Data Variable Toolkit
Aniket Gadekar posted a topic in LabVIEW GeneralHello Everyone, I have created this feature to create named variables of any data type in memory and access its value from any part of data code which is under same scope using its name. This variables stores instantaneous value. Best use case of this toolkit is acquire data set variable values & read from any loop. Do not use for Read-Modify-Write Once variables are created in memory, you can be grouped them and access its values using names. You can create variable for any data datatype & access its value using its Name. I have tested this toolkit for memory & performance, which is much faster than CVT & Tag Bus Library Please check and let me know your suggestions. use LabVIEW 15 sp1 BR, Aniket Gadekar, firstname.lastname@example.org DataVariableToolkit.zip
phurley posted a topic in Application Design & ArchitectureI am mentoring an FRC team and we were discussing a design where we have a couple channels of information, some of which is very high frequency and losing data is not too important, so we are using a notifier. We also have a different channel of data which is much lower frequency, but losing any would be an big problem and we are using a queue. Now the tricky part we would like to be able to wait on data from either source (preferably not busy wait). I have come up with a a couple possibilities: Busy wait on both, looping between checking both sources and a 0 delay in the loop to prevent starving the rest of the code. Tweak the queue based send to also push data to the high volume notifier, when I get a read on the notifier also check the queue and process it. User events? Not sure, but this looks right; however, note that the notifications/queue messages are generated in one subVI (which is called by external framework code) and being sent to another subVI which has a number of long running control loops in it. I was hoping for something a little more elegant, that I have overlooked. Any pointers? Thanks from an old C programmer still trying to get comfortable in labview.
