Hi guys,
I am using the STM32F746ZGT6 with a 24Bit RGB-TFT and an external SDRAM memory.
In CubeMX I have seen, that I cant use the DQM lines together with the full 24-Bit wide bus for the TFT.
I want to use the SDRAM AS4C16M16SA. What disadvantage do I have if I do not connect the DQM lines? Or other question what is the best solution for using both parts together. It is okay not to use the whole memory, but I need a little bit external SDRAM memory.
Hope you can help me. Thanks!
