TFT_eSPI setup file for 3.5" RGB version?

[henkjannl]

Hi,

It looks like the file:

..\GitHub\CrowPanel-ESP32-Display-Course-File\CrowPanel_ESP32_Tutorial\File\TFT_eSPI Setup file\3.5inch\User_Setup.h

Is currently intended for the SPI version of the 3.5" display:

// For ESP32 Dev board (only tested with GC9A01 display)
// The hardware SPI can be mapped to any pins
#define TFT_MISO 12
#define TFT_MOSI 13 // In some display driver board, it might be written as "SDA" and so on.
#define TFT_SCLK 14
#define TFT_CS   15  // Chip select control pin
#define TFT_DC   2  // Data Command control pin
#define TFT_RST  -1  // Reset pin (could connect to Arduino RESET pin)
#define TFT_BL   27  // LED back-light

#define TOUCH_CS 33     // Chip select pin (T_CS) of touch screen

I was suspecting something like:

#define TFT_D0   47  // Must use pins in the range 0-31 for the data bus
#define TFT_D1   21  // so a single register write sets/clears all bits.
#define TFT_D2   14  // Pins can be randomly assigned, this does not affect
#define TFT_D3   13  // TFT screen update performance.
#define TFT_D4   12
#define TFT_D5   11
#define TFT_D6   10
#define TFT_D7    9

#define TFT_D8    3
#define TFT_D9    8
#define TFT_D10  16
#define TFT_D11  15
#define TFT_D12   7
#define TFT_D13   6
#define TFT_D14   5
#define TFT_D15   4

But it looks like tft_espi is only accepting 16 bits parallel IO for an experimental version with the Raspberry Pi.

How can I configure my project for the parallel RGB version?

Kind regards,
