Hi,

 

I'm tying to communicate the SPI0 with a Digital potentiometer AD5293, I send it the commands from SPI0 but when the digital potentiometer sends me its status I can't read in the POP register, It appears empty but I see the correct data in the oscilloscope that the digital potentiometer sends me. When I go to see the value in POP register its content is empty or the value or data isn't correct. When I'm debugging the code first I send a command to write the resistance for this Potentiometer, second I hope to receive the correct data that it sends me but this isn't.

 

What is happening with the POP register?? or How I can fix it? I wait for yours answers.
