So this is a bit of an odd issue from my perspective. The code I'm using worked previously in interfacing with the PLX DAQ excel spreadsheet, but now when I attempt to connect the spreadsheet to the Arduino, I get the error message, "StampDAQ could not connect. Please check port settings." So naturally I've checked and rechecked the port settings. The Arduino is connected to COM 1, and the spreadsheet is set up to read it. Strangely enough, if I try a second time immediately, it connects, and indicates that it is receiving data, but does not log the data in any way. Ordinarily, I would expect the spreadsheet to reformat as it had done in the past, by renaming columns and the like, but nothing happens.
Does anyone have any experience with this sort of thing, or can you perhaps point me in a particular direction? Any sort of help is appreciated, as this sort of error is completely new to me.
