I would like you use an external SRAM (is62wv2568bll) employing FMSC module in STM32F103xG. In example projects referred in AN2784 entitled "Using the high-density STM32F10xxx FSMC peripheral to drive external memories", there are some write/read examples. However, this examples aims to write/read blocks of data to/from external memory. What I want to do is to use this external memory like the internal RAM of the MCU. When I define a variable, this variable should be located to approriate place if the internal memory of the MCU is full. I think I need to configure both FSMC and IDE (IAR). Any help/suggestion is greatly appreciated.
