* split tft folder in two: tft for color ui; tft_io for shared tft code * after the files got moved, now the code was moved to the right place * classic ui using TFT IO init lcd codes * feature to compile tft_io when enabled * compiling fix * lvgl spi tft working with tft io init codes * there is no need for separeted fsmc and spi class in lvgl anymore, as tft io handle everything * remove debug * base for TFT rotation and mirroring API, and ILI9488 support * ST7796S rotate and mirror support * ST7789V rotate and mirror support * ST7735 rotate and mirror support * ILI9341 rotate and mirror support * ILI9328 rotate and mirror support * R61505 rotate and mirror support * MKS TFT definitions * more configs for mks tfts * update config * naming typo * to configure the user interface * ANYCUBIC_TFT35 * tft configs * support for SSD1963 * tft display types * updated conditionals lcd; first board fully working with the new code - all 3 ui! * compatiblity * changed name * move classic ui file name * rename TURN -> ROTATE * GRAPHICAL_TFT_ROTATE_180 deprecated * first fsmc board fully working - chitu v5 * mks robin nano v1.2 + tft 35 ok! * right pin name * anycubic tft tested in a TRIGORILLA_PRO * chitu v6 * nano 32 tft orientation * mks tft43 * mks tft43 rotation * fixed LONGER LK tft setup * GRAPHICAL_TFT_UPSCALE defined by the display type * better offsets defaults * Update Configuration.h * Update tft_fsmc.cpp * Update Conditionals_LCD.h * Tweak comments * update nano tests * Revert "update nano tests" This reverts commit a071ebbfad30e28855a4a5695ec8a726542a1a65. * default tft * outdated comments * to not break non-vscode builds * upscale tft 35 * support tft 180 rotation for color ui * Each TFT Driver is responsible for its default color mode. * use auto detect in mks displays, because some of them could be shipped with diferent drivers * extra s * unused code * wrong -1 * missing mirror options * Smaller regex pattern * Comment updates * Clean up old defines * Apply pins formatting * GRAPHICAL_TFT_ROTATE_180 => TFT_ROTATE_180 * MKS_ROBIN_TFT_V1_1R * merge fix * correct resolution * auto is default, dont need be there, and it will allow the user to configure it even for named displays * to not use rotation with MKS_ROBIN_TFT_V1_1R * i like () in macros * avoid sleepy commits * default for st7789 is rgb * nano follow up * to allow ili9328 rotation * default is rgb * boards merge follow up * to match bootloader orientation * HAS_TOUCH_XPT2046 is not hal specific anymore * lets not forget LPC * 180 rotation for ili9328 and R61505 * Clean up whitespace Co-authored-by: Scott Lahteine <thinkyhead@users.noreply.github.com> Co-authored-by: Scott Lahteine <github@thinkyhead.com>

* Draw and Touch processing
|
|
*
|
|
* LCD_PIXEL_WIDTH/HEIGHT (128x64) is the (emulated DOGM) Pixel Drawing resolution.
|
|
* TOUCH_SENSOR_WIDTH/HEIGHT (320x240) is the Touch Area resolution.
|
|
* TFT_WIDTH/HEIGHT (320x240 or 480x320) is the Actual (FSMC) Display resolution.
|
|
*
|
|
* - All native (u8g) drawing is done in LCD_PIXEL_* (128x64)
|
|
* - The DOGM pixels are is upscaled 2-3x (as needed) for display.
|
|
* - Touch coordinates use TOUCH_SENSOR_* resolution and are converted to
|
|
* click and scroll-wheel events (emulating of a common DOGM display).
|
|
*
|
|
* TOUCH_SCREEN resolution exists to fit our calibration values. The original touch code was made
|
|
* and originally calibrated for 320x240. If you decide to change the resolution of the touch code,
|
|
* new calibration values will be needed.
|
|
*
|
|
* The Marlin menus are drawn scaled in the upper region of the screen. The bottom region (in a
|
|
* fixed location in TOUCH_SCREEN* coordinate space) is used for 4 general-purpose buttons to
|
|
* navigate and select menu items. Both regions are touchable.
|
|
*
|
|
* The Marlin screen touchable area starts at TFT_PIXEL_OFFSET_X/Y (translated to SCREEN_PCT_LEFT/TOP)
|
|
* and spans LCD_PIXEL_WIDTH/HEIGHT (scaled to SCREEN_PCT_WIDTH/HEIGHT).
