ILI9486 with Nodemcu-32S, 8bit parallel wiring

[Haimana]

Hello,

I'm trying to connect a 3.5 TFT display, like the one from the first post to a Nodemcu-32s, using 8bit parallel wiring, no touch.

I also need to have the wifi functional and I use different GPIOs.
Because I use Platformio/VS Code, I tried to use the platformio.ini for configuring my display, and not to edit the library's User_Setup.h file.

My platformio.ini looks like this:

[env:nodemcu-32s]
platform = espressif32
board = nodemcu-32s
framework = arduino
lib_deps = bodmer/TFT_eSPI@^2.5.43

build_flags =
	-D USER_SETUP_LOADED
	-D ESP32_PARALLEL
	-D ILI9486_DRIVER
	-D PSEUDO_16_BIT
	-D TFT_RD=-1  	;RD pin not used, set to -1
	-D TFT_WR=4  	;Write strobe pin
	-D TFT_DC=5  	;Data/command pin
	-D TFT_CS=21  	;Chip select pin
	-D TFT_RST=22	;Reset pin

	-D TFT_D0=12
	-D TFT_D1=13 
	-D TFT_D2=14
	-D TFT_D3=15 
	-D TFT_D4=16
	-D TFT_D5=17
	-D TFT_D6=18
	-D TFT_D7=19

	-D LOAD_GLCD=1
	-D LOAD_FONT2=1
	-D LOAD_FONT4=1
	-D LOAD_FONT6=1
	-D LOAD_FONT7=1
	-D LOAD_FONT8=1
	-D LOAD_GFXFF=1
	-D SMOOTH_FONT=1
	-D SPI_FREQUENCY=27000000

But my display have a lot of glitches and after a while turns full white.
For pseudo mode, I made the connections like this:

Connect D0 to D8
Connect D1 to D9
Connect D2 to D10
Connect D3 to D11
Connect D4 to D12
Connect D5 to D13
Connect D6 to D14
Connect D7 to D15

Obviously I'm doing something wrong or I forgot something because first time, when I had the User_setup file edited, the display was OK but my modifications was lost, rewritten by platformio at some "wrong move" of mine. So I am not able to compare with what I did there and it worked with what is not done right in this setup.
If need it (I mean no obvious errors in my setup), I can upload some pics, but for now I'm trying to keep the topic as clean as possible

Thank you for your time and help
