TFT LCD Display Module 480X320 driven with FSMC

I have recently bought a 3.5" inch TFT LCD Touch Screen Display Module 480X320 with a www.mcufriend.com label on the back side. The display was equipped with an 8bit parallel interface. First I decided to test it with the UniGraphic library using the BUS_8 protocol. The display was very slow but improved when I switched to the PAR_8 protocol. Because I heard about the possibility to use a Flexible Static Memory Controller (FSMC), built into some STM MCU's, to drive LCD's (read/write to LCD's memory rather than to an external SRAM) I thought it would be a fun to try it out.

Below is the brief story of what I did:

Created a project for my STM32F407VE board in the STM32CubeIDE
Set the Clock Configuration to match the one used by Mbed for the Seeed Arch Max board:

Selected FSMC in the Connectivity category and configured it as below:
Let the STM32CubeIDE generate the code (files).
Created a new program for the Seeed Arch Max target in the Mbed Online Compiler by selecting a mbed os blinky template.
Replaced the main.cpp with the main.c content of the STM32CubeIDE project.
Copy & Pasted the other files with codes from the STM32CubeIDE project to the online compiler project.
Renamed and modified:
"stm32f4xx_it.h" to "stm32f4xx_it_msp.h"
"stm32f4xx_it.c" to "stm32f4xx_it_msp.c"
Added the UniGraphic library to the online compiler project.
Extended the UniGraphic library with a FSMC_8 protocol and replaced the TFT::set_orientation(int orient) function with the one used by mcufriend for arduino.
Modified the main.cpp as needed.
