| | Decoding the LEGO IR remote control
|
| Hello All - - I'm interested in using a LEGO IR remote control to control other things besides the RCX. Has anyone here done any PIC development along these lines? I would like to use a PIC to decode the output of a Sharp GP1U581Y and convert the 16 (...) (25 years ago, 17-Sep-99, to lugnet.robotics.rcx)

Additional parameters could make the format be comma-delimited, (...) (25 years ago, 24-Sep-99, to lugnet.robotics.rcx, lugnet.robotics.rcx.nqc)

| | decoding a message sent by an RCX

| hiya, I have been working on an idea to extend the number and type of devices that the RCX can control. I started with the idea of encoding serial data on one of the motor lines and decoding that in a PIC to do <stuff>. However, because working at (...)

A "simple" (hehe :-) 8 bit Input / Output expander would be very, very nice. (...) (25 years ago, 4-Sep-99, to lugnet.robotics.rcx.nqc)
