// If a backlight control signal is available then define the TFT_BL pin in Section 2
// below. The backlight will be turned ON when tft.begin() is called, but the library
// needs to know if the LEDs are ON with the pin HIGH or LOW. If the LEDs are to be

// sketch. e.g. with digitalWrite(TFT_BL, LOW);
//#define TFT_BL 27 // LED back-light control pin
//#define TFT_BACKLIGHT_ON HIGH // Level to turn ON back-light (HIGH or LOW)
// 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 labelled 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
//
//
// 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 ######

//#define TOUCH_CS PIN_D2 // 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. It is best not to connect MISO as some displays
// do not tristate that line when chip select is high!
// On NodeMCU 1.0 SD0=MISO, SD1=MOSI, CLK=SCLK to connect to TFT in overlap mode
// On NodeMCU V3 S0 =MISO, S1 =MOSI, S2 =SCLK
// In ESP8266 overlap mode the following must be defined
//#define TFT_SPI_OVERLAP
// 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_BL 32 // LED back-light (required for M5Stack)
// ###### EDIT THE PINs BELOW TO SUIT YOUR ESP32 PARALLEL TFT SETUP ######
// The library supports 8 bit parallel TFTs with the ESP32, the pin
// selection below is compatible with ESP32 boards in UNO format.
// Wemos D32 boards need to be modified, see diagram in Tools folder.
// Only ILI9481 and ILI9341 based displays have been tested!
// Parallel bus is only supported for the STM32 and ESP32
// Example below is for ESP32 Parallel interface with UNO displays
// Tell the library to use 8 bit parallel mode (otherwise SPI is assumed)
//#define TFT_PARALLEL_8_BIT
// The ESP32 and TFT the pins used for testing are:
//#define TFT_CS 33 // Chip select control pin (library pulls permanently low
//#define TFT_DC 15 // Data Command control pin - must use a pin in the range 0-31
//#define TFT_RST 32 // Reset pin, toggles on startup
//#define TFT_WR 4 // Write strobe control pin - must use a pin in the range 0-31
//#define TFT_RD 2 // Read strobe control pin
//#define TFT_D0 12 // Must use pins in the range 0-31 for the data bus
//#define TFT_D1 13 // so a single register write sets/clears all bits.
//#define TFT_D2 26 // Pins can be randomly assigned, this does not affect
//#define TFT_D3 25 // TFT screen update performance.
//#define TFT_D4 17
//#define TFT_D5 16
//#define TFT_D6 27
//#define TFT_D7 14

//#define TFT_CS D5 // Chip select control pin to TFT CS
//#define TFT_DC D6 // Data Command control pin to TFT DC (may be labelled RS = Register Select)
//#define TFT_RST D7 // Reset pin to TFT RST (or RESET)
// OR alternatively, we can use STM32 port reference names PXnn
//#define TFT_CS PE11 // Nucleo-F767ZI equivalent of D5
//#define TFT_DC PE9 // Nucleo-F767ZI equivalent of D6
//#define TFT_RST PF13 // Nucleo-F767ZI equivalent of D7
//#define TFT_RST -1 // Set TFT_RST to -1 if the display RESET is connected to processor reset
// Use an Arduino pin for initial testing as connecting to processor reset
// may not work (pulse too short at power up?)

// Section 3. Define the fonts that are to be used here
//
// ##################################################################################
// 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_FONT4 // Font 4. Medium 26 pixel high font, needs ~5848 bytes in FLASH, 96 characters
#define LOAD_FONT6 // Font 6. Large 48 pixel font, needs ~2666 bytes in FLASH, only characters 1234567890:-.apm
#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
// this will save ~20kbytes of FLASH
#define SMOOTH_FONT

// Section 4. Other options
//
// ##################################################################################
// Define the SPI clock frequency, this affects the graphics rendering speed. Too

// With an ILI9341 display 40MHz works OK, 80MHz sometimes fails
// With a ST7735 display more than 27MHz may not work (spurious pixels and lines)
// With an ILI9163 display 27 MHz works OK.

// The ESP32 has 2 free SPI ports i.e. VSPI and HSPI, the VSPI is the default.
// If the VSPI port is in use and pins are not accessible (e.g. TTGO T-Beam)
// then uncomment the following line:
//#define USE_HSPI_PORT
// Comment out the following #define if "SPI Transactions" do not need to be
// supported. When commented out the code size will be smaller and sketches will
// run slightly faster, so leave it commented out unless you need it!
// Transaction support is needed to work with SD library but not needed with TFT_SdFat
// Transaction support is required if other SPI devices are connected.
