Hey everyone,
I am new to Analog Eval boards and bought the EVAL-AD5676RARDZ to control 8 channels from the DAC. 
Since it has an Arduino Interface, can I just use it as a shield and attached it on top of a regular arduino? Or is it not compatible and Need the SDP-K1 board?
If not, I did solder some leads to the SPI_PMOD and wired up the Arduino.
I have pin PMOD_V connected to 3.3V
GND to arduino GND
SCLK to CLK of Arduino pin
SDIN to MOSI line of Arduino pin
and SYNCb to cs from arduino Pin
I am having trouble sending out the 24 bits of data to the Chip. I tried following the guide from https://wiki.analog.com/resources/eval/user-guides/dac/eval-ad5676r-ardz
and of course reading the datasheet.
I Left all the jumper cables as default.
I am powering the P8 pins using the Arduino 5V.
I am doing a simple command to the eval board.
My SPI settings are default. So I just used SPI.begin();
digitalwrite(slaveSelectPin,LOW);
spi.transfer(0x30); //this selects command 0011, and channel VOUT0
Spi.transfer(0xAA); //this is the first 8 bit of the 16 bit value
SPI.transfer(0xAA); //second set of 8 bits of 16 value
digitalwrite(slaveSelectPin,High);
I chose 0xAAAA as the 16 bit value to easily read from Logic software
I am using the LOGIC Logic analyzer and my timing diagram is way off.
Any help would be appreciated it.
