Supportanfrage

Ich habe nochmal feedback zur Device toolb0x 3.5.0 und dem CAN signal provider:

Still does not work well. Please consider the same issue also for CANFD, Flexray, SomeIP ...

The CAN Signal Provider has a heavy performance penalty in synchronous processing.

Without CAN Signal Provider I have a rate of 500 Samples/seconds from a testing CAN device source (samples are created in a thread). After adding the CAN Signal Provider to the system, the rate drops to below 100 Samples/seconds. This indicates that the CAN Signal Provider adds a lot of synchronous processing to the trigger on the CAN stream. So this would render it unusable in a live situation. A more asynchronous method needs to be used for providing the signals. Also reduced performance requirements would probably be appreciated by others, since some users work with several CAN streams in parallel.
Is it possible to take the Media Description Service's signal providing functionality as a template for implementation? Since this seems to work well.

Workaround I used:
Do not use the CAN signal provider. Instead connect the CAN output pin of the CAN device source to a CAN Substream Decoder (and connect its output pin to a Sample Stream). Then use the Media Description Service's signal providing functionality.

Since I also usually show the CAN signal provider to customers as one of its important features.

For measuring the samples the Sample Trace View UI service was used.
