Communicating SPI with AD5293

Hi thanks to let me participate in this forum.
I have been trying to establish SPI communication with Arduino UNO and MKR100 wifi, using all the trick on the many article I read. At this point I have no a clue in how to make it happen.
I used a logical analyzer, the commands I send look right but the chip doesn't respond.
Please, let me know what information you need from me.
I hope someone can enlighten me and get it work.

Thanks
Aldo Grossi

Please, post your codes that you have tried with Arduino UNO.

Post a wiring diagram. The MKR1010 is a 3.3V device but the UNO is a 5V device. You must not connect them directly, you have to use level converters.

Thanks, for helping me.
I am attaching the Arduino code and the schematic.
Thanks

  SPI.setClockDivider(128);// Set Clock Rate

Set the clock divider to 4 or 8. The chip is more than fast enough to read the signal.

I used a logical analyzer, the commands I send look right but the chip doesn't respond.

How do you know? You don't check the RDY signal.
