subject: One I2C bus, two programs

Hello all,

I've got a few I2C modules (clock, temperature sensor, etc) that I would
like to access using different programs.

Under Windows the first program accessing certain hardware "takes
possession" of it, causing other programs to be denied access.

The question is: how do I allow multiple programs to access the same I2C
bus, but not interfering with each other ?

Or am I worrying about nothing, and the OS already sequentialises the
request for me ?

Regards,
Rudy Wieser
