Thanks Ran - that's why I never could figure it out. It was sold to me as "serial" and I could never figure how to make it work. With your comment on the "variant of SPI" tells me why I can't use it. Maybe "someday" I'll know enough about this stuff to use them.
I've got 4 of them (they were cheap - $1 each?). If you can make one work I'd be happy to send anyone (USA due to shipping costs) a freebie.... for sharing knowledge:)
