Hi there, does anyone know whether stm32F303re has FSMS? If yes, how could I enable it so that I would be able to interface a TFT LCD LGDP display?

Datasheet says it has FSMC (I guess you meant that).

I don't know what kind of LCD you are talking about, but for 16-bit parallel interface, NOR flash interface is usually used, if the timing (especially hold time) allows.

If not, then NAND flash interface. I think, CubeMX doesn't support that kind of (mis)use, but you can configure a NOR/NAND flash interface in CubeMX, and in the code, reconfigure the pins not needed for the LCD interface for something else (like address pins and latch strobes). You also need one GPIO for selecting between register and data.

Perhaps look at design of STM32303E-EVAL board

https://www.st.com/en/evaluation-tools/stm32303e-eval.html

Reference manual states: (p168 / RM0316)

Only the STM32F303xD/E and STM32F398xE devices include the FSMC.

There's also inconsistent use of 'FSMC' and 'FMC' in the data sheet.

The table "Table 2. STM32F303xD/E family device features and peripheral counts" shows that STM32F303Rx doesn't have it, but STM32F303Vx and STM32F303Zx do.

The problem is that I'm trying to launch a tft lcd for the first time and I'm not sure datasheet will provide me enough hints as it is designed in a roundabout way(at least it seems like that to me). Did anybody make a similar project?

I wrote some code for a QVGA-display using 8080-interface (RGB565). I used FMC NAND of F427, because otherwise I couldn't get the data hold time long enough.
