// **** 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!!!!
