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)

(...) This probably is an issue of leaving your Port object around after you're done using it. You have a memory leak in each routine, because you call 'new RCXPort();' without ever calling 'delete port;' on the object. You should definitely call (...)

Hi guys, First of all, thanx Brian, but I managed to solve the weird firmdl.bat problem by fooling around with different batteries and IR range levels. Secondly,I'm trying to send data packets to the RCX through java methods called from a C++ (...) (21 years ago, 28-Nov-03, to lugnet.robotics.rcx.java)
