUS and can see pretty much all the characters, cheers.

I'm slightly embarrassed but I'll fess-up. I'm still having a problem with the back-light.

The display pdf shows the Anode / cathode on pins 15 / 16 with the current as below:

With B/L ILED VLED=5.0V -- 72 80 mA
So I'm thinking at 5v with 75ma a 60 ohm resistor on pin 15, pin 16 ground should do it.

I always thought LED's worked on about 25ma, must be a big LED inside then?
