I have been able to compile and upload the "Blink / Hello World" test using pin 2 as and output to drive the LED. When I selected pin 15, the serial monitor produced pages of "stuff" without the "Hello world" being displayed.
According to the picture I have for this IC and board, pin 15 should be GPIO15.
Since this is my second attempt to understand the development board, I am probably doing something wrong. Please excuse an old man (83) for asking basic questions. Can some one point me in the correct direction?
