I have a system based on arduino uno sending data to excell via plx-daq. The problem is occured whilere connecting plx-daq, new data rewrites to already filled cells. How to make data write to empty cells when pxl-daq is reconnected (or pc restart)?
There is a directive for the row, where data shall be put, as far as I have seen.
So if you can keep track on the controller side, you can direct the next position.
