// ##################################################################################
// We must use hardware SPI, a minimum of 3 GPIO pins is needed.
// Typical setup for ESP8266 NodeMCU ESP-12 is :
//
// Display SDO/MISO to NodeMCU pin D6 (or leave disconnected if not reading TFT)
// Display LED to NodeMCU pin VIN (or 5V, see below)
// Display SCK to NodeMCU pin D5
// Display SDI/MOSI to NodeMCU pin D7
// Display DC (RS/AO)to NodeMCU pin D3
// Display RESET to NodeMCU pin D4 (or RST, see below)
// Display CS to NodeMCU pin D8 (or GND, see below)
// Display GND to NodeMCU pin GND (0V)
// Display VCC to NodeMCU 5V or 3.3V
//
// The TFT RESET pin can be connected to the NodeMCU RST pin or 3.3V to free up a control pin
//
// The DC (Data Command) pin may be labeled AO or RS (Register Select)
//
// With some displays such as the ILI9341 the TFT CS pin can be connected to GND if no more
// SPI devices (e.g. an SD Card) are connected, in this case comment out the #define TFT_CS
// line below so it is NOT defined. Other displays such at the ST7735 require the TFT CS pin
// to be toggled during setup, so in these cases the TFT_CS line must be defined and connected.
//
// The NodeMCU D0 pin can be used for RST
//
// See Section 2. below if DC or CS is connected to D0
//
// Note: only some versions of the NodeMCU provide the USB 5V on the VIN pin
// If 5V is not available at a pin you can use 3.3V but backlight brightness
// will be lower.

// ###### FOR ESP8266 OVERLAP MODE EDIT THE PIN NUMBERS IN THE FOLLOWING LINES ######
// Overlap mode shares the ESP8266 FLASH SPI bus with the TFT so has a performance impact

// Section 1. Define the pins that are used to interface with the display here
//
// ##################################################################################
// We must use hardware SPI, a minimum of 3 GPIO pins is needed.
// Typical setup for ESP8266 NodeMCU ESP-12 is :
//
// Display SDO/MISO to NodeMCU pin D6 (or leave disconnected if not reading TFT)
// Display LED to NodeMCU pin VIN (or 5V, see below)
// Display SCK to NodeMCU pin D5
// Display SDI/MOSI to NodeMCU pin D7
// Display DC (RS/AO)to NodeMCU pin D3
// Display RESET to NodeMCU pin D4 (or RST, see below)
// Display CS to NodeMCU pin D8 (or GND, see below)
// Display GND to NodeMCU pin GND (0V)
// Display VCC to NodeMCU 5V or 3.3V
//
// The TFT RESET pin can be connected to the NodeMCU RST pin or 3.3V to free up a control pin
//
// The DC (Data Command) pin may be labeled AO or RS (Register Select)
//
// With some displays such as the ILI9341 the TFT CS pin can be connected to GND if no more
// SPI devices (e.g. an SD Card) are connected, in this case comment out the #define TFT_CS
// line below so it is NOT defined. Other displays such at the ST7735 require the TFT CS pin
// to be toggled during setup, so in these cases the TFT_CS line must be defined and connected.
//
// The NodeMCU D0 pin can be used for RST
//
// See Section 2. below if DC or CS is connected to D0
//
// Note: only some versions of the NodeMCU provide the USB 5V on the VIN pin
// If 5V is not available at a pin you can use 3.3V but backlight brightness
// will be lower.
// ###### EDIT THE PIN NUMBERS IN THE LINES FOLLOWING TO SUIT YOUR ESP8266 SETUP ######
// For NodeMCU - use pin numbers in the form PIN_Dx where Dx is the NodeMCU pin designation
//#define TFT_CS PIN_D8 // Chip select control pin D8
//#define TFT_DC PIN_D3 // Data Command control pin
//#define TFT_RST PIN_D4 // Reset pin (could connect to NodeMCU RST, see next line)
//#define TFT_RST -1 // Set TFT_RST to -1 if the display RESET is connected to NodeMCU RST or 3.3V
//#define TOUCH_CS PIN_D1 // Chip select pin (T_CS) of touch screen
//#define TFT_WR PIN_D2 // Write strobe for modified Raspberry Pi TFT only
// ###### FOR ESP8266 OVERLAP MODE EDIT THE PIN NUMBERS IN THE FOLLOWING LINES ######
// Overlap mode shares the ESP8266 FLASH SPI bus with the TFT so has a performance impact
// but saves pins for other functions.
// Use NodeMCU SD0=MISO, SD1=MOSI, CLK=SCLK to connect to TFT in overlap mode
// In ESP8266 overlap mode the TFT chip select MUST connect to pin D3
//#define TFT_CS PIN_D3
//#define TFT_DC PIN_D5 // Data Command control pin
//#define TFT_RST PIN_D4 // Reset pin (could connect to NodeMCU RST, see next line)
//#define TFT_RST -1 // Set TFT_RST to -1 if the display RESET is connected to NodeMCU RST or 3.3V
// In ESP8266 overlap mode the following must be defined
//#define TFT_SPI_OVERLAP
// ###### EDIT THE PIN NUMBERS IN THE LINES FOLLOWING TO SUIT YOUR ESP32 SETUP ######
// For ESP32 Dev board (only tested with ILI9341 display)
// The hardware SPI can be mapped to any pins
#define TFT_MISO 19
#define TFT_MOSI 23
#define TFT_SCLK 18
#define TFT_CS 15 // Chip select control pin
#define TFT_DC 2 // Data Command control pin
#define TFT_RST 4 // Reset pin (could connect to RST pin)
//#define TFT_RST -1 // Set TFT_RST to -1 if display RESET is connected to ESP32 board RST
//#define TOUCH_CS 21 // Chip select pin (T_CS) of touch screen
//#define TFT_WR 22 // Write strobe for modified Raspberry Pi TFT only
// For the M5Stack module use these #define lines
//#define TFT_MISO 19
//#define TFT_MOSI 23
//#define TFT_SCLK 18
//#define TFT_CS 14 // Chip select control pin
//#define TFT_DC 27 // Data Command control pin
//#define TFT_RST 33 // Reset pin (could connect to Arduino RESET pin)

//
// Section 2. Define the way the DC and/or CS lines are driven (ESP8266 only)
//
// ##################################################################################
// Normally the library uses direct register access for the DC and CS lines for speed
// If D0 (GPIO16) is used for CS or DC then a different slower method must be used
// Uncomment one line if D0 is used for DC or CS
// DC on D0 = 6% performance penalty at 40MHz SPI running graphics test
// CS on D0 = 2% performance penalty at 40MHz SPI running graphics test
// #define D0_USED_FOR_DC
// #define D0_USED_FOR_CS

//
// ##################################################################################
// Comment out the #defines below with // to stop that font being loaded
// The ESP8366 and ESP32 have plenty of memory so commenting out fonts is not
// normally necessary. If all fonts are loaded the extra FLASH space required is
// about 17Kbytes. To save FLASH space only enable the fonts you need!
#define LOAD_GLCD // Font 1. Original Adafruit 8 pixel font needs ~1820 bytes in FLASH
#define LOAD_FONT2 // Font 2. Small 16 pixel high font, needs ~3534 bytes in FLASH, 96 characters

#define LOAD_FONT7 // Font 7. 7 segment 48 pixel font, needs ~2438 bytes in FLASH, only characters 1234567890:.
#define LOAD_FONT8 // Font 8. Large 75 pixel font needs ~3256 bytes in FLASH, only characters 1234567890:-.
//#define LOAD_FONT8N // Font 8. Alternative to Font 8 above, slightly narrower, so 3 digits fit a 160 pixel TFT
#define LOAD_GFXFF // FreeFonts. Include access to the 48 Adafruit_GFX free fonts FF1 to FF48 and custom fonts
// Comment out the #define below to stop the SPIFFS filing system and smooth font code being loaded
