Adafruit_GFX font support extended to Unidode Basic Multilingual Plane
Print stream deocdes UTF-8
Smooth font ascent and descent (affects line spacing) changed to rely on
metrics provided by Processing IDE (issue #303)
Bug fix for font rendering with no background on RLE native fonts
Supports Adafruit_GFX compatible font format with characters in the range 32-255.
Note that the font rendering functions expect UTF-8 encoded characters/strings.
There is a bug in the ESP8266 Arduino core that averwrites the overlap
mode setup and hold bits for the hardware driven SPI SS line. The
TFT_eSPI library has been patched as a work-around.
In overlap mode to maintain the required setup and hold times at 80MHz
ESP8266 CPU clock the SPI rate must be 27MHz or less. At 160MHz CPU
clock the SPI rate can be 40MHz.
Add bounds checking to graphics functions
Rationalise variable types and style used to minimse type casting needs
(this change ended up being a more extensive refactoring than
anticipated - but once started...)
Add version reporting to diagnostic sketch
Boost PDQ graphicstest performance
If the VSPI port is in use and pins are not accessible (e.g. TTGO
T-Beam)
then add or uncomment the following line in the setup header file:
//#define USE_HSPI_PORT
Minor performance tweaks for ESP32 to minimise the occurence of the slow
transaction overhead.
setAddrWindow now takes xstart, ystart, width and height as inputs
Multi-sample raw touch x and y for noisy displays
Example update for setAddrWindow change compatibility
Speed up Sprite rotation on an ESP32
Update utf8 serial decoder to handle illegal format strings
Remove need for D0_USED_FOR_xx (issue #271)
Clean up setup files
Correct various comment typos
Sprites can be rendered rotated with defined pivot points, 3 new
examples have been added "Rotated_Sprite_1/2/3".
The FLASH bitmap example has been moved to the Generic examples folder.
Boundary checks have been added to pushImage()
A new scrolling and wrapping in a Sprite example has been added.
Added new function that sketch can call to convert raw ADC x and y
values to calibrated screen coordinates:
tft.convertRawXY(&x, &y);
Redunced required number of SPI transfers needed to read raw values.
Changed mode so PENIRQ pin is enabled so users sketch can read this
signal (if needed).
See issue #279.
Fixed bug where wrong wodth was returned for 1bpp Sprite
Improved speed for copying a 1bpp Sprite into another 1bpp Sprite (
affects Sprite pushImage() function only)
Added option to setup for colour inversion
Arduino library manager picked up the wrong release.
This version raise is to forece a new release to be recognised. Releases
1.3.2 and 1.3.3 have been deleted.
Tested on ESP32 and ST7789V display only. It may not work with other
displays!
Use:
#define TFT_SDA_READ
in setup file to use bi-directional SDA pin support.
Tested on an ESP32 with ST7789V display
SDA read is very slow on an ESP8266 (to be investigated)
Added new setup #define TFT_SDA_READ
Add new ESP32 and ESP8266 compatible in example/Generic folder to test
capture of TFT screen
// 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
