of the sensor hardware. Part of the polling process involves signalling the chip then waiting 20 milliseconds. This was being done with DELAY(), which is a pretty rude thing to do in a callout. Now a taskqueue_thread task is scheduled to do the polling, and because sleeping is allowed in the task context, pause_sbt() replaces DELAY() for the 20ms wait. |
