(...) I'm having trouble downloading the patched firmware. Robolab doesn't have a .lgo file anywhere in the program directory structure, so I don't have a filename to replace with the patched file. Downloading in Robolab seems to work, but I see no (...) (22 years ago, 29-Nov-03, to lugnet.robotics, lugnet.robotics.rcx.robolab)

(...) Wow, that's far more than I expected! And thanks for the detailed explanation. I may have to look at it tomorrow - my daughter's birthday is today. <snip> (22 years ago, 29-Nov-03, to lugnet.robotics, lugnet.robotics.rcx.robolab)

(...) My arguments would be: 1. The firmware/sensor arrangement is _broken_. Fixing it should be legal. 2. The FIRST rules permit using different firmware implicitly, because they permit using RIS or Robolab, which requires different firmware. 3. (...)

Hello Dick, Looks great, but it doesn't seem to work well here: - counts up 2 by 2, but counts down correctly one by one - loses count, especially when counting up. My tests were done with a brand new, unmodified rotation sensor. I mounted a wheel (...) (22 years ago, 29-Nov-03, to lugnet.robotics, lugnet.robotics.rcx.robolab)

Following up from my earlier post, I have completed a firmware patch for the rotation sensors. This post contains the patch with installation instructions followed by a technical description. A long post but hopefully more than made up by the value (...) (22 years ago, 29-Nov-03, to lugnet.robotics, lugnet.robotics.rcx.robolab)

(...) All this talk of patching firmware to correct for problems in rotation sensor readings is very interesting, but I think you may be approaching the problem a bit too directly. First, if the competition rules specify the programming environments (...) (22 years ago, 28-Nov-03, to lugnet.robotics.rcx.robolab)
