rsapi.dll with Excel VB, replace with arduino??

Hiddenvision:
Ok So this interacts with the software.
Just to note that rsapi seems to ignore bytes that are 0.

Terrible looking code example but it works.!
I needed to edit the macros a little to add a Delay(1500) when the comport is opened.
Remember the Arduino normally resets when the port is opened.
That reset may make it miss any SENDBYTE(X) that happen just after the port opens.

Hi H

THIS IS JUST AWESOME! :smiley:
If this code is terrible looking, that just tells me how bad I am with arduino coding. Because this looks really good to me! :smiley:

I also did the changes in the macro as you suggested, I and communication between Arduino and Excel seems to work! :slight_smile:

I can't thank you enough!
Now the testin begins :smiley:

Thanks
