Research direction

Start with example.py line 13 and ms5837/ms5837.py line 74, then reproduce the initialization failure while comparing it with the i2cdetect output showing address 76. Determine why the reset write returns the Remote I/O error and document or implement a verified resolution.

Description

Hi,

I am trying to run example.py on a RPi4, but when I do, I get the following error:

Traceback (most recent call last):
  File "./example.py", line 13, in <module>
    if not sensor.init():
  File "/home/pi/ms5837-python/ms5837/ms5837.py", line 74, in init
    self._bus.write_byte(self._MS5837_ADDR, self._MS5837_RESET)
IOError: [Errno 121] Remote I/O error

It appears that the ms5837 is recognized when I run i2cdetect:

i2cdetect -y 1
     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f

50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
70: -- -- -- -- -- -- 76 --

Any ideas why I'm getting this error? Any help would be greatly appreciated!

Thanks,
Jonathan
