Hi Andy, > 5. Rx and IR Learn both use the same external hardware. Not > coordinating Rx with Learn mode in the same driver, will prevent Learn > operation from working.

There's not really any infrastructure in Linux that maps to the Zilog's "learning mode" functionality. Usually I would just tell users to do the learning under Windows and send me the resulting .ini file (which we could then add to the database). I had planned on getting rid of the database entirely and just converting an MCE compatible pulse train to the blasting format required by the Zilog firmware (using the awesome work you sent me privately), but the fact of the matter is that nobody cares and MCEUSB devices are $20 online. > I'm glad someone remembers all this stuff.

I probably put about a month's worth of engineering into driver work for the Zilog, which seems extraordinary given how simple something like an IR blaster/receiver is supposed to be. I guess that's the fun of proving out a new hardware design as opposed to just making something work under Linux that is already known to work under Windows. > I never owned an HD-PVR. I'm sure I have a spare or two if you really want one (not that you have the time to muck with such things nowadays). :-) The HD-PVR was a bit of a weird case compared to devices like ivtv and cx18 because it was technically multi-master (I2C commands came both from the host and from the onboard SOC). Hence you could have weird cases where one would block the other at unexpected times. I2C commands to the Zilog would hold the bus which would delay the onboard firmware from issuing commands to the video decoder (fun timing issues). There was also some weird edge case I don't recall the details of that prompted them to add an I2C gate in later board revisions. Devin -- Devin J.
