Limitations with Data Streamer

Occasional Contributor

I am trying to use Data Streamer to do simple data exchange with an MCU via a serial port.

I would like to send a csv packet to the MCU and get the csv it will reply. 


I made a basic Excel application with



  • When "Start Data" is off, the content of "Data Out" is sent when there is a change but "Data In" is not updated and
  • When "Start Data" is on, "Data In" is updated but "Data Out" is repeated on every update.


Is there a way to have "Data In" updated and "Data Out" is sent only when there is a change?

A partial solution I found is to turn off the automatic calculation.
