Hi,
I'm a student and I'm working on my first project with a DDS. My project consists in making the communication between the DDS and a MBED controller via SPI. The pins I have been using to try it are:
AT THE U5 IO HEADER:
-IO_RESET
-CSB
-SCLK
-SDO
-SDIO
AT THE U6 IO HEADER:
-IO_UPDATE
AT THE U9 IO HEADER:
-EXT_PWR_DWN (grounded)
About the IO_UPDATE and the EXT_PWR_DWN I didn't understand their behavior. Can Someone help me?
Thanks for the attention,
Vinicius
