we are working with multiple instances patch in VVVV and one of these instances is communicating via Arduino with the RS232 node.
We are experiencing some strange behaviour here:
- When the RS232 instance of V4 is in foreground everything works fine: Arduino loop is working well, data from it are correctly received by V4 and correctly dispatched to other V4 instances.
- But, when RS232 instance is in background the connection with Arduino is lost (last output from RS232 node is zero!). As a consequence Arduino loop starts behaving erratically and ather V4 instances are not receiving data anymore.
Trying to solve the issue we tried the following:
- Bring the RS232 instance to top using the “ShowWindow” node and forwarding data from Arduino the other instances using the “UDP” node --> This doesn’t work! Connection stays open (even if with a little flicker) but data are not forwarded!
- Bring the RS232 instance to top using the “ShowWindow” node and forwarding data from Arduino the other instances using the “Shared Memory” node --> This works for us: connection stays open and data are correctly forwarded.
Any ideas, suggestions?
Thank you very much for your support
