SPI SETUP USING USER DEFINED

MICROCONTROLLER

Once a different platform other than the SDP-K1 is used, power up

the digital input side of the ADP1034 by 3.3 V.

It is possible for users to control the AD74115H by using a user de-

fined microcontroller. The SPI is provided via the Arduino-compati-

ble shield pins. The Arduino connector pins, which are important for

proper function, are encircled in red in Figure 19. The RESET pin

must be controlled by the general-purpose input and output (GPIO)

or be tied to the high level. Otherwise, the EVAL-AD74115H-ARDZ

is held in a reset state.
