Marlin firmware - integrating touchscreen on ender 3

Question

I am struggling to integrate the touchscreen in custom edited marlin firmware

The display is already flashed with DWIN and I've got this far:

• built the bin file and flashed it on the printer board (4.2.7 silent mb)
• the touch screen is responsive and I can shuffle through the menu

Problems:

• the text (en language) is not displayed on the bmps shown on the display
• when I blindly (intuitively tapping on pictograms because no text is shown on them lol) feed commands to the printer, nothing happens

Configuration.h changes:

1. //#define CR10_STOCKDISPLAY (commented stock display)
2. #define DGUS_LCD_UI_FYSETC (removed comment for that specific display - don't know if it's the right display but I found it in a DWIN set of displays)

// Show the Marlin bootscreen on startup. ** ENABLE FOR PRODUCTION **
//#define SHOW_BOOTSCREEN

// Show the bitmap in Marlin/_Bootscreen.h on startup.
//#define SHOW_CUSTOM_BOOTSCREEN

// Show the bitmap in Marlin/_Statusscreen.h on the status screen.
//#define CUSTOM_STATUS_SCREEN_IMAGE

(commented bootscreen, custom bootscreen and status screen definitions)

Answer 1

through lots of playing around i managed to get something to work

1. flashed DWIN 3.5 onto the display from https://github.com/CR6Community/CR-6-touchscreen/releases/tag/Re-Factored_v1.1 and placing DGUS2 kernel/T5L_UI_DGUS2_V35_20200730.BIN onto an SD in a folder called DWIN_SET
2. uploaded firmware to display from https://github.com/InsanityAutomation/Marlin/tree/CrealityDwin_2.0 using this file CombinedLandscapeDwin_TM3D_V8.7z placing the DWIN_SET folder on the SD card removing everything from step 1
3. compiled marlin bugfix-2.1.x with the following options in Configuration.h. Note started from the https://github.com/MarlinFirmware/Configurations/tree/import-2.1.x/config/examples/Creality/Ender-3/CrealityV427

#define DGUS_LCD_UI IA_CREALITY

//#define CR10_STOCKDISPLAY

#define CLASSIC_JERK

#define NOZZLE_PARK_FEATURE

4. edited to following options in Configuration_adv.h

#define ADVANCED_PAUSE_FEATURE

im sure there are other sources for these files but was happy to get it working. only thing, can only get it to work in landscape mode. the LCD_SCREEN_ROTATE did not display properly.

hope this help if you find out more post back
