Hello,

I'm having some trouble with an LPS33HW. It only responds to a single WHOAMI message after powerup or MCU reset (ie via the NRESET line)0690X000008j1lJQAQ.png

    Hi, is your clock working in the correct way for the multi byte SPI? Could you share also the SPI CLK line pattern in your analyzer? You could check if other register such as for example PRESS_OUT_XL are working well, varying on multiple readings. Regards
