I want to control the AD9910 Eval Board with SPI.

 

Set it

1. Eval Board Jumper Set -> External Control Setting

   a. W1, W2, W4 Disable

   b. W3, W5, W6 Removed

 

2. Connection MCU to Eval Board

   a. ATmega8 #MOSI  - Eval Board Header U5 #SDIO

   b. ATmega8 #CLK    - Eval Board Header U5 #SCLK

   c. ATmega8 #SS      - Eval Board Header U5 #CSB

 

3. transfer data

(This data is the data value observed with oscilloscope spoke during GUI connection.)

Hex Code

   83 00 7F 7F

   9F 00 40 00 01 00

 

   04 FF FF FF FF

   00 00 00 00 00

   01 00 40 08 20

   02 1D 3F 41 50

   03 00 00 7F 7F 

 

I tried setting it up but there is no change.

Is there a value that is not set well?( H/W connection or F/W programed )
