Hi Manfred,
Much thanks, I will check out the chapters you refer to. Preliminary, we have 260K of internal SRAM, of which 150-230KB could be allocated for the GUI. We had previously used a display with external SDRAM, but the thinking at the moment is to use the internal SRAM of the STM32F429, having examined carefully the map file of the code of our existing product.
Kind Regards
