I'll order Open-Smart 16 pin ILI9488 3.5inch 320x480.
It will arrive at me at the end of February.

Since prenticedavid/MCUFRIEND_kbv library says it only works with 28 pin shields, I did some looking for a library for the 16 pin board. I found this on YouTube from Frankie Chu.

He has a link to a google drive with an Arduino library for the ILI9488 16 pin board.

I wired up an Arduino Pro Mini 8Mhz 3.3V and got the graphicstest.ino to work with that library.
I just wish I knew how to port it for a STM32F411CE. Ha ha. That is way beyond me right now. Maybe it will help you though.
Thanks,

Perhaps OPEN-SMART products cannot follow high-speed GPIO-ON and GPIO-OFF.
I think it is necessary to operate with low speed GPIO-ON and GPIO-OFF.
prenticedavid/MCUFRIEND_kbv library use high-speed GPIO ON /OFF.
Perhaps Arduino library for the ILI9488 16 pin board use low speed GPIO ON /OFF.

I am just curious. What touchscreen library do you use with the Arduino-STM32-8bitTFT?
from arduino-stm32-8bittft.
I have never used a touch screen library.
Perhaps for this module you can read the touchscreen position with RD = Low & WR = High.
Position data is read from CX & CY.
But I haven't tried it.

Did you ever receive your order for Open-Smart 16 pin ILI9488 3.5inch 320x480 display?
from arduino-stm32-8bittft.
I got these Open-Smart 16-pin display.
OPEN-SMART S6D1121 16Pin-Parallel
OPEN-SMART ST7775 16Pin-Parallel
OPEN-SMART ST7783 16Pin-Parallel
OPEN-SMART R61509V 16Pin-Parallel
OPEN-SMART ILI9488 16Pin-Parallel
I found that these display cannot follow high-speed GPIO-ON and GPIO-OFF.
It's hardware side issues.
The Arduino Pro Mini 8Mhz 3.3V is slow so they work.
These Open-Smart Shields work fine with high speed.
OPEN-SMART ILI9225 TFT-Shield
OPEN-SMART ILI9327 TFT-Shield
OPEN-SMART ILI9340 TFT-Shield
