2.1 TFT屏幕的配置文件
// USER DEFINED SETTINGS

// Section 2. Define the pins that are used to interface with the display here
//
// ##################################################################################
// 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
// driven with a PWM signal or turned OFF/ON then this must be handled by the user
// sketch. e.g. with digitalWrite(TFT_BL, LOW);
// #define TFT_BL 32 // 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 ######
// // 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 TFT_BL PIN_D1 // LED back-light (only for ST7789 with backlight control pin)
//#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!
// Note: Only one SPI device can share the FLASH SPI lines, so a SPI touch controller
// cannot be connected as well to the same SPI signals.
// 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_RST -1 // Set TFT_RST to -1 if the display RESET is connected to NodeMCU RST or 3.3V

// ###### 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

//#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

// ##################################################################################
// For RP2040 processor and SPI displays, uncomment the following line to use the PIO interface.
//#define RP2040_PIO_SPI // Leave commented out to use standard RP2040 SPI port interface
// For RP2040 processor and 8 or 16 bit parallel displays:
// The parallel interface write cycle period is derived from a division of the CPU clock
// speed so scales with the processor clock. This means that the divider ratio may need
// to be increased when overclocking. I may also need to be adjusted dependant on the
// display controller type (ILI94341, HX8357C etc). If RP2040_PIO_CLK_DIV is not defined
// the library will set default values which may not suit your display.
// The display controller data sheet will specify the minimum write cycle period. The
// controllers often work reliably for shorter periods, however if the period is too short
// the display may not initialise or graphics will become corrupted.
// PIO write cycle frequency = (CPU clock/(4 * RP2040_PIO_CLK_DIV))
//#define RP2040_PIO_CLK_DIV 1 // 32ns write cycle at 125MHz CPU clock
//#define RP2040_PIO_CLK_DIV 2 // 64ns write cycle at 125MHz CPU clock
//#define RP2040_PIO_CLK_DIV 3 // 96ns write cycle at 125MHz CPU clock
// For the RP2040 processor define the SPI port channel used (default 0 if undefined)
//#define TFT_SPI_PORT 1 // Set to 0 if SPI0 pins are used, or 1 if spi1 pins used
// For the STM32 processor define the SPI port channel used (default 1 if undefined)
//#define TFT_SPI_PORT 2 // Set to 1 for SPI port 1, or 2 for SPI port 2
// Define the SPI clock frequency, this affects the graphics rendering speed. Too
// fast and the TFT driver will not keep up and display corruption appears.
// 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.
// #define SPI_FREQUENCY 1000000
// #define SPI_FREQUENCY 5000000

// #define SPI_FREQUENCY 80000000
// Optional reduced SPI frequency for reading TFT
#define SPI_READ_FREQUENCY 20000000
// The XPT2046 requires a lower SPI clock rate of 2.5MHz so we define that here:
#define SPI_TOUCH_FREQUENCY 2500000
// 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.
// Transactions are automatically enabled by the library for an ESP32 (to use HAL mutex)
// so changing it here has no effect
// #define SUPPORT_TRANSACTIONS
