   (...) in (...) Statement should be right. It's same behavier found in original firmware: (URL) (battery power (cc5a) > 1a2c (6700 mV)) call ROM 1e4a (r6=301b) // clear battery low indicator else if (battery power (cc5a) > 189c (6300 mV)) call ROM (...)

        Re: Is this an error in legOS 0.2.5? —Michael Obenland
   So in the original firmware, the system is shut down if ultra-low battery is detected. If we don't want tot do that, we could change the ">" in the 2nd compare to a "<" to get some hysteresis. Or would it be usefull to stop legOS and do a shut-down (...) (23 years ago, 29-Jul-01, to lugnet.robotics.rcx.legos)

In effect, changing the batteries is equivalent to the (...) (23 years ago, 30-Jul-01, to lugnet.robotics.rcx.legos)
   
        Re: Is this an error in legOS 0.2.5? —Michael Obenland
   (...) Hmmm, yes, you are right. In fact it woudn't make sense. My actual robot uses a little neural net and if battery goes low, the actual data will be sent to the PC to be saved. For this, it would be nice if the RCX makes some noise, I grab it, (...) (23 years ago, 31-Jul-01, to lugnet.robotics.rcx.legos)

   (...) a (...) Maybe, if you wanted to be really flash, when you get the (non-ultra) low battery warning, your robot could start seeking out the tower, and get ready to send the data. Maybe have a light near the tower that starts flashing when it (...) (23 years ago, 4-Aug-01, to lugnet.robotics.rcx.legos)
