Hi,
using the Navio+ code examples I read data from an MS5611 barometer using the I2C interface. Interestingly the pressure readings differed when reading through the Python code as compared to the C++ code by about 6 mbar (e.g. 1000 in Python and 1006 in C++). By comparing to another barometer, it seems that the C++ readings are correct,
Both measures were stable over time. Another curiosity was that when repeatedly reading thorugh Python the temperature increased steadily to about 30°C, whereas when reading through C++ code the temperature was stable or decreasing a bit. I checked that the postprocessing of the raw values is not different between the Python and the C++ code. So my guess is that it has something to do with reading the I2C bus. Any ideas?
