I am using Nucleo F767ZI with SPI interface to ASM330LHHX sensor.
I am using example code from https://github.com/STMicroelectronics/STMems_Standard_C_drivers/blob/master/asm330lhhx_STdC/examples/asm330lhhx_read_data_polling.c
After a couple of seconds "asm330lhhx_xl_flag_data_ready_get" allways returns 0.
After power off and power on I get a couple of readings but then again nothing.
What am I doing wrong?
