Detailed Description

Event configuration

threshold is rise/fall threshold for input data. When set this member for rise in struct scuev_notify_s, counting data if higher than threshold, and fall is vise-versa. count0 is used for prevent chattering. count1 is used for counting continuously input. When configured for rise, SCU processing as follows:

  • Counting higher value than threshold coninuously
  • If counter reached to count0, start actual couning
  • If input data fall less than threshold before reached to count0, then stop and reset counts
  • If total count is reached to count0 + count1, then raise rise event
  • If count1 is zero, then notify when count reached to count0 immediately
  • If threshold or count0 is zero, configuration is ignored
