Ok, I have a Frequency drive for a blower motor and I would like to control it with Picaxe.
Here is the datasheet on a digital pot http://che126.che.caltech.edu/11195c.pdf it is a single channel, 8 pin dip chip.
How in the world do I talk to this thing? I have read virtually everything I can find about SPI interfacing and manual 2 but I just dont get what, and how I am supposed to get Picaxe to make this thing work. is it a ascii string being sent? is it a binary being sent.....what? How do I get picaxe to set the wiper at step #25 or #130 or #222
Please dont post a bunch of links, as I have probably already read it.
A simple, explained, piece of code would help.
I would be ever grateful for anybody that can help me understand this since it is an industry standard.
thanks
