// The User_Setup header that will be called up is defined in User_Setup_Select.h

// Set driver type, fonts to be loaded, pins used and SPI control method etc
//
// If this file is editted correctly then all the library example sketches should
// run without the need to make any more changes for a particular hardware setup!
// IMPORTANT
// This particular setup uses the SPI overlap capabiltiy of the ESP8266, this allows
// the FLASH SPI pins to be re-used with the TFT, saving pins for other functions.

// Only define one driver, the other ones must be commented out
//#define ILI9341_DRIVER

// For ST7735 and ILI9163 ONLY, define the pixel width and height in portrait orientation
#define TFT_WIDTH 128

//#define TFT_HEIGHT 128
// For ST7735 ONLY, define the type of display, originally this was based on the

// out the different options below if the screen does not display graphics correctly,
// e.g. colours wrong, mirror images, or tray pixels at the edges.
// Comment out ALL BUT ONE of these options for a ST7735 display driver, save this

// ##################################################################################
// We must use hardware SPI, a minimum of 3 GPIO pins is needed.
// Typical setup for NodeMCU ESP-12 with SPI overlap is :
//
// Display SDO/MISO to NodeMCU SD0 (or leave disconnected if not reading TFT)
// Display LED to NodeMCU pin VIN (or 5V, see below)
// Display SCK to NodeMCU pin CLK
// Display SDI/MOSI to NodeMCU pin SD1
// Display DC (or AO)to NodeMCU pin D5 / GPIO 14
// Display RESET to NodeMCU pin D4 / GPIO 2 (or RST, see below)
// Display CS to NodeMCU pin D3 / GPIO 0
// Display GND to NodeMCU pin GND (0V)
// Display VCC to NodeMCU 5V (Vin) 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 NodeMCU D0 pin can be used for RST
//
// See Section 2. below if DC 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.

// Section 2. Define the way the DC and/or CS lines are driven
//
// ##################################################################################
// 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

// 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 had 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 the SPI clock frequency
// With an ILI9341 display 40MHz works OK, 80MHz sometimes fails
// With a ST7735 display more than 27MHz may not work (spurious pixels and lines)
// #define SPI_FREQUENCY 1000000
// #define SPI_FREQUENCY 5000000
// #define SPI_FREQUENCY 10000000
// #define SPI_FREQUENCY 20000000
#define SPI_FREQUENCY 27000000 // Maximum for my ST7735. It is actually 26.67MHz = 80/3
// #define SPI_FREQUENCY 40000000 // Maximum to use SPIFFS
// #define SPI_FREQUENCY 80000000
// Comment out the following #define if "SPI Transactions" do not need to be
// supported. Tranaction support is required if other SPI devices are connected.
// 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
// #define SUPPORT_TRANSACTIONS
// If this next #define is not commented out then the SPI pins used by the program FLASH
// can be shared with the TFT, this frees up the HSPI SCK, MOSI and MISO pins.
// The TFT must be connected as follows for this to work:
// TFT Chip Select to GPIO0 (pin D3 on a NodeMCU)
// TFT MOSI/SDA to GPIO8/SDD1 (pin SD1 on a NodeMCU)
// TFT MISO to GPIO7/SDD0 (pin SD0 on a NodeMCU) - does not need to be connected
// TFT SCK to GPIO6/SDCLK (pin CLK on a NodeMCU)
