// 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
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
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
I have a SeeedStudio Wio Terminal.
I'm using this lib in VS Code with PlatformIO but the lib
don't use the `SPICOM` variable when it's a generic device.
Steps to reproduce (using a Wio Terminal):
* Create a project using PlatformIO
* Add the TFT_eSPI lib to the project
* Add in the build flags these lines
```
build_flags =
-DUSER_SETUP_LOADED=1
-DILI9341_DRIVER=1
-DHASSPI=1
-DSPICOM=LCD_SPI
-DTFT_CS=LCD_SS_PIN
-DTFT_DC=LCD_DC
-DTFT_RST=LCD_RESET
-DTFT_BL=LCD_BACKLIGHT
-DTFT_BACKLIGHT_ON=HIGH
-DTFT_BACKLINGT_V=2000
```
* Compile and transfer to the device
=> only backlight works
