Hello Don, (...) firm0309.lgo is firmware from RIS 1.5, while firm0328.lgo comes from RIS 2.0. Maybe RIS 1.5 can't download 2.0 firmware, never tried that... (...) I suggest you download BricxCC from (URL) and use its download utility (located in (...) (21 years ago, 29-Nov-03, to lugnet.robotics, lugnet.robotics.rcx.robolab)

(...) 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 (...) (21 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> (21 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 (...) (21 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 (...) (21 years ago, 29-Nov-03, to lugnet.robotics, lugnet.robotics.rcx.robolab)

Please help. I just recently got a Sharp GP2D12 ir distance ranger plus RCX interface device from mindsensors. It is pretty cool, however I am getting alot of flucuation in the readings and in turn I think that i am losing out on range. The maximum (...) (21 years ago, 29-Nov-03, to lugnet.robotics.rcx.legos)

(...) Hi Chris, Thanks for your reply. You're reply confirmed my suspicion about leaving the port object lying around. I think I'll try your first suggestion of 'deleting' the port object at the end of each routine. I hope you dont mind me asking (...) (21 years ago, 29-Nov-03, to lugnet.robotics.rcx.java)

(...) 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 (...) (21 years ago, 28-Nov-03, to lugnet.robotics.rcx.robolab)
