Here's my drawing of the RCX IR transmission circuit (receiver circuit to follow soon): (URL) With the voltages as shown, the RCX is not transmitting. The IR LEDs are powered by a 600mA current sink. I haven't measured for waveforms yet - the (...) (20 years ago, 20-Jan-05, to lugnet.robotics, lugnet.robotics.rcx, FTX)

Folks, I've been fiddling around with how BricxCC and NQC talk to the RCX when using the USB tower. It's because of several users experiencing problems when trying to download programs from within BricxCC (using NQC behind the scenes). Depending on (...)

Here are my drawings of the RCX sensor port and power supply circuits, complete with measured voltages from inside the box. These are averages measured with a DMM, not an indication of peak waveforms. I might use an oscilloscope later if there's a (...)

Hi Tom, Just for my education purpose, I'd like to understand the difference between the "begin" & "end" control boxes at the "Front Panel" window. Although they look identical, they must be different since they failed to wire to the blocks next to (...) (20 years ago, 16-Jan-05, to lugnet.robotics.rcx.robolab, lugnet.robotics.rcx)

(...) It is a leftover from LabVIEW. When you create a sub.vi, LabVIEW reuses the name of whatever is wired to the control/indicator. This behavior makes perfect sense in LabVIEW but much less so in Robolab. FWIW, the names are little more than (...) (20 years ago, 16-Jan-05, to lugnet.robotics.rcx.robolab, lugnet.robotics.rcx)

| | sub-vi begin vs end control
|

Hi, After a sub-vi is created, there are two controls created namely begin and end. Would someone explain why they are backwards? That means, it creates an "end" control linked to the beginning of the sub-vi, while the "begin" at the end. Thank in (...)
