It's posible to add support for I2C baro? Like the LPS25HB https://www.sparkfun.com/products/14767 it's small and can be an option for smd boards.

Time critical events like ignition and injection are managed with interrupts. The issue with the standard wire library is that it blocks interrupts for quite some time and therefore messes with the timed events in an unacceptable way.
Not to hijack this thread, but the question comes up every once in a while.
And I can understand this quite well because many I2C components are very affordable. It would be the icing on the cake if we could get this running.
Most topics referring to this are quite old. I cannot say if there have been recent discussions on Slack where I could not find them anymore.
There is a non-blocking alternative I2C library (I believe by Paul Stoffregen). Has this been discussed or tried yet?
