// For RP2040 processor and 8 or 16 bit parallel displays:
// The parallel interface write cycle period is derived from a division of the CPU clock
// speed so scales with the processor clock. This means that the divider ratio may need
// to be increased when overclocking. I may also need to be adjusted dependant on the
// display controller type (ILI94341, HX8357C etc). If RP2040_PIO_CLK_DIV is not defined
// the library will set default values which may not suit your display.
// The display controller data sheet will specify the minimum write cycle period. The
// controllers often work reliably for shorter periods, however if the period is too short
// the display may not initialise or graphics will become corrupted.
// PIO write cycle frequency = (CPU clock/(4 * RP2040_PIO_CLK_DIV))
//#define RP2040_PIO_CLK_DIV 1 // 32ns write cycle at 125MHz CPU clock
#define RP2040_PIO_CLK_DIV 2 // 64ns write cycle at 125MHz CPU clock
//#define RP2040_PIO_CLK_DIV 3 // 96ns write cycle at 125MHz CPU clock
Sprite class uses TFT_eSPI setBitmapColor - fn deleted
Small performance improvement to RP2040 SPI PIO
Typo corrections
Correct (unused) tft_Write_32 for STM32
Update HX8357D rotation code
Enable software reset for ILI9486
Add preliminary RM68120 support
In setup add the following lines:
// If green and blue swapped on display then change the RGB colour order
// Only uncomment ONE of the following options
#define TFT_RGB_ORDER TFT_RGB // Red-Green-Blue
//#define TFT_RGB_ORDER TFT_BGR // Blue-Green-RED
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.
Simplified driver ST7789_2_DRIVER not supports 135 x 240 display.
This will not fix#763 since user specifies alternative ST7789_DRIVER which already supports 135x240 displays.
The SSD1963 support has been tested with a 480x800 pixel display from Buy Display.
Support for reading an ST7796 SPI display has been added.
pushToSprite added to keywords list.
#740: To avoid ambiguity the pushSprite for writing a sprite to another sprite has been renamed pushToSprite
#704: Change to 18 bit colurs for SSD1963 with SPI interface
Remove outdated TFT_SPIFFS_Jpeg example
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.
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.
