I've had a lot to do helping with Picaxe LCD driving over the last (- gasp- !)4 years & have found by frustrating experience that the LCD at the far end is not always the normal reliable Rev.Ed kit that was initially assumed.Argh! Please hence specify EXACTLY what you are using,with perhaps a pix,schematic & driving code, detailing supply voltage etc as well. We can not read your mind!
Just what is this <i>"trying to use an lcd from 18x using the serial chip - I have two brand new ones " </i> ? The 18X will drive a Rev.Ed LCD kit directly without any "serial chips". Have you popped in a MAX232 as well ?? The surest way to test your Picaxe is to of course send some serial out to a PC running a terminal program such as Hyperterminal,or (even easier) use SERTXD & F8. Stan
Footnote: Aside from the Rev.Ed kit,there are several other recognised Picaxe LCD approaches,with those of both Peter Anderson & Hippy being highly thought of.
