@brief An optional adjunct to Adafruit_EPD that reads bitmap or RGB
|
|
BMP images (maybe others in the future) from a flash filesystem
|
|
(SD card or SPI/QSPI flash). It's purposefully been made an
|
|
entirely separate class (rather than part of SPITFT or GFX
|
|
classes) so that Arduino code that uses GFX or SPITFT *without*
|
|
image loading does not need to incur the RAM overhead and
|
|
additional dependencies of the Adafruit_SPIFlash library by
|
|
its mere inclusion. The syntaxes can therefore be a bit
|
|
bizarre (passing display object as an argument), see examples
|
|
for use.
