Hi. This image from AD (link below) seems to show a direct connection between a Blackfin and a AD5933/34 EVAL board (perhaps via I2C?). Two Qs:
a) Is a direct data connection actually do-able ? The array of connections at the top right appear unconnected on the schematic.
b) The Eval board has a different layout from mine (AD5933EBZ) - among other differences the board in the image has 5 pairs of screw terminals, mine has only 1 pair. Did a feature for a direct i2c connection exist on an earlier board design ?
