Hi, I am trying to migrate from classical serial polling communications to serial queue with "event handler" for the buttons pressed by the user. I have placed four while loops, one for the event handler, a second one for serial reading, a third one for serial writing (depending on what button was pressed) and the last one for processing what was read from the serial reading while loop, via a queue.
My attached device reads the signals from 8 sensor ( 4 temperature and another 4 temperature plus humidity in the same sensor ) and send them via serial to Lavbiew.
First of all, only once just after running the LV program, I must turn on my attached device with an ON command plus a carriage return after that the device will respond with the number of sensors plugged to it, disabling the corresponding buttons in the front panel. Then labview must wait until I pressed Acquire Button (event handler) and send a CF command plus what sensors to acquire plus a carriage return, then the device will respond continuously to labview with the sensor readings until I press the stop button (event handler), there is also another button to exit the program, also with event handler.
I am having problems using the event handler and the queues because I am new using these structures, I have looked at the LV examples but there is nothing concrete on using serial with event handler and queue.
Take a look at my VI and you will soon notice what kind of problems I am having, any suggestions will welcome.
Thank's in advance.
Regards.
