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
- When the post-remapped coordinates exceed screen bounds, `getTouch()` was returning a "valid" status without updating the coordinates. This would result in spurious touch detection events at the screen boundaries.
- The fix ensures that the return value is set to "invalid" in this boundary condition.
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
Pixel function used wrong width and height for bounds check.
Remove String variable in smooth font code (not used)
Correct ESP8266UncannyEyes example for new setAddrWindow parameters
The touch screen handler was broken for the ESP8266 only. The library
uses SPI write only configuration for ESP8266 so the SPI buffer can be
recycled and it was left in write only mode. The library now switches
back to read & write mode at the end of a transaction.
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.
