Thanks for the vote of confidence
However, I thought this over, and I think I can make my application work with the PF commands only. I wonder if there is some documentation for the IRSeeker class? (Is this even the right class for the PF commands?) I didn't find anything in the API javadocs or much in the tutorial other than the table listing the class and that it is a subclass of the i2c class. The source code that is bundled with Lejos does not appear to have the source for IRSeeker either, although I may have missed it.
Does the command set for talking to a PF IR receiver through the IRSeeker class allow you to pick the channel (1-4) and the direction (forward, backward)? What about things like continuous command vs set and forget?
If IRSeeker really supports the full PF repetoire, this would be great, since in effect it gives up to 4 output channels and only burns one input channel. Granted, you don't get power levels and closed loop feedback, but for many simple needs, just on/off forward/reverse is quite adequate.
Thanks for listening to all the newbie questions!
