Question

Can we interface STM32F407 DISCO Board with TFT LCD via FSMC?

STM32F407VG Disco Board is without TFT LCD. I am learning to interface this board with a TFT LCD using FSMC. The FSMC WR pin (Write Enable) pin is used in the board as input in USB OTG interface. ( As far as I understand). Schematic part below.

Also I plan to use A18 as the Register select Pin which is also having an LED on board.

Regards

Thank you.

Since Nobody answered I will answer myself.

I have used FSMC to drive TFT even with the LEDS on board in the same pins. No issues, it is working.

Thanks
