(...) In collaboration with Jason Railton I have modified/extended the NBC and NXC API functions for the HiTechnic iRLink device in support of the newly documented Power Function modes as well as the R/C Train IR protocol. I uploaded a new (...) (16 years ago, 1-Feb-08, to lugnet.general, lugnet.technic, lugnet.trains, lugnet.robotics) !

(...) <snip> Nicely done John! Is there a tentative timeframe when NQC for the RCX will be updated to support IR to the LEGO powerfunctions? Dave K (16 years ago, 2-Feb-08, to lugnet.general, lugnet.technic, lugnet.trains, lugnet.robotics)

(...) I doubt that's possible - a bytecode program just can't run fast enough to do the timing for the IR commands, on either brick. The NXT can only manage it because it sends them over a slow comms link to a HiTechnic IRLink sensor, then that (...)

(...) Dick Swan's replacement RCX firmware also does not support directly manipulating the IR led and it doesn't support microsecond timing control. Both of these features would be required in order to send the IR messages to a Power Function or R/C (...) (16 years ago, 4-Feb-08, to lugnet.general, lugnet.technic, lugnet.trains, lugnet.robotics)
