16-bit parallel with the ILI9488 and ESP32-S3

[Googool]

Hello there!

I have been looking around for a tutorial (or explanation) on how to connect the ESP32-S3 to a display (ILI9488 driver) in the 16-bit parallel configuration.

Can I just connect them as shown in this setup file? Or do I have to use other pin connections?
https://github.com/Bodmer/TFT_eSPI/blob/master/User_Setups/Setup107_RP2040_ILI9341_16bit_parallel.h

// These pins can be moved and are controlled directly by the library software
#define TFT_RST   18  // Reset pin
#define TFT_CS    19  // Do not define if chip select control pin permanently connected to 0V
//#define TFT_RD   -1   // Do not define, read pin must be permanently connected to 3V3

// Note: All the following pins are PIO hardware configured and driven
#define TFT_WR   16    // Write strobe pin
#define TFT_DC   17    // Data Command control pin

 // PIO requires these to be sequentially increasing
#define TFT_D0    0
#define TFT_D1    1
#define TFT_D2    2
#define TFT_D3    3
#define TFT_D4    4
#define TFT_D5    5
#define TFT_D6    6
#define TFT_D7    7
#define TFT_D8    8
#define TFT_D9    9
#define TFT_D10  10
#define TFT_D11  11
#define TFT_D12  12
#define TFT_D13  13
#define TFT_D14  14
#define TFT_D15  15

And is there an explanation of why PlatformIO wants the pins to be sequentially increased like shown above? Saw someone using the LovyanGFX library but not with sequentially increasing pin numbers.

If anyone has the pin connections from the ESP32-S3 to the display (ILI9488) in 16-bit parallel laying around and is willing to show, share or tell how they did it - would be greatly appreciated!

The library only supports 8 bit parallel interfaces with the ESP32 family. The 16 bit interface is only supported with RP2040 processors (e.g. Raspberry Pico).

Hello Bodmer, I am confused about the 8bit and 16bit issue above,

Makerfabs say their MaTouch_ESP32-S3 Parallel TFT with Touch 3.5'' ILI9488 is a 16bit utilizing an ESP32-S3-WROOM-1-N16R2 micro???

I am attempting to pass live, real-time GPS data from an TTGO T7 V1.3 ESP32-WROOM to the Makerfabs ESP32-S3_Wroom equipped ILI9488 LCD Display (referenced below) via I2C communication. However I am not able to achieve communication beyond basic chip info, attachment I2C does not receive data.png.
