***********************
Cpu boards supported
***********************
TFT_eSPI library is optimised for the Raspberry Pi Pico (RP2040), STM32, ESP8266 and ESP32.


***********************
TFT chips supported :
***********************

TFT_Display : 160 x 128 / 320 x 240 / 480 x 320
TFT_WIDTH : 80 < 240
TFT_HEIGHT : 160 < 320


***********************
TFT_eSPI configuration :
***********************
configuration is done in file <User_Setup.h> and in a file <User_Setup_Select.h> in TFT_eSPI library directory
(in directory TFT_eSPI\User-Setups\ several User-Setups are available depending of processor board and TFT chip configuration.)

1)in User_Setup_Select.h
User_Setup file is selected and content is depending of your configuration.(CPU and TFT boards)
only one lines must be define
2)in User_Setup.h :
Section 1. Define the right driver file and any options for your TFT board

Section 2. Define the CPU board pins that are used to interface with the display
define flag to use touch screen
#define TOUCH_CS PIN_xx // Chip select pin (T_CS) of touch screen
Section 3. Define the fonts by default that can to be used
define fonts used by default 1<8
#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 flag to use FreeFonts
#define LOAD_GFXFF // FreeFonts. Include access to the 48 Adafruit_GFX free fonts and custom fonts
define flag to use smooth fonts
#define SMOOTH_FONT
Section 4. Other options

***********************
this wrapper can handle:
***********************
TFT_eSPI.h
extension TFT_eSPI_Touch depending of flag #ifdef TOUCH_CS
extension TFT_eSPI_SmoothFont depending of flag #ifdef LOAD_GFXFF
extension TFT_eSprite.h
extension TFT_eSPI_Button.h
extension PNGdec.h (after library and wrapper installation)
extension TFT_eWidget.h (after library and wrapper installation)

not working in B4R
JPEGDecoder.h
OpenFontRender.h

**************************
GFX Fonts management:
**************************
GFX fonts can be managed in 2 ways:
-------------------------------
1) in default configuration 8 fonts are available with parameter font = 1<8

2) after with <#ifdef LOAD_GFXFF> added, FreeFonts/GFX/custom Fonts can be used. it give access to the 48 Adafruit_GFX free fonts and custom fonts.
Short naming of font FF1 to FF48 from <Free_Fonts.h> cannot be used with B4R but after a definition in inline C, each freefonts can be used by an index number 0 < xxx

example is depending of GFXFF flag :
void setFreeFont(byte GFXid); case GFXFF flag on
void setTextFont(byte font); case GFXFF flag on
void setFreeFont1(byte font); case GFXFF flag off
void setTextFont1(byte font); case GFXFF flag off

in B4R, GFX/FreeFonts declarations are added in B4R script, in inline C part to be selected with a byte
example for 8 fonts:
B4X:
#if C
   const GFXfont * B4R::B4RTFT_eSPI::GFXfonts[7]= {
       &FreeMono9pt7b,                 // => setFreeFont(00)
       &FreeSans9pt7b,                 // => setFreeFont(01)
       &FreeSerif9pt7b,                // => setFreeFont(02)
       &FreeMonoBold9pt7b,             // => setFreeFont(03)
       &FreeMonoBoldOblique9pt7b,      // => setFreeFont(04)
       &FreeMonoOblique9pt7b,          // => setFreeFont(05)
       &FreeSansBold9pt7b              // => setFreeFont(06)
   };
#End If

************************
VLW fonts management:
************************
Anti-aliased fonts in VLW format can be used after loading in 4 ways:
- VLW fonts can be loaded by SPIFFS on esp8266 and esp32
uint8_t loadFontLittleFS(B4RString* fontName);
- VLW fonts can be loaded by LittleFS
void loadFontFS(B4RString* fontName);
- VLW fonts can be loaded from SD card on esp32
uint8_t loadFontSD(B4RString* fontName);
- 8 VLW fonts can be added in flash in h files, in vlw format converted to C arrays. (h file are added at project in inline C)
void loadFontH(byte VLWid);
VLW in h files can be loaded after definition in inline C
8 VLW fonts can be added by <#define VLW0 font0> to <#define VLW7 font7>:
h files must be in directory with rTFT_eSPI or TFT_eSPI

example of vlw fonts in h file added in inline C:
B4X:
#if C
   #include "NotoSansBold15.h"
   #include "NotoSansBold36.h"
      #undef VLW0                                 // with VLW0 to VLW7
      #define VLW0 NotoSansBold15            // => loadFontH(00)
      #undef VLW1
      #define VLW1 NotoSansBold36            // => loadFontH(01)
#end if

************************
PNG files management: case png in a h file
************************
library from: https://github.com/bitbank2/PNGdec
PNG can be loaded in 3 ways
- png can be loaded from memory
int16_t openRAM(ArrayByte* pData, SubVoid_DblIntInt pngDrawSub);
- png can be loaded from a file LittleFS (esp8266 / esp32)
int16_t open(B4RString* szFilename, SubVoid_DblIntInt pngDrawSub);
in this case, png must be in LittleFS partition
- png can ba loaded from an array in h file
int16_t openFLASH(byte PNGid, SubVoid_DblIntInt pngDrawSub);
in this case, png files must be in directory with rPNGdec or PNGdec
h files must be added by #include
in inline C, PNG names are included in an array , PNG size are also included in an array
acces is done by a PNG number
In B4R program, PNG arrays can be loaded with PNGdec from this array with number 0 < 8

example of PNG in h file added in inline C:
B4X:
#if C
   #include "SpongeBob.h"
      const uint8_t* B4R::B4RPNG::PNGfiles[2]= {
         bob,                 // => openFLASH(00, sizeof(bob),....
         bob1
      };
      const uint32_t B4R::B4RPNG::PNGsize[2]= {
         sizeof(bob)                 // => openFLASH(00, sizeof(bob),....
         sizeof(bob1)                // => openFLASH(01, sizeof(bob1,....
      };
#Enf If

by 24/02/09, a few modifications added on in TFT_eSPI, library TFT_eWidget added

TFT_eSPI is one of the most powerful TFT driving libs. I used it in one of my recent projects to drive ST7735 1.8" TFT, it works very well and very stable, unfortunately, the wrapper was not available at that time, so I had to use inline C calls, will give a try with the new B4R lib.

************************
Gestion des fichiers PNG : cas png dans un fichier h
************************
Bibliothèque de : https://github.com/bitbank2/PNGdec
Le format PNG peut être chargé de 3 façons
- Le PNG peut être chargé à partir de la mémoire
int16_t openRAM(ArrayByte* pData, SubVoid_DblIntInt pngDrawSub) ;
- png peut être chargé à partir d’un fichier LittleFS (esp8266 / esp32)
int16_t open(B4RString* szFilename, SubVoid_DblIntInt pngDrawSub) ;
dans ce cas, png doit être dans la partition LittleFS
- png peut être chargé à partir d’un tableau dans le fichier h
int16_t openFLASH(octet PNGid, SubVoid_DblIntInt pngDrawSub) ;
dans ce cas, les fichiers png doivent se trouver dans le répertoire avec rPNGdec ou PNGdec
h doivent être ajoutés par #include
en C en ligne, les noms PNG sont inclus dans un tableau, la taille PNG est également incluse dans un tableau
l’accès se fait par un numéro PNG
Dans le programme B4R, les tableaux PNG peuvent être chargés avec PNGdec à partir de ce tableau avec le numéro 0 < 8

exemple de fichier PNG in h ajouté en C en ligne :
B4X:
#if C
#include « Bob l’éponge »
const uint8_t* B4R ::B4RPNG ::P NGfiles[2]= {
         bob,                 // => openFLASH(00, sizeof(bob),....
         bob1
      };
const uint32_t B4R ::B4RPNG ::P NGsize[2]= {
         sizeof(bob)                 // => openFLASH(00, sizeof(bob),....
         sizeof(bob1)                // => openFLASH(01, sizeof(bob1,....
      };
#Enf Si

Le 24/02/09, quelques modifications ont été ajoutées dans TFT_eSPI, la bibliothèque TFT_eWidget ajoutée

Yes, of course, there are all the libraries provided by electronic label manufacturers but which I can currently only use if I use ARDUINO IDE
See the forum here

The fonts exist (AdafruitGFX posted online by EREL on 01/16/2017) but a specific library of the EPD2 type is missing, I tried in vain to use LCDWIKI_SPI but it blocks
