Reference Design LogoThis reference design demontrates the techniques necessary for generating long duration timeouts. Timeouts of 2, 4 8 or 16 seconds are demonstrated. The code for performing these kind of timer functions is useful when implementing functions such as watchdog timers, or when monitoring a long or complicated sequence of events.

Features

  • Sequences/Toggles LEDs using 2, 4, 8, and 16 second duration timers
  • Demonstrates detection of events and triggering or ending sequences
