Truck back online
06/07/2011 - 10:43 AM
I did a kernel upgrade on Saturday.
When the server rebooted with the new kernel fine I did not expect any problems and did not test much.
Today I noticed that the truck has not been moving since Saturday - very unusual.
The move commands did not go through to the hardware. First I expected a hardware problem - after all the parts used are ~13 years old.
Later I found out that with the server upgrade, support for the parallel port was not loaded.
Adding the lp module to this OpenSUSE 11.4 server solved the problem.
Testing revealed that the truck is reversing much too fast, unloading all blocks before moving them up to the tipper.
I changed the script to reverse slower -> loading the truck should now be easier than before.
