[BUG] TOUCH_IDLE_SLEEP_MINS does not work with TFT_COLOR_UI

[spasecookee]

Did you test the latest bugfix-2.1.x code?

Yes, and the problem still exists.

Bug Description

In Marlin 2.0.9 it is possible to use TFT_COLOR_UI, with a generic TFT (FSMC), TOUCH_SCREEN and a value for TOUCH_IDLE_SLEEP. In 2.1.1, this combination causes an error when Linking:

Marlin\src\lcd/marlinui.cpp:1183: undefined reference to `MarlinUI::sleep_display(bool)'

If TFT_CLASSIC_UI is used, there is no linking error, but it should also work with TFT_COLOR_UI.

Bug Timeline

This is a newer issue

Expected behavior

I expect linking should succeed.

Actual behavior

Linking fails with Marlin\src\lcd/marlinui.cpp:1183: undefined reference to `MarlinUI::sleep_display(bool)'

Steps to Reproduce

In Configuration.h, set BOARD_CHITU3D_V6
Set SERIAL_PORT 1
Set TFT_GENERIC
Set TFT_DRIVER ILI9488
Set TFT_INTERFACE_FSMC
Set TFT_RES_480x320
Set TFT_COLOR_UI
Set TOUCH_SCREEN
Set TOUCH_IDLE_SLEEP_MINS 5

try enabling the LCD_BACKLIGHT_TIMEOUT
in settings.cpp
under TERN(HAS_LCD_BRIGHTNESS, ui.refresh_brightness());

add TERN_(LCD_BACKLIGHT_TIMEOUT, ui.refresh_backlight_timeout());

in dwin.cpp (ProUI)
add to advancedsettings menu
#if LCD_BACKLIGHT_TIMEOUT EDIT_ITEM(ICON_Box, MSG_LCD_TIMEOUT_SEC, onDrawPIntMenu, SetTimer, &ui.lcd_backlight_timeout); //added #endif
then add the function

  #if LCD_BACKLIGHT_TIMEOUT
  void SetTimer()   { SetPIntOnClick(LCD_BKL_TIMEOUT_MIN * 10, LCD_BKL_TIMEOUT_MAX);
    DWIN_UpdateLCD();
   }
  #endif

under HMI_Init()
add

#if LCD_BACKLIGHT_TIMEOUT
      ui.refresh_backlight_timeout();
    #endif  

and under EachMomentUpdate()

 #if LCD_BACKLIGHT_TIMEOUT
    if (ui.backlight_off_ms && ELAPSED(ms, ui.backlight_off_ms)) {
      TurnOffBacklight(); ; // Backlight off
      ui.backlight_off_ms = 0;
    }
  #endif

you may have to add
const millis_t ms = millis(); to marlinui.cpp
under if LCD_BACKLIGHT_TIMEOUT

@classicrocker883 I just want to verify something, the actual setting in Configuration_adv.h is now
LCD_BACKLIGHT_TIMEOUT_MINS not LCD_BACKLIGHT_TIMEOUT. In any case, enabling LCD_BACKLIGHT_TIMEOUT_MINS causes an erorr in SanityCheck.h: "LCD_BACKLIGHT_TIMEOUT_MINS requires LCD_BACKLIGHT_PIN."

I appreciate the suggestions, however.
