Subject: Simultaneously access to one i2c/dev-interface from different process to different i2c devices
Date: Wed, 05 Nov 2014 09:58:44 +0100 [thread overview]
Message-ID: <5459E6C4.3060107@optimeas.de> (raw)
Hello,
is it possible from different processes to access different i2c devices
on the same i2c bus/adapter using the i2c/dev-interface from userland?
Or can the i2c/dev-interface only ne used from a single process?
How does the simultaneously access to one adapter works for i2c device
drivers inside the kernel?
Do they fail on a simultaneously access, or do they wait until the i2c
adapter is ready/free for use?
Best regards,
Matthias
