* Add smooth arc drawing function
Update ESP8266 architecture reference
Add pushMaskedImage() to render 16bpp images with a 1bpp mask (used for transparent PNG images plus with sprites)
New functions added using drawArc:
drawSmoothArc
drawSmoothCircle
drawSmoothRoundRect
New sqrt_fraction() added to improve smooth graphics performance on processors without a FPU (e.g. RP2040)
Faster alphaBlend() function added which retains 6bpp for green
Rename swap_coord() to transpose()
* Update TFT_eSPI.cpp
* Add arc examples
The TFT configuration (user setup) can now be included inside an Arduino IDE sketch providing the instructions in the example Generic->Sketch_with_tft_setup are followed. See ReadMe tab in that sketch for the instructions.
A new background rendering approach is used for smooth fonts which almost eliminates flicker. tft.print... can now be used with a background rendered for smooth fonts. Font_Demo_1/2/3... examples have been updated.
A new "docs" folder has been created and files moved there. The Tools folder now only contains support tools.
#1757 fixed by using Arduino calls.
A new USER_SETUP_ID parameter can be added to setup files and checked via a new verifySetupID(id); function.
Version raised to v2.4.50
The RP2040 processors can now drive 8 bit parallel and SPI displays using the PIO hardware.
The PIO offloads the processor by providing:
1. PIO managed setWindow sequence
2. PIO managed block and screen fill
Add ILI9225 support
Add viewport feature to Sprites
Rationalise common TFT_eSPI and Sprite functions and variables to use inherited functions width(), height(), rotation(), write(), pivot, cursor, swapBytes.
The ESP8266 has the LittleFS Flash filing system which is significantly faster than SPIFFS. New Smooth Font examples have been added that use LittleFS.
