## Ease of use

### Simple Declaration

```C
#include <Arduino_GFX_Library.h>
Arduino_DataBus *bus = new Arduino_HWSPI(16 /* DC */, 5 /* CS */);
Arduino_GFX *gfx = new Arduino_ILI9341(bus, 17 /* RST */);
```

### And Simple Usage

```C
gfx->begin();
gfx->fillScreen(BLACK);
gfx->setCursor(10, 10);
gfx->setTextColor(RED);
gfx->println("Hello World!");
```

## U8g2 Font Support

[U8g2](https://github.com/olikraus/u8g2.git) provided various font type and stored in compressed format. So U8g2 font gives more UI design possibilities and still can fit in the MCU limited storage space. Using U8g2 font in Arduino_GFX simply include U8g2lib.h before Arduino_GFX_Library.h:

```C
#include <U8g2lib.h>
#include <Arduino_GFX_Library.h>
```

And then setfont file to use:

```C
gfx->setCursor(10, 20);
gfx->setFont(u8g2_font_maniac_tr);
gfx->println("Hello World!");
```

U8g2 font list can be found at: <https://github.com/olikraus/u8g2/wiki/fntlistall>

### U8g2 Unicode (UTF8) Font Support

Another U8g2 font advantage is the font support Unicode glyphs. Simply enable setUTF8Print:

```C
gfx->begin();
gfx->fillScreen(BLACK);
gfx->setUTF8Print(true);
```

And then print UTF8 string as usual:

```C
gfx->setCursor(0, 16);

gfx->setFont(u8g2_font_unifont_tr);
gfx->println("Hello World!");

gfx->setFont(u8g2_font_unifont_t_polish);
gfx->println("Witaj świecie!");

gfx->setFont(u8g2_font_unifont_t_vietnamese1);
gfx->println("Chào thế giới!");

gfx->setFont(u8g2_font_unifont_t_chinese2);
gfx->println("世界你好!");

gfx->setFont(u8g2_font_unifont_t_japanese1);
gfx->println("こんにちは世界!");

gfx->setFont(u8g2_font_unifont_t_korean1);
gfx->println("안녕하세요, 세계입니다!");
```

### Why Run Fast?

* No read operation. Since not all display provide read back graphic memories API, Arduino_GFX skip all read operations. It can reduce the library size footprint and sometimes reduce the operation time.
* Tailor-made data bus classes. Arduino_GFX decouple data bus operation from display driver, it is more easy to write individual data bus class for each platform.

## Various data bus interfaces

Arduino_GFX utilizes Arduino Built-in SPI class to support 8-bit SPI for most platforms.

Most tiny displays in hobbyist electronics world support 8-bit SPI, but some require 9-bit SPI. Arduino_GFX should be the first Arduino display library that can use ESP32 SPI to support 9-bit hardware SPI. It is important to support the displays that require 9-bit SPI interface. (e.g. HX8357B, ...)

Larger displays most likely do not support standalone SPI since it is not fast enough to refresh the full screen details. Most of them support 8-bit/16-bit Parallel interface.

Some larger display require RGB + 3-bit SPI combo interface, This interface requies at most 3(9-bit SPI) + 4(CS, CD, WR, RD) + 24(RBG888) = 31 pins. Most dev board do not have enough GPIO to support this. Arduino_GFX is stick to RGB565 color, so RGB666 and RGB888 require some connection hack. E.g. RGB666 connect R5 and R6 together, B5 and B6 together to become RGB565. Then the least GPIO requirement can become 3(9-bit SPI) + 2(CD, WR) + 16(RBG565) = 21 pins. **Remember always pull down CS pin and always pull up RD pin.**

## Sponsor vs Support

As you may already aware there are seldom sponsors in this project. Convert it in terms of man power, it is much lower than a manhour each month. So don't expect too much on the support. Expecially the feature not realted to my planned maker projects ;>
