/**
|
|
* An adapter class that allows using the TFT_eSPI library as if it was an OLEDDisplay implementation.
|
|
*
|
|
* Remaining TODO:
|
|
* optimize display() to only draw changed pixels (see other OLED subclasses for examples)
|
|
* implement displayOn/displayOff to turn off the TFT device (and backlight)
|
|
* Use the fast NRF52 SPI API rather than the slow standard arduino version
|
|
*
|
|
* turn radio back on - currently with both on spi bus is fucked? or are we leaving chip select asserted?
