I want to use the esp32 to do live streaming of the accelerometer data, but the i am getting errors when compiling the example code for the esp32.
the code compiles fine for an arduino nano, but the 5v incompatibility makes it unusable for my devices.
using the provided i2c example for the H3LIS331 on an esp32 produces the errors:

Any help with the compiling would be appreciated. As a sanity check, the esp32 was able to compile and blink the led afterwards, so the standard esp32 libraries seem unaffected?
thanks
