ADXL355 OverflowError #688
Description
Hello,
I just ran the examples/adxl355_example.py on my Raspberry Pi Model 4B, but got this OverflowError:

When I separate the variable declaration and print, I got this error:
Data using buffered rx(), raw:

I was able to bypass it using:
import numpy as np
...
my_acc._rx_unbuffered_data_type = np.int32
my_acc._rx_data_type = np.int32
raw = my_acc.rx()
