Thanks Jan.

I have been though the data sheet and the ST forums trying to understand the PSD module. I was hoping that I was not going to need to geting to it, since as you said it can get confusing.

I understand the basic ideas of chip selects and the page register, its just how to use them correctly and to do what I want them to do that I get lost. I use CAPS, rather than PSDsoft since it is a little simpler to use. I could never find any resources that would tell me how to use all the equation setups.

But as you suggest I will dig in a little more. I will come back if I have more questions.
