The library has been cleaned up as it has got a bit untidy due to the large number of small incremental changes.
4bit Sprite examples renaed to be consistent with others.
alphaBlend example moved to generic folder (alphaBlend fn was moved to TFT_eSPI class).
Added sections + explanatory comments to functions prototypes.
Temporary comments added for potential gotchas for noobs when using DMA.
spi_begin/end functions renamed to reflect functionality. Old fns retained for backwards compatibility with user setup.h files.
Images/sprites overlapping both sides of the display were not correctly
cropped.
Option added to allow RGB<>BGR colourr swap option to be used.
ESP8266 Wemos D1 R1 pin numbering difference accomodated.
TTGO T4 setup changed to use HSPI port.
Added SD card storage for smooth fonts with ESP32
ESP32 will use PSRAM (if available and enabled) to hold smooth font
metrics
Improve performance of ESP32 Sprite shared functions
Add basic ST7789 driver option
Latent bug fixes for pin mask
// For ST7789 ONLY, define the colour order IF the blue and red are
swapped on your display
//#define TFT_RGB_ORDER TFT_RGB // Colour order Red-Green-Blue
//#define TFT_RGB_ORDER TFT_BGR // Colour order Blue-Green-Red
Four new examples have been added to show different methods of rendering
the anta-aliased fonts. A few minor bugs have been corrected associated
with the font rendering. drawNumber and drawFloat handle fixed width
mono fonts with no digit movement.
Also added ability to push 1bpp bitmaps to a Sprite to support rendering
images on an EPaper screen.
Floyd-Steinberg dithering and basic graphics example added as first
ePaper demo.
This is stage one of support for ePaper displays from Waveshare.
Examples for 1 bit per pixel Sprites and 2 or 3 colour ePaper displays
to follow soon.
Add interface driver macro
Add 8 bit parallel support
Add 8 bit parallel read support
Add ILI9481, ILI9488 and HX8357D drivers
Update version and ReadMe
Update Create_Font processing sketch
Add slightly narrower alternative font 8
1. Ability to swap bytes in pushColors() and pushImage()
2. pushImage() will handle FLASH stroed images
3. pushImage() will accept a transparent color
4. pushRect() deprecated but still works
5. setSwapBytes() to set swapping bytes in color for pushImage() and
pushColors() true or false
6. getSwapBytes() returns swap bytes parameter
7. fillCircle() and fillCircleHelper() changed to use horizontal lines
to speed up plotting in a sprite
8. fillTriangle bug fix by moving spi_begin()
9 Small performance improvement to setAddrWindow()
10. pushColor() bug fix for swapped bytes
11. pushColors() performance improvement for ESP8266 and add optional
byte swap parameter, accepts higher pixel count
12. move spi_begin() later in drawLine() incase fn returns early
13. add spi_end() in drawLine incdae return occurs early
14. Add color332() fn to convert 16 bit to 8 bit colour
15. Sprite: createSprite() checks if sprite already created and returns
pointer if it does
16. Sprite: one extra "off-screen pixel added to a sprite to point
out-of-bounds setWindow coords to
this avoids extra bounds checks in push/write color
17. Sprite: setColorDepth allows changing of depthe for existing sprtie
and returns a new pointer to the new sprite
18. Sprite: pushImage() accepts a swapped byte parameter
19. Sprite: setSwapBytes() to set swapping bytes in color for
pushImage() and pushColors() true or false
20. Sprite: getSwapBytes() returns swap bytes parameter
21. Sprite: setWindow deals with duff out of sprite coords.
22. Sprite: bug in draw char corrected which could draw too many
over-writing pixels
Adding ability to load settings from the calling program rather than modifying the library for each project that uses it. This is mostly for PlatformIO IDE which manages the libraries differently than Adruino IDE.
Sprites (images) can now be created in RAM, written to with text and
graphics and rendered to screen quickly, this makes it easier to get
flicker frre screen updates.
ESP8266 can typically create up to a 160x128 sprite, and ESP32 about
200x200 pixels. 16 bit colour only at the moment, may soon implement 8
bit colour to reduce RAM.
