 | | Swan firmware crash!
|
|
Hi. I've installed new NQC and BRICXcc to test new functions in fast firmware by Dick Swan. I wanted to see if the new 1/1000th second resolution could let me drive a servo. When I try to use the SetMotorPower128 command, compiler is ok, downloading (...) (19 years ago, 19-Jul-05, to lugnet.robotics.rcx.nqc)

(...) Hi John I've fixed the problem. I tracked it down by commenting out parts of my program. Luckily I started on the function containing the problem So I found it very quickly. Solving the problem took longer though. As you can see below I've (...) (19 years ago, 16-Jul-05, to lugnet.robotics.rcx.nqc)

(...) Can you please email me the NQC source so that I can generate the listing to see if possibly the compiler is generating invalid code? John Hansen (19 years ago, 16-Jul-05, to lugnet.robotics.rcx.nqc)

(...) I've got the flashing five problem as well, and it's really annoying, I spent most of my Friday in vain trying to fix it. I thought/think it's a stack overflow problem, but after serious optimising of my program It's made zero difference. (...) (19 years ago, 16-Jul-05, to lugnet.robotics.rcx.nqc)

I have updated the NQC FAQ with a description of how to fix a USB Tower problem that many users have experienced when downloading a program via NQC. Many users have reported that they get a "Compile Failed no (or invalid) reply from RCX" error when (...) (19 years ago, 29-Jun-05, to lugnet.robotics.rcx.nqc)

I have released NQC version 3.1r2. The only change from 3.1r1 is a fix to the Spybot FindWorld API function. (URL) Hansen (19 years ago, 10-Jun-05, to lugnet.robotics.rcx.nqc)

I continue to work on getting BricxCC ready for a new official release. My sincere apologies for not having one out at the beginning of the year as I had originally planned.

(...) Neither of these work, although the second one does introduce a temporary for everything except for the 0 part. It will result in the display sometimes showing a value of zero. NQC tries really hard to use as few variables as it can so you (...) (19 years ago, 5-Jun-05, to lugnet.robotics.rcx.nqc)

(...) Thanks for the ideas! Actually these yielded some interesting results: a = 0 + ((x * 100) + y); occasionally yielded 0 (as expected), but never yielded anything other than 0 and the correct value (that I saw). a = ((x * 100) + y); and a = (x * (...)

(...) You may be able to work around this by using parenthesis (untested). a = ((x * 100) + y); or you might try a = 0 + ((x * 100) + y); John Hansen (URL) (19 years ago, 5-Jun-05, to lugnet.robotics.rcx.nqc)

I have a program with a setup routine for calibrating light sensors. During the setup routine, it does: SetUserDisplay (a, 2); Then in a loop, reads the values of 2 light sensors into x & y, averages the readings and then does: a = x * 100 + y; to (...)

(...) Rafe, I suggest looking on eBay for an old laptop. By old, I'm talking P100MHz w/ 32-64MB RAM; NQC doesn't require a lot of horse-power (I'm not sure about Bricxcc). For USB, you'll need something capable of running Win98 (P66MHz w/ 32MB (...) (19 years ago, 30-Apr-05, to lugnet.robotics, lugnet.robotics.rcx.nqc)
