||
| This directory is intended for project header files. | ||
|
|
||
| A header file is a file containing C declarations and macro definitions | ||
| to be shared between several project source files. You request the use of a | ||
| header file in your project source file (C, C++, etc) located in `src` folder | ||
| by including it, with the C preprocessing directive `#include'. | ||
|
|
||
| ```src/main.c | ||
|
|
||
| #include "header.h" | ||
|
|
||
| int main (void) | ||
| { | ||
| ... | ||
| } | ||
| ``` | ||
|
|
||
| Including a header file produces the same results as copying the header file | ||
| into each source file that needs it. Such copying would be time-consuming | ||
| and error-prone. With a header file, the related declarations appear | ||
| in only one place. If they need to be changed, they can be changed in one | ||
| place, and programs that include the header file will automatically use the | ||
| new version when next recompiled. The header file eliminates the labor of | ||
| finding and changing all the copies as well as the risk that a failure to | ||
| find one copy will result in inconsistencies within a program. | ||
|
|
||
| In C, the usual convention is to give header files names that end with `.h'. | ||
| It is most portable to use only letters, digits, dashes, and underscores in | ||
| header file names, and at most one dot. | ||
|
|

| # Arduino_GFX | ||
|
|
||
| Arduino_GFX is a Arduino graphics library supporting various displays with various data bus interfaces. | ||
|
|
||
| This library start rewrite from Adafruit_GFX, TFT_eSPI, Ucglib and more... | ||
|
|
||
| ## Various dat bus interfaces | ||
|
|
||
| Most tiny display in hobbiest electronics world support 8-bit SPI, but some require 9-bit SPI. 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 require 9-bit SPI interface. | ||
|
|
||
| Larger display most likely not support standalone SPI since it is not fast enough to refresh the full screen details. Most of them can use 8-bit/16-bit Parallel interface. | ||
|
|
||
| ## Ease of use | ||
| #### Simple Declaration | ||
| (not require touch the header files in libraries folder) | ||
| ```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 | ||
| ``` | ||
| gfx->begin(); | ||
| gfx->fillScreen(BLACK); | ||
| gfx->setCursor(10, 10); | ||
| gfx->setTextColor(RED); | ||
| gfx->println("Hello World!"); | ||
| ``` | ||
|
|
||
|
|
||
| ## Performance | ||
| 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. | ||
| - Arduino IDE: 1.8.10 | ||
| - MCU: ESP32-PICO-D4 | ||
| - PSRAM: disable | ||
| - Display: ILI9341 | ||
| - Interface: SPI@40MHz | ||
| - Test time: 2019 Oct 13 | ||
