I have to admit that I am at times far too impatient.
The sketch works but once loaded it will not write to the serial monitor. I must first reset the micro, then reset it a second time, then open up the serial monitor to see the table being printed. The first rest causes the micro to lose the com port. The second reset re-establishes the port and allows the serial monitor to be printed to.
I have 0 experience and less knowledge but hopefully what observation I just posted confirms your suspicion that you posted above.
Thank you,
Paul
