# 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
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
Examplecodes:
```` c++
#include "Arduino.h"
#include "ili9486.h"
// GPIOs for SPI
#define SPI_MOSI 23
#define SPI_MISO 19
#define SPI_SCK 18
// GPIOs for TFT/TP
#define TFT_CS 22
#define TFT_DC 5
#define TP_CS 13
#define TP_IRQ 12
