// **** NOTE: There are two very lame libaries conspiring to make life difficult ****
// A/ The ESP32 SPI.cpp library instatiates an instance of SPI, using the VSPI port (and pins)
// B/ The Adfruit_SH1106 library has hard coded "SPI" as the SPI port instance
//
// As an ESP32 has a pin multiplexer, this is very bad form.
// The design uses the defacto HSPI pins (and port),
// You **MUST comment out the SPIClass SPI(VSPI);** at the end of the ESP32 SPI library
// then we declare "SPI" here, which will use HSPI!!!!
