(...) Sorry about the mixup. I thought I'd tried capturing non-compiler errors with a redirect and it hadn't worked. But trying it just now it definitely does work. BricxCC is already capturing the compiler errors via the -E option. I am trying to (...) (24 years ago, 15-Jan-02, to lugnet.robotics.rcx.nqc)

Hi John, I just got a new computer and tested your program on a AMD 1.333GHz Athon (Thunderbird). It works just great! I thank you for the adjustments/adds in your program as I requested. There is just one question left. Since I use to Delphi, I (...) (24 years ago, 15-Jan-02, to lugnet.robotics.rcx.nqc)

Ok, RP4 was fine. I've put a logic tester "MODA" line on the chip (from what I can figure, this is this pin that gets the signal from the stop switch), and it is recieving a signal when I press the stop switch. I verified that the reset pin was (...) (24 years ago, 15-Jan-02, to lugnet.robotics.handyboard)

I have seen several postings about getting NQC working with the USB tower under Linux. I suspect that a few things will continue to be tweaked for a little while, and since I can't build/test the Linux software myself, I am hoping that someone else (...)

On the transmission side you just use transfer_buffer_length (...) (24 years ago, 15-Jan-02, to lugnet.robotics)

Steve, I see your point. I forgot the sensor also responds to gravity. I suspect that the best we can do is a very rough demo of principle, not a practical navigation system. Thanks for your insight! That is what makes this forum so useful. - pete. (...) (24 years ago, 13-Jan-02, to lugnet.robotics)
