ESP32-TFT-Library-ILI9486

A library for 3.5 inch RPi LCD (A) 320x480 display from Waveshare, for LCD (B) comment line 61 and uncomment line 62 in tft.cpp
Display

Create new fonts with MikroElektronika GLCD Font Creator and insert the new font in fonts.h
You can also display bitmaps, touchpadcontroller XPT2046 is included
