// 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 21 // 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 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

// 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

there are 3 compiled firmware version
1. VaandcobOBD2_T6_2023.bin
- this is an original firmware from that work with ford T6 up with transmission 6R80, 10R80
- work very well before some libraries updated.
2. VaandcobOBD2_T5.bin
- this is a new firmware for old ford T5 vehicle with old automatic transmission
3. for firmware suffix with _nogenuine.bin are the version that skip genuine board check.
----------------------------------------
You can flash firmware with web flasher tool ->

/*========= Va&Cob OBD2 Gauge ========== /*=============================================================================
Programmed: by Ratthanin W. * Cluster Digital OBD-II ESP32 CYD (Ford Ka Endura 1.3)
Hardware: * Placa: ESP32-2432S028 con pantalla táctil TFT 2.8" (320x240)
- Hardware 2.8" TFT ESP32 LVGL https://www.youtube.com/watch?v=d2OXlVcRYrU * Comunicación: Bluetooth SPP con adaptador ELM327 v1.5
Configuration: * Esquema de partición: huge_app (3MB APP / No OTA / LittleFS)
- Partition scheme *=============================================================================*/
Minimal SPIFFS 1.9MB APP/ 190kB SPIFFS /OTA (for OTA ,must reduce code size)
Important Note:
- New device must flash "gauge_factory_init.ino" first to get it work by checking 'serialno' in pref.
or you can skip genuine checking by comment out line no. 338
- CPU temp read never work until Bluetooth or Wifi is connected
About opening logo image and goodbye image.
- you can save welcome page logo into gauge by saving file name "vaandcob.jpg" size 320x240 pixels into littleFS storage.
- you can save goodbye page image into gauge by saving file name "mypic.jpg" size 320z240 pixels into littleFS storage
* if you don't want to use it, you can comment out code line no. 320 - 322
