I wasn't doing that so all my communications were writes, hence no response from the MPU. Also the communication wasn't working when I had the oscilloscope probes attached as well.
Glad you got it working. I think you're the second person on the whole internet to get SPI working with the 9250... I have so many questions (:
Can you post the register values you use to initialize the 9250?
Do you have to disable i2C on the 9250? If yes, how?
How did you wire the chip?
Can you sample at 8Khz?
What is the SPI mode you're using on the Raspi?
Thanks a lot!
