Hi folks,
I’m trying to read from the H3LIS331DL over SPI, but it is responding with all zeros when I try to read the WHO_AM_I register.
I desoldered the CS pad, so it should be starting in SPI mode. I’m using CPOL=1, CPHA=1 (data on MOSI at leading edge, MISO on trailing edge).
It looks like it’s responding to the read request, but holding the line at zero. How can I diagnose the problem? Here’s a screen shot of the transfer.
