Polling vs. event driven


#1

I want to get indiciation of events from the FPGA, but I don’t necessarily want to have a polling mechanism (isTriggered…).

Is there an event driven approach to the problem ? if not what is the minimum response time you have achieved. I’m concerned about CPU load vs. response time.

Thanks

Hi Amir-

Polling is the only method. The “event-driven” methods provided in FrontPanel-1 (which are not available in the new FrontPanel-3, by the way), depend on polling.

CPU load for periodic polling of the device via UpdateWireOuts, etc, is very small.
