Subject: Using i2c from UEFI driver or application
Date: Wed, 12 Apr 2017 13:44:04 -0600 [thread overview]
Message-ID: <daef0d76-52cb-cedc-3a73-05c204f6db7c@bluestop.org> (raw)
I'm writing an application (it may also end up being a DXE driver) that
needs to access the i2c bus. The issue I'm seeing is that the i2c/SMBus
access protocols etc. seem to be from the PI spec, and my understanding
is that drivers or applications aren't supposed to use PI-specific
functionality. Is my understanding correct, or is there some other way
for drivers/applications to access i2c devices?
