Im trying to drive 3.5 inch TFT LCD with STM32H743 using FMC. My setup is :
- ChipSelect: NE1
- Memory Type: LCD Interface
- LCD Register Select: A18
- Data: 8 Bits
My timing settings are (FMC Clock: 10Mhz):
- Address setup time in FMC clock: 3
- Data setup time in FMC clock: 2
- Bus Turn around time in FMC clock: 2
Here are the parts of code:
- #define FMC_BASE ((uint32_t)0x60000000)
- #define LCD_CMD (*((volatile uint32_t *)(FMC_BASE)))
- #define LCD_DATA (*((volatile uint32_t *)(FMC_BASE | (1 << 18))))
When I try to write a data, as shown in the attachment, my logic analyzer shows me multiple WR event occured and shows some weird signals on data line (D0-D3).
I do not understand where I did wrong...
