I'm using the evaluation board in an "external connection-USB" configuration (pg. 4 of 16 in EVAL-AD7746EB datasheet) with the accompanying software to test my AD7746 application. I'm trying to get the capacitance output from a surface mount capacitor as a quick test, but I'm getting "Error! No Data Ready from the part". I have the SCL pin from the eval board wired to the SCL pin on the CDC, SDA on the board to SDA on the chip, and RDY from the board to RDY on the chip. Any idea how to wire up the capacitor to measure my capacitance and eliminate the error?
