(...) As far as I can tell, legOS has some really strange bugs. I've learned to take it for granted that some programs (without warning) will just crash and lock up the machine. This is unfortunate, but I've never found a pattern to them so there is (...) (24 years ago, 21-May-00, to lugnet.robotics.rcx.legos)

(...) lnp does a checksum and throws away bad data. I think it is a 1 byte checksum so 1 out of 256 errors gets through anyway. There is no retry so timeout and retry has to be handled by some higher level code. (24 years ago, 21-May-00, to lugnet.robotics.rcx.legos)

| | Very strange problems

Hi! I am experiencing some very strange problems when programming my RCX. Sometimes (too often) the RCX just locks up when I run my program and I have to remove the batteries and reload the firmware. I have now found that very small changes in my (...) (24 years ago, 21-May-00, to lugnet.robotics.rcx.legos)

(...) I have run into this too, Jerry. A few especially bothersome noise sources include video cameras, security systems, and remote controls. You might consider covering the RCX and tower with a box or towel... I'm glad the terminal emulator works (...) (24 years ago, 21-May-00, to lugnet.robotics.rcx.pbforth)

I think my problem is bounce back noise. I doubled checked the port settings, started with a fresh set of batteries, made sure I had a clear buffer, but what made the difference is where I am doing my programming. I'm working off of a laptop, and (...) (24 years ago, 20-May-00, to lugnet.robotics.rcx.pbforth)

Did anyone ever write the wrapper to allow motor_dir(motor_label x, MotorDirection dir) or some such? There was a variant of it way, way back (0.1.5?) but I don't see anything like it in the current CVS code. Anyone? Anyone? -Luis ---...--- "Going (...)

Sometimes the message is not recieved but when it is, I have never seen any errors in the transmission. Am I missing your point? Second, (...) (24 years ago, 20-May-00, to lugnet.robotics.rcx.legos)

(...) The RCX uses a special packet protocol which involes a lot of binary (non-ASCII) bytes, so controlling it with Hyperterminal won't work very well. Your best bet is to either write your own code to send the packets of the serial port or just (...) (24 years ago, 20-May-00, to lugnet.robotics.rcx.nqc)

(...) A good rule. I just know I'm going to need fast so I am planning ahead. Somehow I'm usually at the bleeding edge of trying to squeeze everything possible out of limited hardware.

(...) No there is not. That being said, it's pretty easy to write one...if you have the time. I fiddled around with it a bit and then gave up since the GNU tools worked pretty quick. It was strictly a time/value exchange. From bitter experience, (...) (24 years ago, 19-May-00, to lugnet.robotics.rcx.pbforth)
