Using the DMA is the next step. DMA is useful when transferring the dump from SD to TFT. To use the text and primitive enough FSMC. Adafruit library contains a set of functions required. It is just necessary to port to stm32. In this library,I like the function change font size. In other libraries, it is not.
I looked proposed library. The library management software and TFT SPI. My version of the hardware control.
