    Fast Parallel Port (32bite wide) to interface external IC using STM32F7 or H7

    Mikolaj Z


      How fast it is possible to drive external IC using Paraller Port (32bit wide, mixed PINs from various port) via DMA or other technics. I have connected also exteral SDRAM to MCU.


      It is possible to achive about 40 - 50 MHz update freq ot entire port ?


      Thank you in advance for all sugesstions.
