User selection for new TTGO ESP32-S3 with 170x320 display

[MartinNohr]

Is there a user choice for the TTGO ESP32-S3 with 170x320 display. This is the new version of the TTGO T-Display.

[Bodmer]

I assume it is this board:

http://www.lilygo.cn/prod_view.aspx?TypeId=50062&Id=1411&FId=t3:50062:3

Which has an 8 bit paralel interface.

It should be possible to adapt this setup file by changing the pins used:

https://github.com/Bodmer/TFT_eSPI/blob/master/User_Setups/Setup70d_ILI9488_S3_Parallel.h

[Bodmer]

I see the display uses GPIO pins that are higher than 31 so the library is not compatible at the moment.

[Bodmer]

It looks like a modified library is included here:

https://github.com/Xinyuan-LilyGO/T-Display-S3

[MartinNohr]

If that board becomes popular, and I think it will, then I would think these changes should be incorporated into the main code here.

[Bodmer]

See #1948

[gotnull]

Did we ever figure this out?

[Bodmer]

I created a temporary patch here:
#2134 (comment)

This allows high GPIO to be used. Let me know if it works for you.

The support will be added in the next library update, probably next week.

[Bodmer]

Support has been added to the branch here:

https://github.com/Bodmer/TFT_eSPI/tree/T-Display-S3

Please test and let me know if it works OK. There is a setup file for the display:
https://github.com/Bodmer/TFT_eSPI/blob/T-Display-S3/User_Setups/Setup206_LilyGo_T_Display_S3.h

This has already been selected in the seup file so the library should run straight away with no edits:
https://github.com/Bodmer/TFT_eSPI/blob/T-Display-S3/User_Setup_Select.h#L131

I have this board too, have tested the branch in PlatformIO. With bouncing circles example it gives 26.5fps. With all defines copied in it, platformio.ini is like

[env:T-Display-S3]
# ESP32-S3R8 (8MB PSRAM)
# Winbond 25Q128JVSQ (16MB flash)
# 1.14" TFT 170x320, ST7789, 8-bit parallel

Unrelated to display, when testing with 16MB partition schemes the board kept rebooting continuously.

[Bodmer]

Thanks for testing, I will merge soon.

[TangerineDreamer]

I have this one too,i'm glad you make an adaptation for the user setups,but it's not very perfect,
i use the TFT_clock sketch from the 160x128 repertory,here is the result as is (no change done to your setup) :

seems it keeps from the last memory sketch: graphic test one lib

[Bodmer]

Comment out this line and try again:
https://github.com/Bodmer/TFT_eSPI/blob/master/User_Setups/Setup206_LilyGo_T_Display_S3.h#L6

[TangerineDreamer]

Seems it's good now (you know the colors of the sketch):

[TangerineDreamer]

here's the benshmark results:

[Bodmer]

I have updated this file as there was a command missing:
https://github.com/Bodmer/TFT_eSPI/blob/master/TFT_Drivers/ST7789_Init.h

With this file replaced the line below can be reinstated and should improve the colour rendition:
https://github.com/Bodmer/TFT_eSPI/blob/master/User_Setups/Setup206_LilyGo_T_Display_S3.h#L6

The test results look good (that test clears the screen 60 times, hence the large clear screen time.

[TangerineDreamer]

hay bodmer,it works if the line:
#define INIT_SEQUENCE_3 is commented,so for me the good result is:
//#define INIT_SEQUENCE_3

[TangerineDreamer]

It's ok now with your very last update:
#define INIT_SEQUENCE_3 is let as is: uncomment
benshmark is same as before,glad that works :)

[eliliam]

Is this close to being merged? This would let us move forward over in ESPHome to add support for the board as well as its display.

[Bodmer]

Yes, it is in the master.
