// Overlap mode shares the ESP8266 FLASH SPI bus with the TFT so has a performance impact
// but saves pins for other functions. It is best not to connect MISO as some displays
// do not tristate that line wjen chip select is high!
// do not tristate that line when chip select is high!
// Note: Only one SPI device can share the FLASH SPI lines, so a SPI touch controller
// cannot be connected as well to the same SPI signals.
// On NodeMCU 1.0 SD0=MISO, SD1=MOSI, CLK=SCLK to connect to TFT in overlap mode
// On NodeMCU V3 S0 =MISO, S1 =MOSI, S2 =SCLK
// In ESP8266 overlap mode the following must be defined
