Fix issue when using ESP32 & using multiple TFT displays & not defining TFT_CS.
Note: Future support for multiple displays in all possible hardware combinations may not be practical.
New function added:
bool created(void);
to check if sprite has been rotated. Example:
if ( !spr.created() ) Serial.println("Sprite has not been created");
TFT_eFEX also needs updating so Rotated_Sprite_3 example renders correctly.
pushImage for FLASH images updated so partly off-screen images are correctly rendered.
Read_User_Setup updated to be compatible with STM32 and new structure format.
Reduction in compiler warnings
Update Sprite destructor
Update version to 2.2.1
Boost performance for ILI9488 display with STM32 processors.
Enable smooth fonts in setup files (smooth fonts for STM32 processors is now supported with fonts in program memory)
Typical use to disable use of PSRAM for the sprite storage:
sprite.setAttribute(PSRAM_ENABLE, false); // true to enable
Minor update for recent button class update
Added 24 bit colour handling alphaBlend to reduce precision loss in multiple blend stages (e.g. in 2D colour gradients). Added option for alpha dither to reduce colour banding in gradients with 16 bit colours.
Get rid of compile warnings.
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.
Callback allows anitaliased fonts to be rendered over colour gradients
or images.
"Smooth_font_reading_TFT" example added
"Smooth_font_gradient" example added
Minor changes to avoid signed/unsigned comparison warnings.
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.
Corrected font 2 rendering issue #402
Corrected NULL pointer issue #400
Changed grave ` character (key for this character is left of numeral 1
key) to degree symbol in font 2
Change setup24 so DC pin is not D3
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
