| |
What follows is a long list of fixes and enhancements to the one wire system, and even some documentation.
I no longer have any deadlocks, a thread was eliminated (along with its one second wakeup interval), the cpu and time overhead are much reduced for one wire accesses. The time for the ds2490 to read a temperature sensor went from 3.91 seconds (.002s user, 3.001s system) to 0.860 seconds (0.004s user, 0.004s system). I also added support for the strong pullup to provide more current when requested.
Note, only the documentation patch 29 differs from the previous set of patches sent July 11th.
