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 https://support.microsoft.com/en-us/office/what-is-data-streamer-1d52ffce-261c-4d7b-8017-89e8ee2b806....
- 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?
