event structures and poling at the same time

[bluefocs]

Hello,

I am writing a Vi which gets some data from a serial port analyses it then displays it. I am using a state machine to achieve this, so it poles for any data on the serial port in a "Wait for data" state

I have two dials on my front panel, and when they change value I'd like to jump to particular state. 

I wanted to use an event structure for this, but it doesn't seem to behave as I'd hoped (like an interupt on a microcontroller or an event in C#) it waits at the beginning until one of the events occurs then continues.

 Will I need to re-do how I detect data from my serial port and buttons on the front panel?

And  

Is it possible the event structure to check for data on a serial port?

I attached a screenshot to give you an idea what I am doing.

You could use a producer/consumer event based for the UI control. The consumer should be extended to a queued statemachine working with the serial port.

Another option would be a second (polling) producer which enqueues to the same queue in order to supply data to the consumer. The consumer would have to evaluate and react on the data/commands which are generated by both producer.

hope this helps,

Norbert

You can create an user event and fire that when from the polling cycle, then handle the data inside the event structure.
