This library is developing aim for support various data bus interfaces and various displays.
As I know, it should be the first Arduino display library that can support ESP32 9-bit hardware SPI. It is very important to support the displays (e.g. HX8357B, ST7701, ...) that only have 9-bit SPI interface.
This library start rewrite from Adafruit_GFX, TFT_eSPI, Ucglib and more...
(not require modify library header files)
#include "Arduino_GFX_Library.h"
Arduino_DataBus *bus = new Arduino_HWSPI(16 /* DC */, 5 /* CS */);
Arduino_GFX *gfx = new Arduino_ILI9341(bus, 17 /* RST */);gfx->begin();
gfx->fillScreen(BLACK);
gfx->setCursor(10, 10);
gfx->setTextColor(RED);
gfx->println("Hello World!");
This library is not putting speed at the first priority, but still paid much effort to make the display look smooth. Below are some figures compare with other 2 Arduino common display libraries.
