Hi,
I'm trying to get the SPI interface with the ISM330DHCX to work but it seems that the SDO pin can't reach logic high levels.
The above has SCL in blue and SDO in red.
CS in blue and SDO in red.
SCL in blue and SDI in red.
Above is my hardware setup, vdd and vddio is hooked up to 3.3V on the Nucleo.
I've been able to get this to work with I2C but haven't with SPI. Any help or advice would be appreciated

Connect MISO to MISO, verify SPI is working correctly.
Verify connections between nucleo and breakout board. List them here. A bit hard to trace where the wires are going.
Should be:
CS -> CS
SCK -> SCK
MOSI -> SDI
MISO -> SDO
Verify board power.
