@inglewoodpete
Thanks for the code. On the 28/40X1 the 'hardware' mode SPI I was querying was the
hspisetup / hspiout / hspiin
form, not the
shiftin(spiin) / shiftout(spiout)

I have achieved results with the spiin/out as well but not with the much more efficient hspiin/out.

@BCJKiwi - do you have any idea why with the 18X these commands do not work? the manual says they do but in reality they don't!!

If these commands work on the 18X i think i will achieve POV easily.

Sorry, not worked with SPI on 18X.

spiin/out are supposed to work, hspi are only for X1 parts

The process seems to be to use the relevant sections from the sample code - that was the only way I could get started on the 28X1 but I moved over to i2c for the project concerned BUT SEE HIPPY's POST #27 above.

SHIFTIN, SHIFTOUT, SPIIN, SPIOUT, HSHIN, HSHOUT, HSPIN, HSPIOUT are only supported as commands on the X1/X2 PICAXE's, not on any others.
