Code not work on STM32F103C8B6 + ILI9488(or ILI9486)

[brightproject]

Good day @Bodmer!
I'm probably not sure about the model of my display, it looks like this.

As far as I understand, it cannot be connected via SPI, but only a parallel connection.
I used the MCUFRIEND_kbv library and connected the display to the blue pill like this:

    //LCD pins  |D7 |D6 |D5 |D4 |D3 |D2 |D1 |D0 | |RD |WR |RS |CS |RST| |SD_SS|SD_DI|SD_DO|SD_SCK| !!!WORKED!!!
    //STM32 pin |PA7|PA6|PA5|PA4|PA3|PA2|PA1|PA0| |PB0|PB6|PB7|PB8|PB9| |PA15 |PB5  |PB4  |PB3   | **ALT-SPI1**

Through this library, the display is defined as 9486

and worked perfectO!

I want to make the display work with the library TFT_eSPI .
Using the library TFT_eSPI I uncommented the line in User_Setup_Select.h and specified the following settings in this file
#include <User_Setups/Setup30_ILI9341_Parallel_STM32.h> // Setup for Nucleo board and parallel display

#define USER_SETUP_ID 30

// See SetupX_Template.h for all options available

// Define STM32 to invoke optimised processor support
#define STM32

// Defining the board allows the library to optimise the performance
// for UNO compatible "MCUfriend" style shields
//#define NUCLEO_64_TFT
//#define NUCLEO_144_TFT

// Tell the library to use 8 bit parallel mode (otherwise SPI is assumed)
//#define TFT_PARALLEL_8_BIT
#define TFT_PARALLEL_16_BIT

// Define the display driver chip type
//#define ILI9341_DRIVER
#define ILI9486_DRIVER

// Define the Nucleo 64/144 pins used for the parallel interface TFT
// The pins can be changed here but these are the ones used by the
// common "MCUfriend" shields
#define TFT_CS   PB8  // Chip select control pin
#define TFT_DC   PB7  // Data Command control pin
#define TFT_RST  PB9  // Reset pin

#define TFT_WR   PB6  // Write strobe control pin 
#define TFT_RD   PB0  // Read pin

#define TFT_D0   PA0  // 8 bit parallel bus to TFT
#define TFT_D1   PA1
#define TFT_D2   PA2
#define TFT_D3   PA3
#define TFT_D4   PA4
#define TFT_D5   PA5
#define TFT_D6   PA6
#define TFT_D7   PA7

// Fonts to be available
#define LOAD_GLCD   // Font 1. Original Adafruit 8 pixel font needs ~1820 bytes in FLASH
#define LOAD_FONT2  // Font 2. Small 16 pixel high font, needs ~3534 bytes in FLASH, 96 characters

#define LOAD_FONT7  // Font 7. 7 segment 48 pixel font, needs ~2438 bytes in FLASH, only characters 1234567890:.
#define LOAD_FONT8  // Font 8. Large 75 pixel font needs ~3256 bytes in FLASH, only characters 1234567890:-.

// STM32 support for smooth fonts via program memory (FLASH) arrays

Please tell me:

1. Am I connecting the display correctly?
2. Does my display work with this library?
3. Whether the display is connected via SPI or only parallel connection, through 13 pins?
4. Can the library TFT_eSPI determine the display model or ID?

[Bodmer]

1. Yes
2. Yes
3. 8 bit parallel is OK
4. No

You need to change the setup file to 8 bit parallel;
#define TFT_PARALLEL_8_BIT
//#define TFT_PARALLEL_16_BIT
