SPI control of AD5231 digital pot

[PaulG.]

I'm having trouble getting this to work. I get 000 data response. If I could just get one command working I should be OK. I wrote the command generator using the AD5231 truth table as a visual reference, figuring that would be easiest. Any ideas? Thanks in advance.

There are a few things that I notice:

You have a clock frequency of zero (0).

I think the device is CS "Active Low".

The frame size needs to be 3 [bytes] as far as I can tell.

For further help when using LINX, I highly recommend posting in the LINX forums.
