Maggie, If the EVM still works when connected to the normal TI software, the EVM board should work when connected to a separate microcontroller. Below is my setup. I soldered some pin headers onto the EVM and used jumper wires to connect everything. There are 6 connections. I use /CS, SCLK, DIN, DOUT, VDD, and GND. Starting out, I've left the input pins unconnected. Here's what it looks like from the bottom side of the EVM: I have an intermediate board that I use to connect the Aardvark to the EVM. The Aardvark has a 2x5 set of pin headers, and I connect that to an intermediate board which has a few pin headers to jumper to the EVM: On the bottom side of the intermediate board, there are a few more pin headers that use for the Saleae logic analyzer.
