(...) Your version 3 is also great! When NQC 2 is released will the NQC help be put back in? I thought it was real handy addition on those long nights. --- DonC donc@cccd.edu (25 years ago, 8-Sep-99, to lugnet.robotics.rcx.nqc)

(...) I read the sheet as saying the MINIMUM load is 125K, and the block diagram indicates a buffered output. It would be a good idea to buffer the output, but may not be strictly necessary. The bit about the reference being 20uA capable is correct, (...) (25 years ago, 8-Sep-99, to lugnet.robotics.rcx)

Here's the link to the pyro sensor (URL) The schematic indicates that the reference moves relative to the output... I think the reference and output terminals are mislabelled. Given that they are mislabelled... The reference output has a 20uA max (...) (25 years ago, 7-Sep-99, to lugnet.robotics.rcx)

Just because people want some more traffic in this newsgroup and to quantify the statement of Dave Baum, RcxCC version 2.3 was downloaded close to 3000 times from my web site up to now. Mark Overmars (...) (25 years ago, 6-Sep-99, to lugnet.robotics.rcx.nqc)

Yes it is slow, if you count 1/2 a second slow, but not horrible. The big problem comes with control. Finding neutral again. NQC to the rescue. I find its better for this application than the RIS software. More open for creating servo control loops. (...) (25 years ago, 6-Sep-99, to lugnet.robotics.rcx)

You mean you use the red motor/switch combination as a sort of 'electronic' fuse? Oh, right. While I'm typing I suddenly see what you mean. You use an external power supply for the motors. Clever. Isn't the switching a little slow using the (...) (25 years ago, 5-Sep-99, to lugnet.robotics.rcx)

The best way to avoid high current running thru the brick is to control a small red motor which drives one of the polarity switches which is hooked up to a battery pack and that in turn runs the main motors. We had this problem at the LEGO (...) (25 years ago, 5-Sep-99, to lugnet.robotics.rcx)

MJ, The RCX itself does not need a lot of power. However, if you're going to run 2 motors off each output port (a total of 6), 200 mA won't be enough. I expect the motors to draw at least 100 mA each. Even more when stalled. Maximum power to be (...) (25 years ago, 5-Sep-99, to lugnet.robotics.rcx)

(...) I second that! I tried using the "native" language and its limitations baffled me. I never got a program downloaded. I jumped straight to NQC and have done several now. Good work Dave! DLC (25 years ago, 5-Sep-99, to lugnet.robotics.rcx.nqc)
