I want to connect a TFT with SSD1963 Controller to a Nucleo-144 F746ZGT. If i use GPIO lines to send data to the SSD1963, everything works fine. I choose the same GPIO Pins as if I would use the FMC so i do not need different Hardware, I only Change the initialisation of the used Pins. With GPIO Pin toggling, Speed is not satifying.
So i activate the FMC, but the Timings do not fit to the Needs of the SSD1963. The CS should rise before WR/RD and D/C like during GPIO mode. But as you can see CS rises at the same time as WR and D/C .
These are the Settings for FMC. How can I adjust the Timings to get a waveform with an early CS ? Can it be done just with Software or do i Need external Hardware ? Checked several documents (DM00166116 page 172, STM32F746 datasheet, AN2784, AN2790), but did not get a clue.
