(...) Whoa. Not so fast. My firmdl3 does the job in 44 seconds, not 53 seconds, so I think firmdl4 is a step backwards. :) Just hold on a bit while I finish packing it up. It is almost done, I promise. The new version (firmdl3) will be MPL. If you (...) (25 years ago, 4-Oct-99, to lugnet.robotics.rcx.legos)

Hi Kekoa, I herewith jettison fastdl. - added code to remove parity and disable complements to your stub - split up firmdl2 into nice little modules - figured out how to deal with complement-disabled packets - optimized delays, fixed numerous little (...)

We are planning on solving a physical maze (ie cardboard or plywood.) The plan is to use LegOS to allow C (NQC) capabilities.

I've looked at a couple of traces and it looks like the serial driver just stops receiving data after a certain point. One theory is that something happens (framing error or overflow), which then keeps the driver from relaying more information. I've (...) (25 years ago, 3-Oct-99, to lugnet.robotics.rcx.nqc)
