[BUG] Can't compile anything with Build Flag "-DLCD_BTT_TFT"

[gfacek]

Bug Description

I tried to compile marlin-lux-marlin-2.0.9.2 with the following settings in luxuri.ini:

[env:D2P_OCTOPUS_Driver2209BTT_OpticalY_BLTouch_LCD_BTT_TFT]
platform           = ${common_stm32.platform}
extends            = stm32_variant
board              = marlin_BigTree_Octopus_v1
board_build.offset = 0x8000
build_flags       = ${stm32_variant.build_flags} -DMachineTLD2P -DOCTOPUS -DDriver2209BTT -DOpticalY -DBL_Touch -DLCD_BTT_TFT -DSTM32F446_5VX -DUSE_USB_HS_IN_FS

The compilation failed with the following errors:
Marlin\src\lcd\dogm\ultralcd_st7920_u8glib_rrd_AVR.cpp:49:29: error: token "{" is not valid in preprocessor expressions Marlin\src\lcd\dogm\ultralcd_st7920_u8glib_rrd_AVR.cpp:65:29: error: token "{" is not valid in preprocessor expressions Marlin\src\lcd\dogm\ultralcd_st7920_u8glib_rrd_AVR.cpp:81:29: error: token "{" is not valid in preprocessor expressions

Bug Timeline

No response

Expected behavior

I expected to compile the firmware.bin regarding the selected settings.

Actual behavior

The firmware-file did not compile. Instead I got the following error:
Marlin\src\lcd\dogm\ultralcd_st7920_u8glib_rrd_AVR.cpp:49:29: error: token "{" is not valid in preprocessor expressions Marlin\src\lcd\dogm\ultralcd_st7920_u8glib_rrd_AVR.cpp:65:29: error: token "{" is not valid in preprocessor expressions Marlin\src\lcd\dogm\ultralcd_st7920_u8glib_rrd_AVR.cpp:81:29: error: token "{" is not valid in preprocessor expressions

Steps to Reproduce

1. Add the following configuration in luxuri.ini:

[env:D2P_OCTOPUS_Driver2209BTT_OpticalY_BLTouch_LCD_BTT_TFT]
platform           = ${common_stm32.platform}
extends            = stm32_variant
board              = marlin_BigTree_Octopus_v1
board_build.offset = 0x8000
build_flags       = ${stm32_variant.build_flags} -DMachineTLD2P -DOCTOPUS -DDriver2209BTT -DOpticalY -DBL_Touch -DLCD_BTT_TFT -DSTM32F446_5VX -DUSE_USB_HS_IN_FS

2. Select the configuration in platformio.ini as default env:
   default_envs = D2P_OCTOPUS_Driver2209BTT_OpticalY_BLTouch_LCD_BTT_TFT
3. Compile

Found a solution:

in Marlin/src/pins/stm32f4/pins_BTT_OCTOPUS_V1_common.h there is this part:

#if HAS_MARLINUI_U8GLIB
  #ifndef BOARD_ST7920_DELAY_1
    #define BOARD_ST7920_DELAY_1   DELAY_NS(120)  // DELAY_NS(96)
  #endif
  #ifndef BOARD_ST7920_DELAY_2
    #define BOARD_ST7920_DELAY_2   DELAY_NS(80)   // DELAY_NS(48)
  #endif
  #ifndef BOARD_ST7920_DELAY_3
    #define BOARD_ST7920_DELAY_3   DELAY_NS(580)  // DELAY_NS(600)
  #endif
#endif

I had to change it to:

#if HAS_MARLINUI_U8GLIB
  #ifndef BOARD_ST7920_DELAY_1
    #define BOARD_ST7920_DELAY_1   120  // DELAY_NS(96)
  #endif
  #ifndef BOARD_ST7920_DELAY_2
    #define BOARD_ST7920_DELAY_2   80   // DELAY_NS(48)
  #endif
  #ifndef BOARD_ST7920_DELAY_3
    #define BOARD_ST7920_DELAY_3   580  // DELAY_NS(600)
  #endif
#endif

Great work! This one has stumped us. I'm keeping this bug open until it can be implemented in our new Marlin 2.1x build. Please join us in Discord if you haven't already:
