go-bsbmp's Issues

panic: runtime error: integer divide by zero

I've got an error:

Please create a release

This project is packaged for Debian: https://tracker.debian.org/pkg/golang-github-d2r2-go-bsbmp

There are no releases to track. So it is unknown when we should update the package and if it is safe to update. Please create a first release. In case you are unfamiliar with it, you can read about versioning here (since the version number have a meaning):

BME280 adapter does not correctly read 2nd coefficient

At line https://github.com/d2r2/go-bsbmp/blob/master/bme280.go#L188, I was expecting to see use of the const COEF_PART2_START, but instead found a 2nd use of COEF_PART1_START.

I don't really understand the datasheet page 22 yet, but did want to raise the question.

Incorrect altitude reading

Hello,

I'm doing a quick test with my BMP388, and it displays
INFO Altitude = -24135.46 m

Am I reading it correctly? My altitude is around 156m

Thanks,

(here is the full output:)

Debug level logging annoying

Can logger be set manually? Seems like you left it at logger.DebugLevel. Prints out a LOT of stuff I don't need.

see logger.go
