Sample of scrolling the HX8357 through hardware in portrait mode.  I wanted a way to dump Serial to this little screen, which required some sort of scrolling.  I could not find anything except the hardware manual for the chip to perform scrolling so I wrote this little class to implement a smooth scroll.  This class uses the AdaFruit HX8357 tft driver, but could probably be used with other drivers using similar hardware.





You can get the board from here:


https://www.amazon.com/gp/product/B00TIYUWNY/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1


or AdaFruit directly at:


https://www.adafruit.com/?q=hxd8357d








Class inherits from Print.


Additional methods:


  config(int rotation, int textsize);


    Calls the underlying TFT methods for rotation and text size.


  setTextSize(int textsize);


    Sets text size. Can be used between calls to change text size between output calls.


  SetTextColor(unsigned short)


    Set text color.


  SetBackgroundColor(unsigned short)


    Set text background color.


  setLinePadSize(int y);


    Sets number of pixels between each line of text. Defaults to two.








Limitations:


No word wrap.  Currently truncates anything greater than max chars per line (320 / 8 * textsize).
