I bought EVAL-AD5383 (obsolete) and I am trying to use SPI to communicate to the DAC.
A little history on my experience using Analog Devices DAC:
I have previously evaluated AD5371 using an eval board and then prototyped a design using microcontroller and SPI communication successfully.
Now with the AD5383; I am not using USB to connect to the DAC or the AD software. I am using header J10 to interface with the DAC using SPI communctions.
My Connections are
GND - Ground to My microcontroller;
BUSY -GPIO pin on my mirocontroller
SYNC - GPIO pin on my mirocontroller
DIN- SPI data in
SCLK- SPI clock
LDAC - GPIO pin on my mirocontroller
LK1 - On
LK4- Position B
S1 - L
S2 - L
S3 - L
S4 - L
S5 - H
S6 - L
I am trying writing 0x00FFFC (000000001111111111111100) to get 5 V on Vout0. I am not getting any output on Vout0 (Vout0=0).
the signals are getting to the dac but the busy pin doesn't get low (i probed it) when i write the to the DAC.
Do I have to write to CLR and RESET? a 24 bit string?
in the AD5371 I had a digital I/O pin to go high or low I don't have that in this board?
