Issue Details

I would like to be able to emulate more than one I2C address on the NI-8452 acting as a slave.

Is this possible to do with using only one NI-8452?


Currently this isn't possible. The USB-8452 isn't able to claim more than one I2C address on the bus. Additionally, the address is tied to a session and the device can only run one session at a time, so you have to use mutliple NI-8452 to simulate multiple I2C slaves.
