Attempting to get SPI running on ESP8266 D1 mini along with RFM69/95 for USA - Git source link desired

I found these forum references:

http://forum.espruino.com/conversations/285936/#12951616
'There are definitely pins you can't touch because they're used for the flash chip (the 6 pins at bottom of the esp12E modules)'

http://forum.espruino.com/conversations/307305/
'These are used by the internal flash chip - you will have issues if you use these pins!'

and they both agree with L409-L413 in the jshardware.c assert source note.

So it appears for this particular board, that the prefix 'NodeMCU' must be used for the pin assignments.

More for tomorrow, take a fresh look at all the 'D' references and compare with the pin images.
