In the platformio.ini:
[env:MAKERF_ESP32S3]:-D TFT_BL=45
void init_tft()
{
tft.init();
tft.setRotation(8);
tft.initDMA();
tft.startWrite();
tft.fillScreen(TFT_BLACK);
tft.endWrite();

gpio_set_drive_capability(GPIO_NUM_33, GPIO_DRIVE_CAP_3);
ledcAttachPin(TFT_BL, 0);

Now, my board is 16 bit parallel tft with driver FT6236, how can i define the drivers for it?
I can not find the driver setting for my 16 bit parrallel with dirver ft6236.
Waiting for you replaying.

Parallel definition is here https://github.com/jgauchia/IceNav-v3/blob/master/lib%2Fpanel%2FILI9488_FT5x06_16B.hpp and here https://github.com/jgauchia/IceNav-v3/blob/master/include%2Fhal.hpp

Add buildflag in platformio, see readme

I can not understand.
At first, my board is 16 bit parallel tft with driver FT6236(not ft5x06);
In fact, without any change, now i can touch my board use the code of you, maybe it is slow touch feel.
If i want to add the support for the ili9488 with 16 bit parallel FT6236 board, i should create a FILI9488_FT6236_16B.hpp, and then where to include the FILI9488_FT6236_16B.hpp file?
Should i change the hal.hpp? what the relationship between hal.hpp and FILI9488_FT6236_16B.hpp?

At last, will i add a buildflag in .ino file? like -D ILI9488_FT6236_16B = 1? how will the project build it with -D? i cannot find it.

void init_tft()
{
tft.init();
tft.setRotation(8);
tft.initDMA();
tft.startWrite();
tft.fillScreen(TFT_BLACK);
tft.endWrite();

gpio_set_drive_capability(GPIO_NUM_33, GPIO_DRIVE_CAP_3);
ledcAttachPin(TFT_BL, 0);

what the relationship between above codes with my -D ILI9488_FT6236_16B = 1?

So boring, waiting for you replying.

FT5x06 is a generic touch driver for i2c FT touch chip series. It's fully compatible

In fact, without any change, now i can touch my board use the code of you, maybe it is slow touch feel.

How do you feel it's slow? I don't understand you, there are image in TFT? Yes or not?

If i want to add the support for the ili9488 with 16 bit parallel FT6236 board, i should create a FILI9488_FT6236_16B.hpp, and then where to include the FILI9488_FT6236_16B.hpp file?

Why do you need yo create a new include file? There are one file for It, only do you need to check GPIO pin definitions in hal.hpp file

Should i change the hal.hpp? what the relationship between hal.hpp and FILI9488_FT6236_16B.hpp?

In hal.hpp file are the gpio definition for the screen , pleade check It and made necessary changes If you need

At last, will i add a buildflag in .ino file? like -D ILI9488_FT6236_16B = 1? how will the project build it with -D? i cannot find it.

No, you need to add buildflag at platformio.ini. in this file you set-up your environment (ESP model, GPS, etc..)

void init_tft()
{
tft.init();
tft.setRotation(8);
tft.initDMA();
tft.startWrite();
tft.fillScreen(TFT_BLACK);
tft.endWrite();

gpio_set_drive_capability(GPIO_NUM_33, GPIO_DRIVE_CAP_3);
ledcAttachPin(TFT_BL, 0);

what the relationship between above codes with my -D ILI9488_FT6236_16B = 1?

This is TFT init Code. This is independent from the panel or TFT choosed.

With the build-flag, you choose the Tft model and create the configuration for It.

So boring, waiting for you replying.
