I've written some code to make a FSMC connection between my STM32F407VET6 and a TFT LCD 240x320 pixels. I was checking this several times, however I can't recognize what's wrong. I'm using 16-bit data bus with FSMC_NE1, FSMC_A16, FSMC_NWE, FSMC_NOE. I've connected PE6 pin which is FSMC_A22 in FSMC interface. Now I'm wondering weather it can work with such configuration (I mean PE6 pin). All I get is white screen on my LCD as it is in RESET state.
Here's my code to configure FSMC:
void init_FSMC(void)

I'm using this address to write commands and data:
#define LCD_REG (*((volatile unsigned short *) 0x60000000))
#define LCD_RAM (*((volatile unsigned short *) 0x60020000))
LCD_RAM = data;
LCD_REG = command;
I have no idea what I am doing wrong. I know there is several similar topics, however none of them help with this issue. I'm trying to cope with that problem for several weeks - with no results.
I'm out of my mind... and don;t know to do next.
Thanks for any help
