Hello again,
Thank you again. I disconnected the SDO pin (keeping SDI and the clock connected) and everything works fine, I got the data from the EEPROM as expected. I double checked that SYNC was high, and at the very moment I connect the DAC SDO pin, I do not get the data properly, just 0s.
I am pretty sure that the SDO pin is keeping the MISO line low, but I do not know why.
Regards,
Javi
