hey all,

i am using STM32F4 MCU. trying to connect LCD controller (ILI9342C) using FSMC.

i understand that i can use the 8 bit bus.

On the STM32 side or the LCD Controller side.

From the STM32 D8..15 would only be present if you used at 16-bit bus, and shifted the data into the high order byte

The key difference in 16-bit mode is that the sense of A0, and other address bits, is shifted
