| | | In light of the underwhelming lack of response to my LEGO IR post, maybe I need to clarify a little: The RCX tower and the LEGO remote control (#9738) both transmit a 38kHz carrier which is modulated at a 2400bps rate. The encoding is 8 data bits, (...) (25 years ago, 17-Sep-99, to lugnet.robotics.rcx)

The RCX with take an RCX message and treat it as a message. The stuff from the remote is treated (...) (25 years ago, 17-Sep-99, to lugnet.robotics.rcx)

What the d2 opcode did was discovered a while back when the firmware was disassembled, but people could only guess as to why Lego put such an opcode into the RCX. It was never connected (...)

| | | | (...) Do you want to connect the PIC to the IR tower to receive signals from the Lego remote control, or do you want to build your own IR receiver, and attach the PIC to that? The encoding of the IR is pretty simple. The IR tower contains a circuit (...) (25 years ago, 17-Sep-99, to lugnet.robotics.rcx)

I envision a Sharp GP1U581Y IR receiver driving a PIC. The PIC will (...) (25 years ago, 18-Sep-99, to lugnet.robotics.rcx)
