LCD Board wiring

//STM32 pin |PA7|PA6|PA5|PA4|PA3|PA2|PA1|PA0| |PB0|PB6|PB7|PB8|PB9| |PA15 |PB5 |PB4 |PB3 |

The display works fine using MCUFriend_Kbv. I am not changing any of the wiring, just transferring the settings to TFT_eSPI
MCUFriend detects the display as a ili9486. with 8 bit parallel
I have pasted my platformio.ini and defines from main.cpp which is just the color_test.ino file

What I am getting is nothing on the display at all, just white.

Any thoughts on what I am doing wrong?

See example here.

Note in particular the line:
-DUSER_SETUP_LOADED=1

Run the Read_User_Setup diagnostic sketch to see if the compiler is picking up the right settings.

Now need to select the parallel interface to the setup list by adding:

-D TFT_PARALLEL_8_BIT=1

Since my last post there has been major progress.
Seems that as long as I do the defines in the platformio.ini file this work, but when when using #define xxxxxxx within the main.cpp file it does not. Eh, workable.

now I have moved on to displaying jpegs with the TFT_Flash_Jpg example
it is working for the most part.

IMG_1114.mov

When using -D STM_PORTA_DATA_BUS=1 I get the line in the middle of some of the displayed files. Same few lines each time, but it doesn't appear in the others

If I don't include that, there is no line in the middle
