## hextoppm.c
/*
   hex2ppm.c -- this is a hack.
   (Arduino ILI9341_due library ILIScreenshotViewer is Windows only)

   Just copy the hex line from Serial console to eg. "scr.hex" file.
   Then "hex2ppm src.hex > src.ppm" (followed by ppmtojpeg if needed).

   Sample "tft.screenshotToConsole();" output in serial console window:
   ==== PIXEL DATA START ====
   0000000002 ... 1D4D0D4013F000015B8
