Hello. I have two questions about #include. I am using RCXcc Beta 3.0. 1. How do you specify the default include path. Is there an environment var? 2. When I use the full path (E:\lego\application...\file.nqh) I get an error that says there is no (...) (25 years ago, 19-Sep-99, to lugnet.robotics.rcx.nqc)

(...) They are one and the same. When transmitting, the IR tower just uses the RS-232 TXD line to switch on the 38kHz carrier. It also has some timing circuitry to keep it alive, and an Rx side, but the Tx is painfully simple. You'll probably see (...) (25 years ago, 18-Sep-99, to lugnet.robotics.rcx.nqc)

(...) The Sharp GP1U581Y is a 38kHz receiver that incorporates an amp, a limiter, a bandpass filter, and a demodulator ... outputs a low while receiving an IR signal, a +5V high when not. It does NOT do any decoding. (...) From what I've been seeing (...) (25 years ago, 18-Sep-99, to lugnet.robotics.rcx.nqc)

(...) What exactly does the Sharp IR receiver do? If it uses Sharp's ASK modulation, then you may have a problem. Ideally, what you want is something like a phototransistor to a good preamp, followed by a bandpass around 38kHz, then some sort of (...) (25 years ago, 18-Sep-99, to lugnet.robotics.rcx.nqc)
