UARTTrigger exact trigger point


The software documentation indicates that UARTTtigger can be used to generate a trigger when a specific data pattern is matched.

It’s not clear, however, when the trigger fires exactly. I can think of 4 options:

  1. On the last data bit sample point (middle of the last data bit?)
  2. On the last data bit end
  3. On the stop bit sample point (middle of the stop bit?)
  4. On the stop bit end

Could you please clarify?

From the Husky Triggers notebook:
“The trigger fires after the last pattern byte is received”

where “received” means “fully received”, stop bits and all. There’s also a few clock cycles latency after that.
