As far as I searched, I couldnt find any instruction on using Touchgfx via fsmc. Even examples on Touchgfx designer was to use LTDC feature of microcontrollers. I wonder if developers of touchgfx has extend their platform to FSMC or if they have any intention to provide some code for using touchgfx on fsmc. I used stemwin successfully some days ago and I wonder if it is possible to use touchgfx on stm32f407vgtx (Discovery board.)
TouchGFX is interface agnostic (memory, display and otherwise), in a sense. There's no direct coupling between touchgfx and FMC/FSMC/LTDC/DSI/SPI/8080/.... It all depends on how you configure your hardware and what your intentions are.
EDIT:
With TouchGFX Generator (through CubeMX 5.5) you can configure TouchGFX to use a custom display interface and thus FMC/FSMC/SPI etc. Here's an article about it - Let me know if you have questions.
