Reefhermit

Is this supported or possible with the Hardware i/o library?

@Reefhermit Those aren't currently implemented, but they should be doable, at least from what the Linux i2c infrastructure offers (would still need to check if the device driver actually handles those).

Do you have a specific device or situation where you would need to use those?

Reefhermit

Yes, of course. I am using the rpi3. I found a Linux command line, or should I say three command lines that somehow activate the repeated start.

@Reefhermit But which peripheral do you need the repeated start for?
