Description

This MotoHawk™ block is used with a [FrequencyInput.html Frequency Input] block that is operating in the "Provide Trigger After N Pulses" mode to set the number of pulses to observe between triggers (N). This block is especially needed when the [FrequencyInput.html Frequency Input] block has been located within its own [FreqencyInputTrigger.html Frequency Trigger]. because the [FrequencyInput.html Frequency Input] block won't execute until there has been an edge, but the default number of pulses is zero on creation and so no edges can be observed. The set block provides a mechanism to set the number of pulses to a non-zero value from within another thread of execution (trigger). Most commonly this block would be placed in a start-up trigger if the pulse count was to be constant or within a time domain trigger if the pulse count will change at runtime.
